Anatomical terms of muscle

The inferior longitudinal muscle of tongue is a narrow band situated on the under surface of the tongue between the genioglossus and hyoglossus.

Course

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 the Styloglossus.

Movement of material through the GI tract is dependent upon the coordinated activity of the longitudinal and smooth muscle of the gut.
