Where is sinus of Morgagni?

In the pharynx, the sinus of Morgagni is the enclosed space between the upper border of the superior pharyngeal constrictor muscle, the base of the skull and the pharyngeal aponeurosis.

Which of the following passes between base of the skull and superior constrictor muscle?

Between the superior constrictor muscle and the skull , the levator palatini muscle, the auditory tube and the ascending palatine artery pass through. Between the superior and middle pharyngeal constrictor muscles, the stylopharyngeus muscle and the glossopharyngeal nerve pass through.

What is sinus of larynx?

What does the pharyngeal plexus innervate?

The pharyngeal plexus provides sensory innervation of the oropharynx and laryngopharynx from CN IX and CN X. (The nasopharynx above the pharyngotympanic tube and the torus tubarius is innervated by CN V2).
