supplies anterior limb of internal capsule
artery of heubner
Right common carotid artery arises from
Brachiocephalic (in nominate) artery
Left Common Carotid Artery arises from
Directly from aortic arch
Level of bifurcation into external and intracranial artery
Level of C4
Just below the angle of the jaw
Four segments of the MCA
M1 main MCA trunk with deep penetrating vessels and lenticular triage arteries
M2 Sylvian fissure
M3 all cortical branches
M4 over the cortical surface
Occlusion of the artery of heubner may give rise to what kind of aphasia
Transcorticomotor aphasia
T/F
The Lacerum segment of the ICA passes thru the foramen lacerum.
False
DOES NOT PASS THROUGH but LIES OVER the foramen

solitary nucleus of X, and medial lemniscus
arise from the anterior spinal artery
Perforating arteries of the caudal medulla
Supplies the dorsolateral medulla and
the posterior inferior quarter of the
cerebellum
Posterior Inferior Cerebellar artery
supplies the lateral pons and the anterior inferior quarter of the cerebellum
Anterior inferior Cerebellar artery
supply the medial pons
Perforating arteries from the basilar artery
supply circumferential arteries to the lateral
pons
Pontine arteries
formed by the union of 2 internal cerebral veins
Vein of Galen
runs along the medial edge of temporal lobe in close association with the PCA
basal vein of Rosenthal
the superficial middle cerebral vein is connected to the transverse sinus via
