What is the common insertion for all of the constrictor muscles

Pharyngeal Raphe

4

What is the common nerve innervation of the constrictor muscles?

Vagus nerve (CN X) via the pharyngeal plexus

Which constrictor muscle has fibers that will interweave with the muscle fibers of the tongue?

Superior Constrictor

7

What is the specialized band of muscle fibers formed by the superior constrictor to help seal the pharyngeal isthmus during swallowing?

Palatopharyngeal Sphincter

8

What atre the muscles of the longitudinal layer of the pahyranx?
