It may occur in the skin, subcutaneous tissues and mucous membranes of oral cavities and lips as well as in the liver, spleen and kidneys. While this birthmark may be alarming in appearance, physicians generally counsel that it be left to disappear on its own, unless it is in the way of vision or blocking the nostrils.

Jaw muscles do not display very prominent changes in muscular tissue with age in healthy elderly, as their oral cavities are in constant motor movement (i.e.: performing tasks such as talking and chewing etc.). This motion delays the decrease in lean body mass and aids protein retention that comes with age, preventing the muscular tissues from wearing and tearing.

Members of the genus Capnocytophaga are found in the oral cavities of humans and animals. Most of these species are not found in humans. C. canimorsus is a commensal bacterium found in dogs and cats; it is not a member of the normal microbiota of humans. About 26% of dogs carry these commensal bacteria in their mouths.

Cryptobacterium curtum is asaccharolytic and unreactive in many of the conventional biochemical tests. Instead, it is able to degrade arginine and other amino acids found in oral cavities by using the arginine deiminase pathway. This bacterium is able to degrade arginine and produce substantial amounts of citrulline, ornithine and ammonia. Arginine and citrulline support the growth and reproduction of C. curtum.

Candida dubliniensis is a fungal opportunistic pathogen originally isolated from AIDS patients. It is also occasionally isolated from immunocompetent individuals. It is a dimorphic yeast of the genus Candida, very closely related to Candida albicans but forming a distinct phylogenetic cluster in DNA fingerprinting. It is most commonly isolated from oral cavities, and is also occasionally found in other anatomical sites.

Capnocytophaga spp. can be resistant to third-generation cephalosporins, but remain susceptible to imipenem, cefoxitin, and amoxicillin combined with clavulanic acid. Although resistant strains are most frequently isolated in oral cavities, their prevalence is worrying, (Jolivet-Gougeon et al., 2008; Sixou et al., 2006). The CfxA broad spectrum beta- lactamases (CfxA, CfxA2 and CfxA3) belong to the group 2e of Bush classification.

The candidate division SR1 and gracilibacteria code (translation table 25) is used in two groups of (so far) uncultivated bacteria found in marine and fresh-water environments and in the intestines and oral cavities of mammals among others. The difference to the standard and the bacterial code is that UGA represents an additional glycine codon and does not code for termination.

The most common adverse effects associated with paromomycin sulfate are abdominal cramps, diarrhea, heartburn, nausea, and vomiting. Long-term use of paromomycin increases the risk for bacterial or fungal infection. Signs of overgrowth include white patches in the oral cavities. Other less common adverse events include myasthenia gravis, kidney damage, enterocolitis, malabsorption syndrome, eosinophilia, headache, hearing loss, ringing in the ear, itching, severe dizziness, and pancreatitis.

S. ferus was originally isolated from the oral cavity wild rats who were living in sugar cane fields and eating a high sucrose diet The species name ferus, meaning wild, refers to their association with these animals. More recently the strain has also been isolated from the nasal and oral cavities of pigs. The species has not been identified in any other host organisms.

Dogs may be able to detect explosives in rectal, vaginal, or oral cavities, but not implanted explosives. Dogs can also detect traces of explosives if the person has been in contact with them before implantation. However, they are subject to exhaustion. Additionally, issues exist concerning canine training procedures, as most bomb dogs are trained to ‘alert’ on items and not on individuals for detecting explosive material residues.

"Francis Bacon". South Bank Show. BBC documentary, first aired 9 June 1985 His interest in the mouth was further stimulated by a medical textbook of diseased oral cavities bought in a second-hand bookshop, which he kept in his studio and to which he often referred.Schmied, 18 The glass cage might imply a vacuum that the figure's voice is unable to escape; as if it is screaming in silence.

All members of this genus, including M. orale, inhabit a wide range of mammalian hosts. Though M. orale usually exists as a commensal in human oral cavities, it is an opputunistic pathogen and will cause illness in human hosts when conditions are right. Due to their small genome size and parasitic lifecycle, they lack many non-essential biosynthetic pathways in their metabolism. These include those for cell wall synthesis as well as purine synthesis.

A major cause of dysgeusia is chemotherapy for cancer. Chemotherapy often induces damage to the oral cavity, resulting in oral mucositis, oral infection, and salivary gland dysfunction. Oral mucositis consists of inflammation of the mouth, along with sores and ulcers in the tissues. Healthy individuals normally have a diverse range of microbial organisms residing in their oral cavities; however, chemotherapy can permit these typically non-pathogenic agents to cause serious infection, which may result in a decrease in saliva.

Protocatechuic acid (PCA) is antioxidant and anti-inflammatory. PCA extracted from Hibiscus sabdariffa protected against chemically induced liver toxicity in vivo. In vitro testing documented antioxidant and anti-inflammatory activity of PCA, while liver protection in vivo was measured by chemical markers and histological assessment. PCA has been reported to induce apoptosis of human leukemia cells, as well as malignant HSG1 cells taken from human oral cavities, but PCA was found to have mixed effects on TPA-induced mouse skin tumours.

Bifidobacterium dentium is a species of bacteria in the genus Bifidobacterium, branched anaerobic bacteria from the Bifidobacteriaceae family. B. dentium is a source of anaerobic infections, and is also tracked in polluted water to trace the source of fecal contamination. Scientists have shown that B. dentium can cause tooth decay in humans. Due to its high tolerance of the acidic environments reached by the human mouth (pH 4.5), B. dentium can sustain growth in the oral cavities, cause harm to the teeth, and break down sugars.

Nasal and oral cavities with the velopharyngeal sphincter highlighted in blue The palate comprises two parts, the hard palate (palatum durum) and the soft palate (palatum molle), which is connected to the uvula. The movements of the soft palate and the uvula are made possible by the velopharyngeal sphincter. During speech or swallowing, the soft palate lifts against the back throat wall to close the nasal cavity. When producing nasal consonants (such as "m", "n", and "ng"), the soft palate remains relaxed, thereby enabling the air to go through the nose.

P. canis can be found in healthy domesticated, farm-raised, and wild animals, such as dogs, cats, rabbits, horses, sheep, cattle, ferrets, deer, and even California sea lions. The bacteria are normally isolated from the oral cavities and respiratory tracts of these animals. P. canis biotype 1 was shown to secrete a toxin analogous to P. multocida toxin, but its identity is unknown. P. canis is responsible for a number of canine infections, including systemic infection, external otitis, bacterial rhinitis, vertebral osteomyelitis, meningomyelitis (a type of myelitis), bronchopneumonia, tracheitis, paranasal sinus inflammation, and toxicosis.

Mulholland began his career as a consultant for St. Joseph's Hospital in Hamilton, Ontario where he worked on reconstruction of faces and necks where tumors were removed. Mulholland's work in plastic surgery has included reconstructive, trauma, and cancer surgery. He has invented different procedures for each, including transplanting sensate tissue into oral cavities defects after the removal of tongue and jawbone tissue. He also developed the OsteoCutaneous Skin Flap procedure, an auto-transplant procedure where the tibia and skin from the back of the foot is transplanted by re-connecting all the small arteries, veins and nerves using a microscope.

Throughout a large portion of the year the sexes remain separated and only congregate during the mating months; however, other patterns may be described, such as bachelor groups and even mixed groups. In male fallow deer, their low frequency groans are produced by vocal tracts that are of consistent but complex shape. Experimentation showed that vocal production of these groans are dependent on both their nasal and oral cavities. Ruts are characterized by males gaining the best territory possible to increase their odds for mating and are often characterized by the presence of females on stands.

In bacterial physiology, BCATs perform both reactions, forming both α-ketoacids and branched chain amino acids. Bacteria growing on a medium lacking the right amino acid ratios for growth must be able to synthesize branched chain amino acids in order to proliferate. In Streptococcus mutans, the gram-positive bacteria that lives in human oral cavities and is responsible for tooth decay, amino acid biosynthesis/degradation has been found to regulate glycolysis and maintain the internal pH of the cell. This allows the bacteria to survive in the acidic conditions of the human oral cavity from the breakdown of carbohydrates.

The trigeminal lemniscus, also called the trigeminothalamic tract, is composed of the ventral trigeminal tract, and the dorsal trigeminal tract – nerve tracts that convey tactile, pain, and temperature impulses from the skin of the face, the mucous membranes of the nasal and oral cavities, and the eye, as well as proprioceptive information from the facial and masticatory muscles. The trigeminal lemniscus is composed of second order neuronal axons in the brainstem. It carries sensory information from the trigeminal system to the ventral posteromedial (VPM) nucleus of the thalamus. This tract was historically considered a cephalic division of the medial lemniscus due to the close proximity of the two ascending tracts.

Sneezing typically occurs when foreign particles or sufficient external stimulants pass through the nasal hairs to reach the nasal mucosa. This triggers the release of histamines, which irritate the nerve cells in the nose, resulting in signals being sent to the brain to initiate the sneeze through the trigeminal nerve network. The brain then relates this initial signal, activates the pharyngeal and tracheal muscles and creates a large opening of the nasal and oral cavities, resulting in a powerful release of air and bioparticles. The powerful nature of a sneeze is attributed to its involvement of numerous organs of the upper body – it is a reflexive response involving the face, throat, and chest muscles.

A notable exception is the NeXT-based system originally developed and marketed by Trillium Sound Research, a spin-off company of the University of Calgary, where much of the original research was conducted. Following the demise of the various incarnations of NeXT (started by Steve Jobs in the late 1980s and merged with Apple Computer in 1997), the Trillium software was published under the GNU General Public License, with work continuing as gnuspeech. The system, first marketed in 1994, provides full articulatory-based text-to-speech conversion using a waveguide or transmission-line analog of the human oral and nasal tracts controlled by Carré's "distinctive region model". More recent synthesizers, developed by Jorge C. Lucero and colleagues, incorporate models of vocal fold biomechanics, glottal aerodynamics and acoustic wave propagation in the bronqui, traquea, nasal and oral cavities, and thus constitute full systems of physics-based speech simulation.

HRTF filtering effect A head-related transfer function (HRTF), also sometimes known as the anatomical transfer function (ATF), is a response that characterizes how an ear receives a sound from a point in space. As sound strikes the listener, the size and shape of the head, ears, ear canal, density of the head, size and shape of nasal and oral cavities, all transform the sound and affect how it is perceived, boosting some frequencies and attenuating others. Generally speaking, the HRTF boosts frequencies from 2–5 kHz with a primary resonance of +17 dB at 2,700 Hz. But the response curve is more complex than a single bump, affects a broad frequency spectrum, and varies significantly from person to person. A pair of HRTFs for two ears can be used to synthesize a binaural sound that seems to come from a particular point in space.
