The anterior tongue (or oral part) is the portion of the tongue in front of the terminal sulcus. The anterior tongue is roughly two-thirds the length of the tongue.
At the apex, thin and narrow, it is directed forward against the lingual surfaces of the lower incisor teeth.
It is derived primarily from the first pharyngeal arch.
In phonetics and phonology, a distinction is made between the tip of the tongue and the blade (the portion just behind the tip). Sounds made with the tongue tip are said to be apical, while those made with the tongue blade are said to be laminal.
