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.
The term "tip of the tongue" is borrowed from colloquial usage, [2] and possibly a calque from the French phrase avoir le mot sur le bout de la langue ("having the word on the tip of the tongue"). The tip of the tongue phenomenon was first described as a psychological phenomenon in the text The Principles of Psychology by William James (1890 ...
At the tip of the tongue, these rows become more transverse. [2] Histologically, they are made up of irregular connective tissue cores with a keratin–containing epithelium which has fine secondary threads. [2] Heavy keratinization of filiform papillae, occurring for instance in cats, gives the tongue a roughness that is characteristic of ...
Anterior lingual glands (also called apical glands) are deeply placed seromucous glands that are located near the tip of the tongue on each side of the frenulum linguae.They are found on the under surface of the apex of the tongue, and are covered by a bundle of muscular fibers derived from the styloglossus and longitudinalis inferior.
The epiglottic valleculae are paired spaces between the root of the tongue and anterior surface of the epiglottis. Each vallecula is bordered medially by the median glossoepiglottic fold and laterally by the lateral glossoepiglottic fold. The valleculae can collect saliva to prevent initiation of the swallowing reflex.
The tongue is only one of the 10 ways you can see disease written all over your face. There are a whole host of other reasons for bumps on the tongue. Bumps on the tongue come in many other varieties.
Coronal consonants are made with the tip or blade of the tongue and, because of the agility of the front of the tongue, represent a variety not only in place but in the posture of the tongue. The coronal places of articulation represent the areas of the mouth where the tongue contacts or makes a constriction, and include dental, alveolar, and ...
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.
