Constrictor Pharyngis Superior
Abstract
Because a considerable degree of independence may exist between the bundles of fibers coming from different areas of the line of origin, this muscle has been described as consisting of various parts designated pterygopharyngeus, buccopharyngeus, mylopharyngeus, and glossopharyngeus. Frequently, a bundle of fibers arises from the basilar portion of the occipital bone, or even from the inferior surface of the petrous portion of the temporal bone or the spine of the sphenoid, and passes downward to be inserted along with palatopharyngeus.

The salpingopharyngeus is a bundle that arises from the cartilaginous portion of the eustachian tube (auditory tube) and inserts with palatopharyngeus with the remainder of the superior constrictor.
