A

stylopharyngeus, as it runs styloid process to thyroid cartilage through the gap between superior and middle constrictor muscles

168
Q

What are the side borders of the piriform recess?

A

thyroid cartilage laterally and cricoid cartilage medially

169
Q

What is the first branch of cranial nerve IX and what does it carry?

A

tympanic nerve, carrying PS fibers to the otic ganglion (to parotid gland) and GSA from tympanic cavity

170
Q

Describe the superior and inferior sensory ganglia.

A

they are a set of paired ganglia for each nerves IX and X

171
Q

What nerve innervates the stylopharyngeus muscle?

A

IX, glossopharyngeal; a brachiomeric muscle

172
Q

Cranial nerve IX afferents carry sensation from what?
