Etymology
In English this muscle’s name is the muscle of the roof of the mouth and the tongue. The word palatoglossus can be divided into the Greek words palatum meaning “roof of the mouth” and glossa meaning “tongue.”
Origin
Inferior surface of the palatine aponeurosis
Insertion
Lateral aspect and dorsal surface of the tongue forming the palatoglossal arch at the oral opening into the pharynx
Action
Elevates the back of the tongue and narrows the junction between the oral cavity and the pharynx.
Nerve supply
Vagus nerve (Cranial nerve X)
Blood supply
The ascending palatine artery, which is one of the cervical branches of the facial artery, supplies the muscle along with a somewhat variable branch of pharyngeal arteries from the external carotid artery. It also receives blood from the greater palatine artery, a terminal branch of the descending palatine artery from the third part of the maxillary artery.
