Structure
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
The superior longitudinal muscle of the tongue is supplied by the hypoglossal nerve (CN XII).[2]
Function
The superior longitudinal muscle of the tongue works with the other intrinsic muscles to move the tongue.[1]
