It is an exception in that it is innervated by the superior laryngeal nerve from XN X all other larynx muscles are innervated by the inferior laryngeal nerve.

8

CN 7 Pre parotid portion

11

The geniohyoid and thyrohyoid as well as the superior belly of the omohyoid and the sternothyroid.

"The Good Stern wOmon"

16

What parasympathetics travel first at the edinger wesfal nucleus?

Edinger wesfall nucleus carries parasympathetics on CN III to the eye via the ciliary ganlgion allowing for pupillary constriction (sphincter)

17

What parasympathetics travel through the superior salvitory nucleus?

CN 7 goes to the pterygopalantine ganlgion and ultimately transverses to the lacrimal glands.

18

What parasympathetics travel through the inferior salvitory nucleus?

CN9 carrries this info to the otic ganglion and auriculo temporal nerve to the parotid gland.

19

How does parasympathetic supply get to the submandibular gland?

CN7 travels to chorda tympani and then hooks onto the submandibular ganglion.
