It is a thin, paired muscle, located on either side of the oropharynx. Attachments: Originates from the styloid process of the temporal bone and inserts onto the lateral aspect of the tongue. Function: Retraction and elevation of the tongue. Innervation: Hypoglossal nerve. Blood supply: Lingual artery with contributions from the tonsillar artery.

Learn More Frequent questions What is the styloglossus muscle? The styloglossus is an extrinsic muscle of the tongue that aids in its movement. It is a paired muscle situated on either side of the oropharynx. Where does the styloglossus muscle originate and insert? The styloglossus muscle originates from the styloid process of the temporal bone and inserts onto the lateral aspect of the tongue. This positioning allows it to effectively contribute to tongue movement. What is the primary function of the styloglossus? The primary function of the styloglossus muscle is to facilitate the retraction and elevation of the tongue. This action is crucial for various oral functions, including swallowing and speech. Which nerve innervates the styloglossus muscle? The styloglossus muscle is innervated by the hypoglossal nerve. This nerve is essential for controlling the movements of the tongue. What is the blood supply to the styloglossus muscle? The blood supply to the styloglossus muscle primarily comes from the lingual artery, with additional contributions from the tonsillar artery. This vascularisation supports the muscle's function and health. Rate This Article
