Synonym: glossopalatinus muscle

Definition

The palatoglossus muscle is a small muscle that forms the palatopharyngeal arch and is part of the palatal musculature.

Some sources also classify it as part of the external tongue musculature.

Course

Origin

The palatoglossus muscle originates from the palatal aponeurosis of the soft palate. Its fibers are closely associated with those of the muscle on the opposite side at the midline.

Attachment

The fibers of the palatoglossus muscle run laterally and downward, passing in front of the palatine tonsil. They then merge with the fibers of the tongue muscles, inserting into the lateral edges of the tongue and, with some fibers, into the posterior part of the tongue. Deeper within the tongue, some fibers intermingle with those of the transverse muscle of the tongue.

Innervation

The palatoglossus muscle is innervated by the pharyngeal plexus, which is primarily composed of fibers from the vagus nerve (cranial nerve X) or, according to some sources, the glossopharyngeal nerve (cranial nerve IX).

Function

The palatoglossus muscle plays a role in swallowing by elevating the base of the tongue and narrowing the pharyngeal isthmus, thereby aiding in the closure of the oral cavity during swallowing.

 ===Attachment===
-The fibres of the palatoglossus muscle run laterally and caudally in front of the palatine tonsil (tonsilla palatina) and meet the fibres of the lingual muscles. The muscle inserts into the lateral edge of the tongue and with some fibres into the back of the tongue. In the depth of the tongue body, some fibres intermingle with the fibres of the transversus linguae muscle.
