Cranial autonomics Flashcards
what classification refers to PNS or SNS (autonomic) nervation
GVE (visceromotor function)
what are the CN that run with PNS
3, 7, 9, 10
what are the nuclei associated with 3, 7, 9, 10
3- Edinger-Westphal
7- superior salivatory
9- inferior salivatory
10-Dorsal vagus
- ESID [ east side is dope ]
what does SLUDD stand for
salivation, lacrimation, urination, defection, digestion
PNS from CNs function
what nerves exit/enter the superior orbital fissure
3, 4, 5 (V1), 6
*3-6
what nerve exits the foramen rotundum
5 (v2)
what nerve exits the foramen ovale
5 (v3)
what nerves exit the internal acoustic meatus
7-8
what is the SNS of concern ? where does it synapse
deep petrosal N.
synapses in the superior cervical ganglion
-joins greater petrosal N. of C7 and goes to blood vessels and sweat glands of nasal area
all postganglionic PNS fiber piggy back on ___ nerve to arrive at their structure
trigeminal N.
what is Horners syndrome
-many causes (like extra ribs, etc)
-causes absence of SNS functions to same side
-PAM HORNER (ptosis, anhidrosis, miosis)
miosus= pupil constricting
anihidrosis= no sweating
what branches of V1 piggy back PNS
- lacrimal n.s
2. short ciliary n.s [from nasociliary] (to ciliary muscles and sphincter papillae)
what branches of V2 piggy backs PNS
- zygomatic goes to lacrimal gland
- greater and lesser palatine goes to hard/soft palate
- posterior superior nasal goes to nasal cavity
what branches of V3 does PNS piggy back
- lingual N. (submandibular/sublingual salivary glands)
2. auriculotemporal (to parotid gland)
what are the ganglions associated with 3, 7, 9, 10 and V1, V2, V3
3- ciliary (v1)
7- pterygopalatine (v2) and submandibular (v3)
9-otic
10-none
path of CN 3 PNS division
edinger westphal nucleus to ciliary ganglion to innervate constrictor pupillae M . and ciliary muscles
(from eye accommodation) joining V1 short ciliary nerves
what nerves run in the cavernous sinus
ophthalmic N. (v1)
carotid plexus
oculomotor N. (CN 3)
3, 4, 5, 6
chorda tympani piggy backs on ____
lingual N. to go to submandibular and sublingual glands
desribe the pathway to the lacrimal glands
CN 7 gives off branch called greater petrosal N. at the geniculate ganglion. it then joins deep personal N. are the foramen lucerum and makes the nerve of the pterygoid canal. it travels through the canal into the pterygopalatine fossa where it synapses in pterygopalatine ganglion and innervate lacrimal glands with zygomatic branch of V2 and lacrimal nerve of V1
describe the pathway to submandibular and sublingual glands
CN7 gives off a branch called the chorda tympani just before the stylomastoid foramen. it crosses the tympanic cavity and passes through the petrotympanic fissures to join the lingual N. (v3) in infratemporal fossa. then the PNS synapses in the submandibular ganglion and follows arteries to the glands
describe the pathway to the parotid gland
CN 9 gives off the tympanic nerve which exits the jugular foramen and enters the middle ear via tympanic canaliculus where it forms the tympanic plexus. lesser petrosal nerves arise from the plexus and penetrate roof of tympanic cavity to enter middle cranial fossa and leave through the foramen ovale. PNS synapse in otic ganglion and go to parotid with branches of auriculotoemporal (v3)
what nerves supply SVE fibers (to motor innervation to muscles from pharyngeal arches ) and what arch do they correspond to ?
5- trigeminal - arch 1
7- facial - arch 2
9- glossopharyngeal - arch 3
10- vagus- arch 4 and 6
