Salpingopharyngeal muscle

Salpingopharyngeal muscle
origin
Eustachi tube
approach
with the palatopharyngeus muscle on the pharynx wall and thyroid cartilage
function
Lifting of the throat and larynx ; Pull the torus tubarius to equalize the pressure in the middle ear
Innervation
Vagus nerve

The salpingopharyngeal muscle ( Latin for "tube-throat muscle") is a skeletal muscle of the head. It arises from the lower part of the cartilage of the Eustachian tube ( Tuba auditiva ) and runs downwards, where it joins the posterior strand of the palatopharyngeal muscle . The muscle lifts the throat and larynx when swallowing . In addition, it tightens the salpingopharyngeal plica and enables the trachea to be tightly closed by the epiglottis. The innervation occurs through the pharyngeal plexus ( pharyngeal plexus ), mainly via fibers of the vagus nerve ( cranial nerve X).
