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 .
The tongue is a muscular organ in the mouth of a typical tetrapod. It manipulates food for chewing and swallowing as part of the digestive process, and is the primary organ of taste. The tongue's upper surface (dorsum) is covered by taste buds housed in numerous lingual papillae. It is sensitive and kept moist by saliva and is richly supplied ...
Prominent fringed fimbriated folds. The fimbriated fold of tongue, also plica fimbriata, is a slight fold of the mucous membrane on the underside of the tongue which runs laterally on either side of the frenulum. The free edge of the fimbriated fold occasionally exhibits a series of fringe-like processes. ( Fimbria is Latin for fringe ).
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.
Frenulum. Anatomy of the human mouth, including the frenulum of the tongue. A frenulum / ˈfrɛnjʊləm / or frenum / ˈfriːnəm / ( pl.: frenula or frena, from the Latin frēnulum, "little bridle", the diminutive of frēnum [1]) is a small fold of tissue that secures the motion of a mobile organ in the body .
Hyoid bone. The hyoid bone ( lingual bone or tongue-bone) ( / ˈhaɪɔɪd / [ 2][ 3]) is a horseshoe-shaped bone situated in the anterior midline of the neck between the chin and the thyroid cartilage. At rest, it lies between the base of the mandible and the third cervical vertebra . Unlike other bones, the hyoid is only distantly articulated ...
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.
The alveolar process ( / ælˈviːələr, ˌælviˈoʊlər, ˈælviələr /) [ 1] is the portion of bone containing the tooth sockets on the jaw bones (in humans, the maxilla and the mandible ). The alveolar process is covered by gums within the mouth, terminating roughly along the line of the mandibular canal. Partially comprising compact bone ...
