Oculomotor nerve
-the course of the oculomotor nerve through the ... sinus where it picks up post-ganglionic sympathetic fibers
-the division of the nerve into a superior division and inferior division
the blink reflex involves what nerves and in what direction? (in and/or out)
-CN V1 (sensory) - in

-CN 7 (motor) - out
the nasociliary nerve is a branch of ...

it crosses the ... nerve going lateral to medial
V1 - opthalmic branch of trigem.

what nerve gives off the long ciliary nerves?
nasociliary nerve
the long ciliary nerve contains what types of nerves and where are the origins of the cell bodies located?
-sensory - trigeminal ganglion
-sympathetics - superior cervical ganglion
the short ciliary nerve contains what type of nerves and where are the origins of the cell bodies located?
-sensory - trigeminal ganglion
-sympathetics from sup. cerv. ganglion
-parasympathetics from the ciliary ganglion
Ciliary ganglion:
-note its location between ... muscle and ... nerve
-the short ciliary nerves run from the ciliary ganglion to the back of the eye. Contains postganglionic parasympathetics innervating the ciliary and ... pupillae muscles, and sensory fibers from the ...
-parasympathetics are concerned with pupillary ... and ...
-lateral rectus and optic n.
-constriction and accomodation
what are these?
-branches of the nasociliary nerve of the opthalmic (V1). Contain postganglionic sympathetic fibers traveling to the dilator pupillae, as well as sensory fibers from the cornea.
long ciliary nerves
what are these?
-branches arising from ciliary ganglion carrying postganglionic parasympathetic fibers, sensory fibers, and postganglionic sympathetic fibers
short ciliary nerves
Chorda tympani:
-branch of the ... nerve arising near the middle ear in the temporal bone. After running across the tympanic membrane it exits the skull through the ...
-contains ... fibers from the anterior 2/3rds of the tongue
-contains preganglionic parasympathetic fibers traveling to the ...
petrotympanic fissure
submandibular ganglion
what is this?
-sits on hyoglossus, just above the submandibular gland, suspended from the lingual nerve by several filaments
submandibular ganglion
Greater petrosal nerve:
-branch of the ... nerve. it leaves the temporal bone by a small hole (...) in the middle cranial fossa and runs beneath the dura and trigeminal ganglion to the foramen lacerum. Contains preganglionics going to the ... and taste fibers from the palate
-hiatus for the greater petrosal nerve
-pterygopalatine ganglion
what is this?
-in life, it's filled with fibrocartilage
-nothing passes through it
-internal carotid artery and greater petrosal nerve cross it.
-in the foramen, the GPN meets the deep petrosal nerve to form the nerve of the pterygoid canal. The deep petrosal nerve consists of post ganglionic sympathetic fibers
foramen lacerum
pterygoid canal
-connects foramen lacerum with the ... where the ganglion is located
-entrance is located at the base of the ... of the sphenoid
-contains the nerve of the pterygoid canal which contains preganglionic ... and postganglionic ...
pterygopalatine fossa
pterygoid process
maxillary nerve:

-leaves the pterygopalatine fossa through the ... where it continues to the face as ... nerve
foramen rotundum
inferior orbital fissure
infraorbital nerve
what is this?
-trauma to skull - nerves are torn.
-during regeneration, aberrant connections develop between greater and lesser petrosal nerves.
-instead of salivating the patient cries.
crocodile tears
what is this?
-trauma and damage to autonomic fibers to parotid
-aberrant regeneration results in parasympathetics innervating the sweat glands and blood vessels.
-red shading along parotid gland
frey syndrome
Danger area of the face:
-Bordered by upper lip, lateral nose, lateral corner of eye.
-squeezing pimples and tampering with boils in this region should be avoided since the area may be drained by the ... veins which leads directly into ... sinus
what 5 nerves are located in the caverous sinus?
Cavernous sinus:
-covered by the meningeal layer of dura, lying against the body of the sphenoid just lateral to the sella turcica. Receives blood from the orbit, via the inferior and superior opthalmic veins, from the pterygoid plexus and from the brain via cerebral veins. it is drained by superior and inferior petrosal sinuses. CN # and ... lie in the sinus. CNs ...... are in the lateral wall. Infection here will lead to problems with eye muscles.
