Q

what separates fas grace and cute

A

posterior median sulcus

Q

Posterior column carry what

A

senior info (proprio, fine touch, disrcrminatve touch, vibration)

Q

where is 4th ventricle

A

over rostal medulla /pns

Q

where does the 4th ventricle open up

A

obey

Q

where does trigmenal nerve emerge from

A

mid pons

Q

where does trigemal sensory ganglion sit

A

floor or middle cranial fossa

Q

three branches of trigeminal

A

ophthalmic
maxillary
mandibular

where does ophthalmic bench exit through

superior orbital fissure

where does maxillary branch exit through

foramen rotunda

where does mandibular exit through

foramen oval

main sensory nerve of head

trigmenal

whats sense does trigeminal carry

pain, temp disc touch vibration proprio

do all divisons of trigmeanl Carry the same

yes

what does mandibular division do thats special

motor mm mastication

what does trigemal carry

afferent sensory (GSA) efferent motor (SVE)

whats GSA for trigeminal

general sensation from head and neck

whats SVE for tigmenal

mm for mastication

wheres trigmenal tract on caudal medulla

top corners

where tract extend to

medulla to pons

wheres tri nucleus

under top right corners

chief nucleus trigmenal where

mid pons

whats nucleus on trigmenal do

touch vibration

theres motor nuclus of trigmeanl

mid pons

wheres mesencephalic nucleus of trigeminal

caudal midbrain

whats mesencephalic do

proprioception from mm of mastication

whats on the inside nuclues or tract

nucleus

top down wheres uncle of chief mesencephalic and motor

cheif, mesencepahic | motor
