Q

What are the 4 parasympathetic ganglion

A

ciliary, pterygopalatine, otic, and submandibular

17
Q

How do postganglionic parasympathetic nerve fibers travel in the brain?

A

jump onto a branch of the trigeminal nerve (CNV)

18
Q

Horner’s Syndrome

A

Ptosis
Anhydrosis
Miosis (pupil constriction)
lack of sympathetics!

19
Q

what parasympathetics piggyback on V2 of trigeminal?

A

zygomatic (to lacrimal gland), greater/lesser palatine, and posterior superior nasal

20
Q

what parasympathetics piggyback on V3 of trigeminal?

A

lingual and auriculotemporal (to parotid)

21
Q

CNIII tract

A

Edinger Westphal nucleus - ciliary ganglion - parasympathetic innervation to constrictor pupillae and ciliary muscles

22
Q

CNIII tract
