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
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
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.

- PURPOSE: The purpose of the study was to determine the relationships between the extracranial glossopharyngeal (IX) nerve and the muscles of the styloid diaphragm. In humans, the IX nerve is a hidden retrostyloid nerve which plays a critical role notably in swallowing and has to be preserved during

- The fascial configuration in the suprahyoid parapharyngeal space was evaluated using semiserial sagittal sections of 15 late-stage human fetal heads. The prevertebral fascia covered the longus colli, longus capitis, and rectus capitis lateralis muscles, but was most evident along the longus colli mu

The aim of this study was to provide anatomical confirmation of the muscular constraints of T4a classification of oral tongue tumours.METHODS
