Stylopharyngeus
Stylopharyngeus
Stylopharyngeus (pronunciation: sti-lo-fa-rin-jee-us) is a muscle in the human body that is part of the pharyngeal musculature.
Etymology
The term "Stylopharyngeus" is derived from the Greek words "stylos" meaning pillar and "pharynx" meaning throat, referring to the muscle's location and function.
Function
The primary function of the Stylopharyngeus is to elevate the pharynx and larynx during swallowing and speech. It is innervated by the glossopharyngeal nerve (cranial nerve IX).
Anatomy
The Stylopharyngeus originates from the medial side of the styloid process of the temporal bone. It descends between the internal carotid artery and the internal jugular vein, and inserts into the posterior border of the thyroid cartilage.
