The inferior longitudinal muscle of tongue is an intrinsic muscle of the tongue. It is situated on the under surface of the tongue between the genioglossus and hyoglossus. It helps to move the tongue.
Structure
The inferior longitudinal muscle of the tongue is an intrinsic muscle of the tongue.[1] It extends from the root to the apex of the tongue. Behind, some of its fibers are connected with the body of the hyoid bone. In front, it blends with the fibers of styloglossus.
Nerve supply
The inferior longitudinal muscle of the tongue is supplied by the hypoglossal nerve (CN XII).[2]
Function
The inferior longitudinal muscle of the tongue moves the tongue.[1] Movement of material through the pharynx is dependent upon the coordinated activity of the longitudinal and smooth muscle of the gut.
