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.
Anatomical terminology. [ edit on Wikidata] The lips are a horizontal pair of soft appendages attached to the jaws and are the most visible part of the mouth of many animals, including humans. [ 1] Vertebrate lips are soft, movable and serve to facilitate the ingestion of food (e.g. suckling and gulping) and the articulation of sound and speech.
Anatomical terminology. [ edit on Wikidata] The commissure is the corner of the mouth, where the vermillion border of the superior labium (upper lip) meets that of the inferior labium (lower lip). The commissure is important in facial appearance, particularly during some functions, including smiling. As such it is of interest to dental surgeons.
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]
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 ...
Philtrum. The philtrum ( Latin: philtrum from Ancient Greek φίλτρον phíltron, lit. "love charm" [ 2]) or medial cleft is a vertical indentation in the middle area of the upper lip, common to therian mammals, extending in humans from the nasal septum to the tubercle of the upper lip. Together with a glandular rhinarium and slit-like ...
Orbicularis oris muscle. Inferior labial artery and superior labial artery. It is sometimes known as the kissing muscle[ 1] because it is used to pucker the lips. In human anatomy, the orbicularis oris muscle is a complex of muscles in the lips that encircles the mouth. [ 2] It is not a true sphincter, as was once thought, as it is actually ...
Labial glands. The labial glands are minor salivary glands situated between the mucous membrane and the orbicularis oris around the orifice of the mouth . They are circular in form, and about the size of small peas; their ducts open by minute orifices upon the mucous membrane. Like the parotid and buccal glands, the labial glands are innervated ...
