The anterior oral part is the visible part situated at the front and makes up roughly two-thirds the length of the tongue. The posterior pharyngeal part is the part closest to the throat, roughly one-third of its length. These parts differ in terms of their embryological development and nerve supply. The anterior tongue is, at its apex, thin ...
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).
Ankyloglossia, also known as tongue-tie, is a congenital anomaly characterised by an abnormally short lingual frenulum; when severe, the tip of the tongue cannot be protruded beyond the lower incisor teeth. [6] There are two generalized classifications of ankyloglossia, anterior and posterior tongue-ties.
In veterinary anatomy, the term hyoid apparatus is the collective term used to refer to the bones of the tongue—a pair of stylohyoidea, a pair of thyrohyoidea, and unpaired basihyoideum [21] —and associated, upper-gular connective tissues. [22] In humans, the single hyoid bone is an equivalent of the hyoid apparatus. [23]
Lingual papillae, particularly filiform papillae, are thought to increase the surface area of the tongue and to increase the area of contact and friction between the tongue and food. [2] This may increase the tongue's ability to manipulate a bolus of food, and also to position food between the teeth during mastication (chewing) and swallowing.
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.
Anatomy of the human mouth, including the frenulum of the tongue. A frenulum / ˈ f r ɛ n j ʊ l əm / or frenum / ˈ f r iː n əm / (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.
The hyoid apparatus is the collective term used in veterinary anatomy for the bones which suspend the tongue and larynx. [1] It consists of pairs of stylohyoid, thyrohyoid, epihyoid and ceratohyoid bones, and a single basihyoid bone. [2] The hyoid apparatus resembles the shape of a trapeze, [3] or a bent letter "H". [4]
