Human mouth. In human anatomy, the mouth is the first portion of the alimentary canal that receives food and produces saliva. [ 2] 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 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. In tetrapod vertebrates, the mouth is bounded on the outside ...
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]
Fauces (throat) 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] It is a narrow passage between the ...
The pharynx ( pl.: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs respectively). It is found in vertebrates and invertebrates, though its structure varies across species. The pharynx carries food to the esophagus and air to the larynx.
Sagittal section of nose mouth, pharynx, and larynx. (Frenulum linguae is the topmost label at right.) 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 .
Palate. Head and neck. The palate ( / ˈpælɪt /) is the roof of the mouth in humans and other mammals. It separates the oral cavity from the nasal cavity. [1] A similar structure is found in crocodilians, but in most other tetrapods, the oral and nasal cavities are not truly separated. The palate is divided into two parts, the anterior, bony ...
Dissection, showing salivary glands of right side. (Parotid duct visible at center.) The parotid duct or Stensen duct is a salivary duct. It is the route that saliva takes from the major salivary gland, the parotid gland, into the mouth. [ 1] It opens into the mouth opposite the second upper molar tooth .
