1

four parts of internal carotid

carvical part, petrous part, cavernous part, cerebral part

2

branches that come from the cervical part

none

3

branches from petrous part

caroticotympanic a
artery of pterygoid canal

4

branches from the cavernous part (this may not be very important)

inf hypophysial
trigeminal ganglion branch
neural b
cavernous sinus b
meningeal b
marginal tentorial
basal tentorial

5

branches of cerebral part

ant choroidal
middle cerebral
anterior cerebral
opthalmic
superior hypophysial

6

parts of anterior cerebral

pre communicating - supplies optic areas
post communicating - anterior caudate nuc, putament, front pole area
pericallosal - leg/foot motor/sensory cortices

7

parts of middle cerebral

sphenoidal segment - internal capsule, striate body, lentiform nuc, thalmus
insular segement - insula
opercular segment - operculum
terminal or cortical - speech area/boca and wernicke

8

the vertebral artery has 3 branches before forming the basilar artery

posterior inferior cerebellar
posterior spinal
anterior spinal

9

basilar branches

(moving post to ant)

labarinthine
pontine
superior cerebellar

10

posterior cerebral artery

pre communicating

terminal/cortical segment

11

the pre communicating branch of the pca has what parts/functions

posteromedial - supplies post medial part of midbrain

12

the post communicating branch of the pca has what parts/functions

post lateral - post lateral part of brain
post medial choroidal - choroid plex of 3rd ventrical
post lateral choroidal - choroid plexus of lateral ventricals
