In human anatomy, the mouth is the first portion of the alimentary canal that receives food and produces saliva. The oral mucosa is the mucous membrane epithelium lining the inside of the mouth. In addition to its primary role as the beginning of the digestive system, the mouth also plays a significant role in communication.
The oral mucosa is the mucous membrane lining the inside of the mouth. It comprises stratified squamous epithelium, termed "oral epithelium", and an underlying connective tissue termed lamina propria. [1] The oral cavity has sometimes been described as a mirror that reflects the health of the individual. [2]
Meth mouth is a colloquial term used to describe severe tooth decay and tooth loss, as well as tooth fracture, acid erosion, and other oral problems that are often symptomatic to extended use of the drug methamphetamine.
A radiographic image is formed by a controlled burst of X-ray radiation which penetrates oral structures at different levels, depending on varying anatomical densities, before striking the film or sensor. Teeth appear lighter because less radiation penetrates them to reach the film.
Mouth. The mouth is the body orifice through which many animals ingest food and vocalize. The body cavity immediately behind the mouth opening, known as the oral cavity (or cavum oris in Latin ), [2] is also the first part of the alimentary canal, which leads to the pharynx and the gullet.
Torus mandibularis seen at axial CT and volume rendering. Torus mandibularis is a bony growth in the mandible along the surface nearest to the tongue. Mandibular tori usually are present near the premolars and above the location on the mandible of the mylohyoid muscle attachment. [1]
Insects have mouthparts that may vary greatly across insect species, as they are adapted to particular modes of feeding. The earliest insects had chewing mouthparts. Most specialisation of mouthparts are for piercing and sucking, and this mode of feeding has evolved a number of times independently.
Human tooth. Image showing incisors and canine teeth, situated in gums above and below. Human teeth function to mechanically break down items of food by cutting and crushing them in preparation for swallowing and digesting. As such, they are considered part of the human digestive system. [1]
The frenulum (or frenum) of the tongue, tongue web, lingual frenulum, frenulum linguae, or fraenulum [1] is a small fold of mucous membrane extending from the floor of the mouth to the midline of the underside of the human tongue .
A view of the fauces through the mouth cavity. The cheeks have been slit transversely and the tongue pulled forward. (Fauces labelled as Isthmus faucium at center right.) The fauces, isthmus of fauces, or the oropharyngeal isthmus is the opening at the back of the mouth into the throat. [1]
