Terrazza Triennale's chef Matteo Ferrario is a friend, someone who orders truffle all year long—from white to uncinate, from black summer truffle to burgundy truffle, he can order up to 40 kilos per year—and loves everything about Fede and Filippo, from their fall/winter collection to the spring/summer one, not to mention all the other ancillary products they come equipped with, such as mushroom and truffle spread, truffle salt, mustard, and truffle-flavored extra-virgin olive oil.
The uncinate fasciculus appears to have a role in some, but not all, types of learning and memory. Reversal learning, in which a stimulus-reward association is learned over many trials, then reversed such that the initial stimulus is no longer is associated with a reward, is associated with individual variation in the uncinate fasciculus . In addition, the ability to learn associations through trial and error, such as the pairing of a name with a face, correlates with uncinate fasciculus microstructure. This relates to early work showing that surgical damage to the uncinate fasciculus is reliably associated with deficits in proper name retrieval.
587 Pp. Smithsonian Institution Press, , Birds and reptiles have bony uncinate processes on their ribs that project caudally from the vertical section of each rib. These serve to attach sacral muscles and also aid in allowing greater inspiration. Crocodiles have cartilaginous uncinate processes.
Fucheng, Zhang, Zhou Zhoghe, Hou Lianhai & Gu Gang 2001. Early diversification of birds: Evidence from a new opposite bird. Chinese Science Bulletin. 46(11):945-949 PDF Although among living vertebrates, bony uncinate processes are unique to birds, cartilaginous uncinate processes are present in crocodiles.
Abnormalities within the fiber bundles of the uncinate fasciculus have been linked to a host of neuropsychiatric disorders, some consistently, some inconsistently. For instance, studies of individuals with social anxiety and schizophrenia have reported changed in diffusion metrics of the uncinate. Unfortunately these findings frequently fail to replicate, the directionality of effects is mixed, and there is no specificity between findings in the uncinate and these particular diseases. An in-depth review of the clinical literature noted that “the uncinate fasciculus per se plays either a small role, or no role, in anxiety disorders “ and that “the results of DTI studies measuring changes in uncinate fractional anisotropy values in schizophrenics are contradictory.” Future researchers should focus on using superior diffusion imaging methods as well correlating specific symptoms, rather than presence or absence of disease state, with changes in white matter.
The pancreatic notch is a separation between the neck of pancreas and the uncinate process of pancreas.
The anterior tubercle on the sixth cervical vertebra is called the carotid tubercle because it separates the carotid artery from the vertebral artery. There is a hook-shaped uncinate process on the side edges of the top surface of the bodies of the third to the seventh cervical vertebrae and of the first thoracic vertebra. Together with the vertebral disc, this uncinate process prevents a vertebra from sliding backwards off the vertebra below it and limits lateral flexion (side-bending). Luschka's joints involve the vertebral uncinate processes.
The true ribs are small projections, with small, hooked bones, called uncinate processes, found on the rear of each rib. This feature is also present in birds. The tuatara is the only living tetrapod with well-developed gastralia and uncinate processes. In the early tetrapods, the gastralia and ribs with uncinate processes, together with bony elements such as bony plates in the skin (osteoderms) and clavicles (collar bone), would have formed a sort of exoskeleton around the body, protecting the belly and helping to hold in the guts and inner organs.
A stylised dove skeleton. Key: 1\. skull 2\. cervical vertebrae 3\. furcula 4\. coracoid 5\. uncinate processes of ribs 6\. keel 7\.
Birds have spurs called "uncinate processes" on the rear edges of their ribs, and these give the chest muscles more leverage when pumping the chest to improve oxygen supply. The size of the uncinate processes is related to the bird's lifestyle and oxygen requirements: they are shortest in walking birds and longest in diving birds, which need to replenish their oxygen reserves quickly when they surface. Non- avian maniraptoran dinosaurs also had these uncinate processes, and they were proportionately as long as in modern diving birds, which indicates that maniraptorans needed a high-capacity oxygen supply. News summary at Plates that may have functioned the same way as uncinate processes have been observed in fossils of the ornithischian dinosaur Thescelosaurus, and have been interpreted as evidence of high oxygen consumption and therefore high metabolic rate.
In contrast, microstructural changes to the uncinate fasciculus have been consistently been linked to conduct disorder and psychopathy. This is consistent with studies of gray matter volume which reported that neural regions linked by the uncinate fasciculus—the orbitofrontal cortex and temporal polar cortex/Brodmann area 38 (also known as the temporal pole/temporal polar cortex/anterior temporal lobe)— have decreased volume in individuals with antisocial personality disorder /psychopathy relative to control . Interestingly, Phineas Gage, a railroad worker who had an iron bar go through his left frontal lobe also sustained damage to the uncinate fasciculus.
This stylised bird skeleton highlights the uncinate processes The uncinate processes of the ribs are extensions of bone that project caudally from the vertical segment of each rib. (Uncinate means hooked from Latin uncinatus, from uncinus, barb, from uncus, hook.) They are found in birds (except for screamers), reptiles, and the early amphibian Ichthyostega. These processes can serve to attach scapula muscles, and help to strengthen the rib cage overlapping with the rib behind them. They are also shown to have a role in respiration by increasing the effectiveness of muscles involved in inspiration including the appendicocostal muscles.
The uncinate process has also been reported in fossil vertebrates including Sphenodon, Caudipteryx, oviraptorids, Confuciusornis, Chaoyangia, and Longipteryx; however it does not occur in Archaeopteryx.
In 12-year-old males that were preterm, abnormalities measured by fractional anisotropy in the left anterior uncinate correlated with verbal IQ, full-scale IQ, and Peabody Picture Vocabulary Test-Revised scores. In 10-year-old children who have suffered socioemotional deprivation, the left uncinate fasciculus shows reduced fractional anisotropy compared to that in other children, and this might underlie their cognitive, socioemotional, and behavioral difficulties.
Sometimes the pancreas fails to develop normally and there may be congenital defects associated with the uncinate process. The uncinate process may split and encircle the duodenum, which is known as an annular pancreas.Drake et al, Gray's Anatomy for Students, Churchill Livingstone/Elsevier (2010), 2nd edition, chapter 4 There is also a common condition called pancreas divisum where the dorsal and ventral pancreas do not fuse properly.
The uncinate fasciculus has the longest period of development in terms of fractional anisotropy as it alone amongst the major white fibre tracks continues to develop until the age of 30. Developmental disorders with core problems relating to memory retrieval, reward and valuation computation, and impulsive decision making may be linked to aberrations in uncinate fasciculus microstructure, e.g. temporal lobe epilepsy and conduct disorder. Moreover it seems to be developmentally vulnerable.
The seed is ovoid to circular, compressed, with leathery, smooth or papillose seed coat. The seed contains the half-annular, uncinate or curved embryo and copious perisperm (feeding tissue).
In the ethmoid bone, a sickle shaped projection, the uncinate process, projects posteroinferiorly from the ethmoid labyrinth. Between the posterior edge of this process and the anterior surface of the ethmoid bulla, there is a two-dimensional space, resembling a crescent shape. This space continues laterally as a three-dimensional slit-like space - the ethmoidal infundibulum. This is bounded by the uncinate process, medially, the orbital lamina of ethmoid bone (lamina papyracea), laterally, and the ethmoidal bulla, posterosuperiorly.
Birds have uncinate processes on the ribs. These are hooked extensions of bone which help to strengthen the rib cage by overlapping with the rib behind them. This feature is also found in the tuatara (Sphenodon).
The peridial hyphae of A. californiense also have a pale orange-brown color. These septate peridial hyphae are asperulate and cuticularized. A loose network appears with all the peridial hyphae together. A. californiense have uncinate appendages.
The overlapping uncinate processes, which stiffen the ribcage, were very well developed. The wing bones (humerus, radius, ulna, carpometacarpus) were short but robust compared to other pigeons. The leg bones were similar to those of other pigeons.
The uncinate process can be attached to either the lateral nasal wall, on the lamina papyracea (50%), the anterior cranial fossa, on the ethmoidal roof (25%), or the middle concha (25%). The superior attachment of the uncinate process determines the drainage pattern of the frontal sinus. In the first case, the infundibulum and the frontal recess are separated from each other, forcing the frontal sinus to drain directly into the middle meatus and not into the ethmoidal infundibulum. With the other configurations, the sinus will drain, firstly, into the infundibulum.
After the accident, his personality was radically transformed, becoming impulsive, making poor decisions, and failing to follow social norms and conventions. Last, consistent abnormalities in the uncinate fasciculus are found in Alzheimer's disease, semantic dementia, and temporal lobe epilepsy.
It is differentiated from closely related species by its strongly curved column without column wings and its broadly rhombic- elliptic lip with 2 uncinate calli at the base. It also has two pollinia attached by long and prominent caudicles (not stipes), to a distinct sticky disc.
The uncinate fasciculus is a hook-shaped bundle of axons that links anterior portions of the temporal lobe with the inferior frontal gyrus and the lower surfaces of the frontal lobe. It arises in the anteriorior temporal lobe and amygdala,in the temporal lobe curving in an upward pathway behind the external capsule inward of the insular cortex and continuing up into the posterior part of the orbital gyrus.. It does not appear to have cell bodies in the hippocampus proper. The average length of the uncinate fasciculus is 45 mm with a range 40–49 mm. Its volume in adults is 1425.9±138.6 mm3, being slightly larger in men, at 1504.3±150.4, than women 1378.5±107.4.
Because of the fragility of the plates, and the fact that they may not have always turned to bone in the living animal, they may have been more widespread than currently known. Novas and colleagues suggested that the plates may be homologous to uncinate processes, strip-like bony projections found on the ribs of a variety of animals including the tuatara, crocodiles, birds, and some maniraptoran theropod dinosaurs. In birds, uncinate processes help to ventilate the lungs, working with rib cage muscles, and Novas and colleagues proposed a similar function for the plates of Talenkauen. This homology was rejected in a more recent study by Richard Butler and Peter Galton because of the plates' form.
Tickle, Peter G., A. Roland Ennos, Laura E. Lennox, Steven F. Perry and Jonathan R. Codd 2007. Functional significance of the uncinate processes in birds. Journal of Experimental Biology 210:3955-3961 Abstract The screamers (Anhimidae) are unique in lacking this process. The process has also been noted in some enantiornitheans.
Like D. speciosum and D. pulchrum, it has smooth leaf- surfaces. The flowers can be bright yellow, orange, pink or red. D. lavisii can be distinguished by its recurved, hooked (uncinate) leaf-tips. This character, especially prominent in new leaves, and is also seen in D. edwardsiae and D. uniondalense.
While previously thought to connect Wernicke's area and Broca's area, new research demonstrates that the arcuate fasciculus instead connects to posterior receptive areas with premotor/motor areas, and not to Broca's area. Consistent with the word recognition site identified in brain imaging, the uncinate fasciculus connects anterior superior temporal regions with Broca's area.
University of Arizona Press, Tucson P. maculatus is a trailing perennial herb with a large, woody taproot. Leaves are trifoliate, oval, up to 8 cm (3.2 in) long, with small uncinate (hooked) hairs. Leaf blades tend to be oriented vertically so they do are not pressed against the ground. Flowers are purple.
Below the bulla ethmoidalis, and partly hidden by the inferior end of the uncinate process of ethmoid bone, is the maxillary hiatus (or ostium maxillare, or maxillary sinus ostium, or maxillary ostium, or opening from the maxillary sinus); in a frontal section this opening is seen to be placed near the roof of the sinus. In the articulated skull this aperture is much reduced in size by the following bones: the uncinate process of the ethmoid above, the ethmoidal process of the inferior nasal concha below, the vertical part of the palatine behind, and a small part of the lacrimal above and in front; the sinus communicates with the middle meatus of the nose, generally by two small apertures left between the above-mentioned bones.
The diameter of the ascocarp is 150-555μm. The spore mass fills the ascocarps between one-third and three-fourths of the total volume at peak maturity. The surrounding Gymnothecium has septate appendages that are straight and elongated. Branching points present as uncinate, or curved spines that are wider or flattened at the apices.
Behind the lacrimal process of the inferior nasal conchae lies a broad, thin plate, the ethmoidal process, which ascends to join the uncinate process of the ethmoid; from its lower border a thin lamina, the maxillary process, curves downward and lateralward; it articulates with the maxilla and forms a part of the medial wall of the maxillary sinus.
The paranasal sinuses are connected to the nasal cavity through small orifices called ostia. Most of these ostia communicate with the nose through the lateral nasal wall, via a semi-lunar depression in it known as the semilunar hiatus. The hiatus is bound laterally by a projection known as the uncinate process. This region is called the ostiomeatal complex.
Life reconstruction of Zhongjianosaurus yangi based on the holotype skeleton Zhongjianosaurus is distinguishable from other microraptorines in the following autapomorphies. Proportionally long ossified uncinate processes are fused to the dorsal ribs. A widely arched furcula is present with slender and posteriorly curved clavicular rami. The humeral proximal end is strongly offset medially from the humeral shaft.
The long metatarsals present in Daliansaurus suggest that its running capabilities were better-developed than those of other troodontids. At the same time, the possible presence of uncinate processes on its ribs would have provided reinforcement for the rib cage, as well as an increase in the effectiveness of the muscles involved in breathing, as in modern birds.
The uncinate fasciculus is a bi-directional pathway between the temporal lobe and frontal lobe; it is traditionally considered to be part of the limbic system.. It has been proposed that the uncinate fasciclus allows mnemonic representations stored in the temporal lobe to interact with and guide decision making in the frontal lobe. Diffusion tensor imaging, a reconstruction model available from a diffusion MRI scan, shows a greater fractional anisotropy on the left side than on the right. The difference in this measure of anisotropy has been linked to the left hemispheric specialization for language. However, the use of electrical brain stimulation upon it fails to disrupt language, suggesting it might not be involved in language, though it is possible that this disruption failed to happen because it was functionally compensated by alternative pathways.
Codd, J. R., D. F. Boggs, S. F. Perry, and D. R. Carrier. 2005. Activity of three muscles associated with the uncinate processes of the giant Canada Goose Branta canadensis maximus. Journal of Experimental Biology 208:849-857. Full text The processes are short in walking birds and long in diving species and are of intermediate length in non-specialist birds.
Pancreatic development begins with the formation of a dorsal and ventral pancreatic bud. Each joins with the foregut through a duct. The dorsal pancreatic bud forms the neck, body, and tail of the developed pancreas, and the ventral pancreatic bud forms the head and uncinate process. The definitive pancreas results from rotation of the ventral bud and the fusion of the two buds.
Vertebrae without pneumatopores would have indicated the boundaries between three air-sac systems: those of the neck base, the lungs, and the abdomen. The double rib heads would indicate a rather stiff thorax, ventilated by the gastralia. A system of hook-like uncinate processes on the ribs as with the Maniraptoriformes, allowing the ribcage to move flexibly, in articulation with an ossified sternum, was absent in Scipionyx.
Bracteria polyphylla (Poir.) DC, Clitoria pinnata (Pers.) R.H. Smith & G.P. Lewis, Clitoria polyphyllaPoir., Galactia pinnata Pers. Erect shrub 1–2.5 m tall, apically a scandent liana. Leaves imparipinnate, leaflets commonly 13–21, oblong to elliptic, 2.5–6 cm long x 1–2.5 cm wide, dark green with micro-uncinate pubescent above, pale with rufo appressed-pilose pubescence below. Inflorescences pseudoracemose, 4–24 cm long; peduncle rufo-pilose.
In culture, colonies of U. uncinatus are yellow to orange-brown to red-brown in colour, growing paler towards the margin. Like other members of Uncinocarpus, it develops hooked and occasionally spiralling (uncinate) appendages which typically, but not always, possess spore-bearing structures (gymnothecia). The appendages of U. uncinatus are thick and wide to the distal end, unlike that of U. reesii, which taper to a point.
Uncinocarpus reesii is a species of saprotrophic microfungi that grows in soil and on keratinous materials such as hair, feathers and skin. It was the first species to be designated as part of the genus Uncinocarpus, owing in part to its characteristic development of hooked (uncinate) appendages. As the closest non-pathogenic relative of Coccidioides immitis and C. posadasii, it has become a subject of research interest.
The semilunar hiatus or hiatus semilunaris, is a crescent-shaped groove in the lateral wall of the nasal cavity just inferior to the ethmoid bulla. It is the location of the openings for maxillary sinus. It is bounded inferiorly and anteriorly by the sharp concave margin of the uncinate process of the ethmoid bone, superiorly by the ethmoid bulla, and posteriorly by the middle nasal concha.
Caudipteryx had uncinate processes on the ribs, birdlike teeth, a first toe which may or may not be partially reversed and overall body proportions that are comparable to those of modern flightless birds. PDF Supplementary information In 2016 Caudipteryx zoui was estimated at 78 cm (2.5 ft) and 2.2 kg (4.8 lbs) while Caudipteryx dongi slightly larger at 80 cm (2.6 ft) and 2.3 kg (5 lbs).
Vertebral foramina are roughly circular in shape. The top surface of the first thoracic vertebra has a hook-shaped uncinate process, just like the cervical vertebrae. The thoracolumbar division refers to the thoracic and lumbar vertebrae together, and sometimes also their surrounding areas. The thoracic vertebrae attach to ribs and so have articular facets specific to them; these are the superior, transverse and inferior costal facets.
Its ribcage was not strengthened by ossified uncinate processes but cartilaginous processes were likely present. The Las Hoyas Unit 3 site was once a forest surrounding a lake; the climate was warm with a distinct dry season. Since the skull is not known, the diet of Iberomesornis remains a subject of guesswork. It perhaps hunted insects and other small animals, plucking them out of the air or from the ground.
"Local Brain Functional Activity Following Early Deprivation: A Study of Postinstitutionalized Romanian Orphans". NeuroImage. 14. pp. 1,290–1,301. Further damage occurs in the white matter of the uncinate fasciculus. This structure is responsible for providing a major pathway of communication between areas for higher cognitive and emotional functioning, such as the amygdala and frontal lobe.Eluvathingal, T.J.; Chugani, H.T.; Behen, M.E.; Juha´sz, C.; Muzik, O.; Maqbool, M.; et al. (2006).
In birds, ribs are present as distinct bones only on the thoracic region, although small fused ribs are present on the cervical vertebrae. The thoracic ribs of birds possess a wide projection to the rear; this uncinate process is an attachment for the shoulder muscles. Usually dogs have 26 ribs. Mammals usually also only have distinct ribs on the thoracic vertebra, although fixed cervical ribs are also present in monotremes.
They have reduced brain activity in the orbital prefrontal cortex, amygdala, hippocampus, temporal cortex, and brain stem. They also showed less developed white matter connections between different areas in their cerebral cortices, particularly the uncinate fasciculus. Conversely, enriching the experience of preterm infants with massage quickens the maturating of their electroencephalographic activity and their visual acuity. Moreover, as with enrichment in experimental animals, this associates with an increase in IGF-1.
A small uncinate process emerges from below the head, situated behind the superior mesenteric vein and sometimes artery. The neck of the pancreas separates the head of the pancreas, located in the curvature of the duodenum, from the body. The neck is about wide, and sits in front of where the portal vein is formed. The neck lies mostly behind the pylorus of the stomach, and is covered with peritoneum.
On the other hand, its shoulder girdle was apparently ill-adapted to flapping flight and its furcula was unusual, with a hypocleidum similar to more advanced avialans but a general anatomy even more primitive than in Archaeopteryx. The humerus was large and bore holes, apparently to save weight, as in the Confuciusornithidae. The skull has a handful of teeth in the upper jawtip only. Sapeornis had gastralia but no (or unossified) uncinate processes.
The ventral and dorsal pancreatic buds (or pancreatic diverticula) are outgrowths of the duodenum during human embryogenesis. They join together to form the adult pancreas. The proximal portion of the dorsal pancreatic bud gives rise to the accessory pancreatic duct, while the distal portion of the dorsal pancreatic bud and ventral pancreatic bud give rise to the major pancreatic duct. The ventral pancreatic bud develops into the pancreatic head and uncinate process.
The uncinate fasciculus is a white matter association tract in the human brain that connects parts of the limbic system such as the temporal pole, anterior parahippocampus, and amygdala in the temporal lobe with inferior portions of the frontal lobe such as the orbitofrontal cortex. Its function is unknown though it is affected in several psychiatric conditions. It is one of the last white matter tracts to mature in the human brain.
This makes the two parts of the pancreas rotate around the duodenum. They then fuse; the dorsal pancreatic bud becomes the body, tail, and isthmus of the pancreas. The isthmus (also called the central pancreas) is the region of the gland that runs anterior to the superior mesenteric artery; by convention, it divides the right and left sides of the pancreas. The ventral pancreatic bud forms the pancreatic head and uncinate process.
Fischer later recognized the existence of ascospores in M. chartarum, but a distinct lack of conidial structures. In 1893, Schroeter reviewed family Gymnoascaceae and placed species with uncinate appendages within the genus, Myxotrichum without regard for other characteristics. Different forms of M. chartarum were isolated by Robak and Udagawa that resembled a phenotypically similar species. The isolate discovered by Robak (1932) of M. carminoparum resembled M. chartarum in every way except in the characteristically flattened apical area.
In anatomy, Luschka's joints (also called uncovertebral joints, neurocentral joints) are formed between uncinate process or "uncus" below and uncovertebral articulation above. They are located in the cervical region of the vertebral column between C3 and C7. Two lips project upward from the superior surface of the vertebral body below, and one projects downward from the inferior surface of vertebral body above. They allow for flexion and extension and limit lateral flexion in the cervical spine.
The glands continue to develop but the duct systems anastomose. The main pancreatic duct is formed by the fusion of the dorsal and ventral pancreas. The embryology also explains the strange zig-zag course of the main pancreatic duct and the occasional appearance of an accessory pancreatic duct. The uncinate process, unlike the remainder of the organ, passes posteriorly to the superior mesenteric vein (it can pass posteriorly to the superior mesenteric artery, but this is less common).
Symptoms include difficulty breathing through the nose, swelling and pain around the nose and eyes, postnasal drainage down the throat, and difficulty sleeping. CRS is a common condition in pediatric patients and young adults. The purpose of FESS in treatment of CRS is to remove any anatomical obstructions that prevent proper mucosal drainage. A standard FESS includes removal of the uncinate process, and opening of the anterior ethmoid air cells and Haller cells as well as the maxillary ostium, if necessary.
C. beishanensis, known only from a single partial skeleton, is relatively poorly known compared to other primitive euornitheans. Chaoyangia were small, basal euornithean birds characterized by more than eight fused sacral vertebrae (those connected to the hips), uniquely long, slender, and angled uncinate processes on the ribs, and a distinct 'neck' in the upper leg bone (femur). Overall, the known skeleton is very similar to another primitive Chinese euornithean bird, Zhongjianornis, which is known from a much more complete skeleton.
Cacops morrisi is named in honor of Tony Morris, who discovered one of its two specimens. Many specimens have been found in the Dolese Brothers Limestone Quarry, near Richards Spur, Oklahoma. Cacops morrisi has a skull that differs from C. aspidephorus in having a snout that is slightly longer than its post-orbital region, a shorter distance between the orbit and the temporal emargination, and uncinate processes of the ribs. Cacops woehri is named in honor of Daniel Woehr, who is an amateur collector of fossils.
The screamers are three South American bird species placed in family, Anhimidae. They were thought to be related to the Galliformes because of similar bills, but are more related to ducks (family Anatidae),Todd, F. (1991) and most closely related to the magpie goose. The clade is exceptional within the living birds in lacking uncinate processes of ribs. The three species are, the horned screamer (Anhima cornuta), the southern screamer or crested screamer (Chauna torquata) and the northern screamer or black-necked screamer (Chauna chavaria).
In culture, colonies of U. reesii grow moderately fast and are yellowish-white to buff in colour, are flat and dense in shape, and range from velvety to powdery in texture. Arthroconidia of U. reesii tend to be broad compared to most Malbranchea, ranging from approximately 2.5-3.5 μm x 3.5-6 μm in size. As a heterothallic species, two compatible "sexes" are required for sexual reproduction to occur. As with other members of the genus Uncinocarpus, U. reesii can develop hooked (uncinate) appendages on vegetative hyphae.
Note that variation in distribution is observed within individuals, so abnormalities of this characteristic likely play a significant role in all psychological illnesses. Individual alterations are produced by differences within glutamatergic pathways within the limbic system, which are also implicated in other psychotic syndromes. Among the alterations of both synaptic and global structure, the most significant abnormalities are observed in the uncinate fasciculus and the cingulate cortex. The combination of these creates a profound dissymmetry of prefrontal inhibitory signaling, shifted positively towards the dominant side.
The specimen's remains preserve the four most posterior cervical vertebrae (likely 7-10 in regards to placement). Seven dorsal vertebrae are known, while eight dorsal ribs are known from the left side of the specimen in comparison to the five preserved for the right side. Five left uncinate processes are preserved as well. The caudal series of vertebrae are represented by 26 articulated caudal vertebrae, probably missing only the first caudal vertebra, likely making a full count of 27 caudal vertebrae in the tail.
The tree can grow to a maximum height of that has obscure stipules on the branchlets. Like most species of Acacia it has phyllodes rather than true leaves. The evergreen phyllodes have a linear shape and are straight or slightly sickle shaped with a length of and a width of . The dark green coloured phylloeds are thin and pliable and have an apex that is occasionally uncinate and have six to nine anastomosing veins of which one to three are much more clearly defined than the others.
Selective hypometabolism of glucose has been observed in the anterior temporal lobe, as well as the medial temporal lobe and limbic areas. Damage to white matter tracts connecting the anterior temporal cortex to the inferior longitudinal, arcuate, and uncinate fasciculi, which are regions of the language network, is also seen using diffusion tensor imaging. Imaging also shows the integrity of the axonal connections from the anterior temporal cortex to frontal and posterior associative areas to be altered. Functional abnormalities have also been observed in hippocampal structures, the ventromedial prefrontal cortex, and the cingulate cortex.
Neotenic branchiosaurids experienced isometric growth of cranial bones while retaining juvenile features noted above. Adult branchiosaurid neotenes are distinguished from larval neotenes by accentuated laval-type skull roof ornamentation, increased ossification (although not as extensively as in metamorphosed specimens), and development of uncinate process on the anterior trunk ribs. Such phenotypic plasticity in the form of facultative neoteny has been reported in modern lissamphibians and has been suggested to also be highly advantageous in the high altitude habitats of branchiosaurids where the harsh, continually changing conditions would have made aquatic life favorable.Schoch, R.R. 2004.
The dorsal ribs lack uncinate process, and the sternum is also unossified, like other troodontids. Like other theropods, the first pair of the gastralia near the front of the torso is noticeably more robust, particularly in the central portion. Similar to other paravians, the caudal vertebrae of Jianianhualong become increasingly longer towards the back of the tail; for instance, the fifteenth caudal is about twice as long as the sixth. From the twenty-third caudal backwards, the sides of the caudals become compressed such that they are sub-triangular.
Cytoarchitecturally it is bounded caudally by the inferior temporal area 20, the middle temporal area 21, the superior temporal area 22 and the ectorhinal area 36 (Brodmann-1909). Cytoarchitectonic and chemoarchitectonic studies find that it contains at least seven subareas, one of which, "TG", is unique to humans. The temporal pole is a paralimbic region involved in high level semantic representation and socio-emotional processing. The uncinate fasciculus provides a direct bidirectional path to the orbitofrontal cortex, allowing mnemonic representations stored in the temporal pole to bias decision making in the frontal lobe.
Following the curve anteriorly leads into the infundibulum of the frontonasal duct, which drains the frontal sinus. The anterior ethmoidal cells of the ethmoidal sinus open into the front part of the infundibulum as well. In slightly over 50% of subjects, this is directly continuous with the frontonasal duct from the frontal air sinus. When the anterior end of the uncinate process fuses with the front part of the bulla, however, this continuity is interrupted and the frontonasal duct then drains directly into the anterior end of the middle meatus.
Daliansaurus (meaning "Dalian reptile") is a genus of small troodontid theropod dinosaur, measuring approximately long, from the Early Cretaceous of China. It contains a single species, D. liaoningensis, named in 2017 by Shen and colleagues from a nearly complete skeleton preserved in three dimensions. Daliansaurus is unusual in possessing an enlarged claw on the fourth digit of the foot, in addition to the "sickle claw" found on the second digit of the feet of most paravians. It also has long metatarsal bones, and apparently possesses bird-like uncinate processes (a first among troodontids).
Daliansaurus has at least nine cervical vertebrae, probably thirteen dorsal vertebrae, five sacral vertebrae, and at least twenty-eight caudal vertebrae in the tail. Out of the sacral vertebrae, the fifth has the widest transverse processes in Daliansaurus, while the third is the widest in Sinovenator. The front margin of the process is also less strongly concave in Daliansaurus. The ribs of two of the dorsal vertebrae unusually appear to bear uncinate processes, in the form of curved and rod- like projections similar to those of Velociraptor, Linheraptor, and Heyuannia.
Land in section 10 of the Hundred of Kingsford was added on 7 December 1972 and in Section 135 of the Hundred of Parilla was added on 17 June 1976. As of 2016, it covered an area of . In 1980, it was described as follows: > This park contains a discrete area of steep, irregular sand dunes supporting > very mature mallee vegetation. The park provides habitat for numerous mallee > species including the threatened mallee fowl… Dominant vegetation is tall, > dense Eucalyptus incrassata mallee with Melaleuca lanceolata, M. uncinate > and Callitris verrucosa.
Life restoration Excluding the tail, Longipteryx was some 15 cm long overall in life. It had a long bill — longer than the rest of the head — with a few hooked teeth at the tip, and, as the name implies, proportionally long and strong wings. Although it was primitive insofar as that it had two long separate fingers with claws and a stubby thumb, the flight apparatus was generally quite well developed, and unlike most other birds of its time it possessed uncinate processes which strengthened the ribcage. Its claws and toes were long and strong while the leg was quite short.
Functional endoscopic sinus surgery (FESS) is a minimally invasive surgical treatment which uses nasal endoscopes to enlarge the nasal drainage pathways of the paranasal sinuses to improve sinus ventilation. This procedure is generally used to treat inflammatory and infectious sinus diseases, including chronic rhinosinusitis that doesn't respond to drugs, nasal polyps, some cancers, and decompression of eye sockets/optic nerve in Graves ophthalmopathy. In the surgery, an otolaryngologist removes the uncinate process of the ethmoid bone, while visualizing the nasal passage using a fiberoptic endoscope. FESS can be performed under local anesthesia as an outpatient procedure.
The salience network is primarily anchored at the AI and dACC. The node in the AI corresponds with the dorsal-anterior division distinguished in meta analyses of task-positive network related neuroimaging studies. The AI and dACC are linked via a white matter tract along the uncinate fasciculus. The subcortical nodes have yet to be structurally linked to the AI and dACC, however both seed-based and resting-state studies have observed intrinsic connectivity of the cortical nodes, with subcortical nodes consisting of the sublenticular extended amygdala, the putamen, the dorsomedial thalamus, the ventral striatum, and the substantia nigra/ventral tegmental area.
It has also been suggested that because pedophilic offenders have also been found to have a reduced BSTc, a feminine BSTc may be a marker for paraphilias rather than transsexuality. In a review of the evidence in 2006, Gooren confirmed the earlier research as supporting the concept of transsexuality as a sexual differentiation disorder of the sex dimorphic brain. Dick Swaab (2004) concurs. In 2008, a new region with properties similar to that of BSTc in regards to transsexuality was found by Garcia-Falgueras and Swaab: the interstitial nucleus of the anterior hypothalamus (INAH3), part of the hypothalamic uncinate nucleus.
Despite this, the implication of a wishbone-bearing dinosaur was blatantly ignored until much later, and for many years the state of dinosaur research stagnated, possibly due to the effects of the Depression and World War II.Paul (2010) p. 10. The reinvigoration of interest in the dinosaur–bird link was largely due to the discoveries and research of paleontologist John Ostrom in the 1960s. In particular was his discovery and description of the well-preserved dromaeosaur dinosaur Deinonychus. Ostrom described Deinonychus as being extremely bird- like, with avian features such as a furcula, large sternal plates, horizontal posture, a birdlike spine, and ossified sternal ribs and uncinate processes.
Structures such as the corona radiata, occipital-frontal fasciculus and uncinate fasciculus project to the claustrum from frontal, pericentral, parietal and occipital regions. Reciprocal connections also exist with motor, somatosensory, auditory and visual cortical regions. Altogether, these findings leave the claustrum as the most highly connected structure per regional volume in the brain and suggest that it may serve as a hub to coordinate activity of cerebral circuits. Interestingly, even with this extensive connectivity, most projections to and from the claustrum are ipsilateral (although there are still contralateral projections), and little evidence exists to describe its afferent or efferent connections with the brainstem and spinal cord.
Above and at the back of the superior concha is the sphenoethmoidal recess which the sphenoidal sinus opens into. The superior meatus occupies the middle third of the nasal cavity’s lateral wall. The middle meatus is the middle-sized and located nasal opening, lying underneath the middle concha and above the inferior concha where the meatus extends along its length. On it is a curved fissure, the hiatus semilunaris, limited below by the edge of the uncinate process of the ethmoid and above by an elevation named the bulla ethmoidalis; the middle ethmoidal cells are contained within this bulla and open on or near to it.
In front of the lamina papyracea are some broken air cells which are overlapped and completed by the lacrimal bone and the frontal process of the maxilla. A curved lamina, the uncinate process, projects downward and backward from this part of the labyrinth; it forms a small part of the medial wall of the maxillary sinus, and articulates with the ethmoidal process of the inferior nasal concha. The medial surface of the labyrinth forms part of the lateral wall of the corresponding nasal cavity. It consists of a thin lamella, which descends from the under surface of the cribriform plate, and ends below in a free, convoluted margin, the middle nasal concha.
Through the hiatus semilunaris the meatus communicates with a curved passage termed the infundibulum, which communicates in front with the anterior ethmoidal cells and in rather more than fifty percent of skulls is continued upward as the frontonasal duct into the frontal air-sinus; when this continuity fails, the frontonasal duct opens directly into the anterior part of the meatus. Below the bulla ethmoidalis and hidden by the uncinate process of the ethmoid is the opening of the maxillary sinus (ostium maxillare); an accessory opening is frequently present above the posterior part of the inferior nasal concha. The inferior meatus is the largest of the three. It lies below the inferior concha and above the nasal cavity. It extends most of the length of the nasal cavity’s lateral wall.
In Collected Essays IV: pp 46-138 original text w/ figures The mounted skeleton of a Velociraptor, showing the very bird-like quality of the smaller theropod dinosaurs Discoveries in northeast China (Liaoning Province) demonstrate that many small theropod dinosaurs did indeed have feathers, among them the compsognathid Sinosauropteryx and the microraptorian dromaeosaurid Sinornithosaurus. This has contributed to this ambiguity of where to draw the line between birds and reptiles.Norell, M & Ellison M (2005) Unearthing the Dragon, The Great Feathered Dinosaur Discovery Pi Press, New York, Cryptovolans, a dromaeosaurid found in 2002 (which may be a junior synonym of Microraptor) was capable of powered flight, possessed a sternal keel and had ribs with uncinate processes. Cryptovolans seems to make a better "bird" than Archaeopteryx which lacks some of these modern bird features.
People scoring 25 or higher in the PCL-R, with an associated history of violent behavior, appear to have significantly reduced mean microstructural integrity in their uncinate fasciculus—white matter connecting the amygdala and orbitofrontal cortex. There is evidence from DT-MRI, of breakdowns in the white matter connections between these two important areas. Although some studies have suggested inverse relationships between psychopathy and intelligence, including with regards to verbal IQ, Hare and Neumann state that a large literature demonstrates at most only a weak association between psychopathy and IQ, noting that the early pioneer Cleckley included good intelligence in his checklist due to selection bias (since many of his patients were "well educated and from middle-class or upper-class backgrounds") and that "there is no obvious theoretical reason why the disorder described by Cleckley or other clinicians should be related to intelligence; some psychopaths are bright, others less so". Studies also indicate that different aspects of the definition of psychopathy (e.g.
Their second pharyngobranchial is greatly elongated posterolaterally away from third pharyngobranchial, which lacks a cartilaginous condyle to articulate with the preceding, but is contacted by the elongated uncinate process of the second epibranchial. Other features include the position of the pelvic fins far back on the body, the fused medial processes of pelvic girdle, and the presence of an adipose fin (which is also typical for the Protacanthopterygii). The larvae of some Aulopiformes are extremely bizarre-looking, with elongated fins, and do not resemble the adult animals. They were not only described as distinct species, but also even separated as genera and finally in a family "Macristiidae" which was allied with various Protacanthopterygii (sensu lato), but the initial assessment - which found "Macristium" to resemble the deepwater lizardfishes (Bathysauridae) in some details - was not far off the mark: "Macristium" species are larvae of Bathysaurus, while the supposed other "macristiids", "Macristiella" species are larvae of the deepsea tripodfish Bathytyphlops.
Pure retrograde amnesia (PRA) refers to the behavioral syndrome that is characterized by the inability to retrieve remote information in the face of a normal ability to learn new information, with no other ecological or psychometric evidence of cognitive impairment. It should not be confused with brief periods of peritraumatic amnesia that are common in mild concussive head traumas. The findings of pure retrograde amnesia have helped form the dissociation between mechanisms for RA and AA. Several studies have found numerous causes for PRA like vascular diseases, head traumas ranging from mild to severe, encephalitis, as well as purely psychological conditions and totally unidentifiable etiologies. Most people who suffer from PRA can function normally and learn new information A pure form of RA is rare as most cases of RA co-occur with AA. A famous example is that of patient ML. The patient's MRI revealed damage to the right ventral frontal cortex and underlying white matter, including the uncinate fasciculus, a band of fibers previously thought to mediate retrieval of specific events from one's personal past.
