Autonomics of Head and Neck: Key Terms & Definitions for Biology

all autonomic ganglia in the head are what? what are their names?

parasympathetic!

C: Ciliary

O: Otic

P: Pterygopalatine

S: Submandibular

real order is CPSO just FYI

preganglionic parasympathetic fibers reach their target ganglia via branches of which cranial nerves?

III (oculomotor), VII (facial), IX (glossopharyngeal)

postganglionic parasympathetic fibers reach their end organs by hitch-hiking along branches of what?

CN V: Trigeminal

preganglionic sympathetic fibers arise from what vertebral levels?

T1-T4

postganglionic sympathetic fibers arise from where?

superior cervical ganglion

the postganglionic sympathetic fibers arising from superior cervical ganglion reach their end organs via branches of what?

internal and external carotid arteries

T1-T4 is sympathetic supply to where?

Head/neck

CN III (oculomotor) uses the ciliary ganglion to do what actions?

Sympathetics: dilate pupils

Parasympathetics: constricts pupils

CN VII (facial nerve) uses the pterygopalatine ganglion to reach what area?

the lacrimal gland + palate and above

CN VII (facial nerve) uses the submandibular ganglia to reach what area?

sublingual gland and submandibular gland + floor of mouth

CN IX (glossopharyngeal) uses the otic ganglion to reach what area?

parotid gland + vestibule of mouth

CN III uses ciliary ganglion and travels with what branch of CN V?

V1

CN VII uses pterygopalatine ganglion and travels with what branch of CN V?

V2

CN VII uses submandibular ganglion and travels with what branch of CN V?

V3

CN XI uses otic ganglion and travels with what branch of CN V?

V3
