Stylopharyngeus muscle

Dr Owen Kang et al.

The stylopharyngeus is a muscle of the head and neck, and one of the inner longitudinal muscles of the pharynx.

Origin

It originates from the medial aspect of the styloid process base of the temporal bone.

Insertion

It courses inferiorly adjacent to the pharynx, passing between the superior and middle constrictor muscles of the pharynx. A few fibres merge with the lateral glossoepiglottic fold and the constrictor muscles. Other fibres join the palatopharyngeus muscle to attach onto the posterior border of the thyroid cartilage.

The muscle receives motor innervation from the glossopharyngeal nerve (CN IX).
