The superior longitudinal muscle of tongue or superior lingualis is a thin layer of oblique and longitudinal fibers immediately underlying the mucous membrane on the dorsum of the tongue.
Structure
[edit]The superior longitudinal muscle of the tongue is one of the intrinsic muscles of the tongue.[1] It arises from the submucous fibrous layer close to the epiglottis and from the median fibrous septum, and runs forward to the edges of the tongue.
Nerve supply
[edit]The superior longitudinal muscle of the tongue is supplied by the hypoglossal nerve (CN XII).[2]
Function
[edit]The superior longitudinal muscle of the tongue works with the other intrinsic muscles to move the tongue.[1]
