Cranial Autonomics Flashcards
What are the 4 parasympathetic nuclei in the brain and their associated CNs?
- Edinger-Westphal Nucleus CNIII
- Superior Salivatory Nucleus CNVII
- Inferior Salivatory Nucleus CNIX
- Dorsal Vagal Nucleus CNX
Cribiform plate
CN1
Optic canal
CNII
Superior orbital fissure
CNIII, CNIV, CNV1, and CNVI
Foramen rotundum
CNV2
Foramen ovale
CNV3
Foramen lacerum
joins with deep petrosal N. to form nerve of pterygoid canal
What is the only sympathetic cranial nerve we must know?
Deep petrosal N.
Internal acoustic meatus
CNVII and CNVIII
Jugular foramen
CNIX, CNX, CNXI
Hypoglossal canal
CNXII
ophthalmic division of trigeminal
CNV1
maxillary division of trigeminal
CNV2
mandibular division of trigeminal
CNV3
Where do all postganglionic sympathetic fibers in the head come from?
superior cervical ganglion of sympathetic trunk
What are the 4 parasympathetic ganglion
ciliary, pterygopalatine, otic, and submandibular
How do postganglionic parasympathetic nerve fibers travel in the brain?
jump onto a branch of the trigeminal nerve (CNV)
Horner’s Syndrome
Ptosis
Anhydrosis
Miosis (pupil constriction)
lack of sympathetics!
what parasympathetics piggyback on V2 of trigeminal?
zygomatic (to lacrimal gland), greater/lesser palatine, and posterior superior nasal
what parasympathetics piggyback on V3 of trigeminal?
lingual and auriculotemporal (to parotid)
CNIII tract
Edinger Westphal nucleus - ciliary ganglion - parasympathetic innervation to constrictor pupillae and ciliary muscles
CNIII tract
Edinger Westphal nucleus - ciliary ganglion - parasympathetic innervation to constrictor pupillae and ciliary muscles
What CN travels with auriculotemporal to the parotid?
glossopharyngeal CNIX
What CN travels with zygomatic branch (V2) and lacrimal n. (V1) to the lacrimal gland?
Facial Nerve CNVII
What CN travels with the lingual N. (CNV3) in the infratemporal fossa?
Facial Nerve CNVII
