Latin muscle parts
Branchial arch muscle – fourth arch (Muscle of soft palate and fauces or Tongue muscle)
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.”
Inferior surface of the palatine aponeurosis
Lateral aspect and dorsal surface of the tongue forming the palatoglossal arch at the oral opening into the pharynx
Elevates the back of the tongue and narrows the junction between the oral cavity and the pharynx.
Vagus nerve (Cranial nerve X)
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.
