The Styloglossus, the shortest and smallest of the three styloid muscles, arises from the anterior and lateral surfaces of the styloid process, near its apex, and from the stylomandibular ligament.
Passing downward and forward between the internal and external carotid arteries, it divides upon the side of the tongue near its dorsal surface, blending with the fibers of the Longitudinalis inferior in front of the Hyoglossus; the other, oblique, overlaps the Hyoglossus and decussates with its fibers.

Innervation [edit]
The styloglossus is innervated by the Hypoglossal nerve (CN XII) like all muscles of the tongue except palatoglossus which is innervated by the Pharyngeal plexus of vagus nerve (CN X).
Action [edit]
The styloglossus draws up the sides of the tongue to create a trough for swallowing. As a pair they also aid in retracting the tongue.
