|
Anterior Cerebral Artery
|
Supplies most medial portions of frontal lobes and superior medial parietal lobes (lower extremity motor/sensory) - runs over corpus collosum
|
|
Anterior Communicating Artery
|
Connects the anterior cerebral arteries at their closest juncture
|
|
Internal Carotid Artery
|
Ascends through base of skull to give rise to the anterior and middle cerebral arteries, and connect with posterior half of circle of Willis via posterior communicating artery
|
|
Middle Cerebral Artery
|
Trifurcates into temporal, frontal, and parietal branches that supply most of the parenchyma of these lobes (lateral surface of the brain) - runs in Sylvian fissure after branching off carotid T junction
|
|
Posterior Communicating Artery
|
Connects the anterior circle of Willis with the posterior cerebral artery of vertebral-basilar circulation posteriorly
|
|
Posterior Cerebral Artery
|
Supplies the occipital lobe and the inferior portion of temporal lobe. A branch supplies the choroid plexus.
|
|
Superior Cerebellar Artery
|
Supplies the dorsal cerebellum, pons, and midbrain
|
|
Basilar Artery
|
Formed by the junction of the two vertebral arteries, it terminates as a bifurcation into the posterior cerebral arteries; supplies media medulla and pons
|
|
Anterior Inferior Cerebellar Artery
|
Supplies the inferior cerebellum, lateral pons, and part of the medulla
|
|
Vertebral Artery
|
Emerge from the posterior base of skull and merge to form the basilar artery
|
|
Posterior Inferior Cerebellar Artery
|
Supplies the inferior-posterior cerebellum, cerebellar peduncles, choroid plexus in 4th ventricle, and lateral medulla
|
|
Anterior Spinal Artery
|
Descends along the anterior (ventral) aspect of the spinal cord; branches off of vertebrals
|
|
Lenticulostriate arteries
|
small penetrating arteries off the MCA that supply putamen, globus pallidus, and part of the internal capsule
|
|
thalamoperforators
|
small arteries that branch off tip of basilar and beginning of PCA, enter brain via interpeduncular fossa and supply thalamus/subthalamus
|
|
septal vein
|
runs in anterior septum pellucidum, primary drainage from forebrain, stop of foramen of Monro to join with thalamostriate vein to become internal cerebral veins
|
|
internal cerebral veins
|
pair of veins formed from septa veins and thalamostriate veins, as well as drainage from choroid plexus; run along roof of third ventricle
|
|
great vein of Galen
|
forms under corpus collosum splenium as one central vein, main drainage for all the veins that serve the internal aspects of the cerebrum
|
|
inferior sagittal sinus
|
runs at bottom of falx cerebri, joins with great vein of Galen to become straight sinus
|
|
ACA syndrome
|
contralateral leg weakness and sensory loss
|
|
MCA syndrome
|
contralateral face and arm > leg weakness and sensory loss, field cut, aphasia, neglect
|
|
PCA syndrome
|
contralateral field cut
|
|
lacunar syndrome
|
contralateral motor or sensory deficit without cortical signs
|
|
basilar artery syndrome
|
oculomotor deficits and/or ataxia with crossed sensory/motor deficits
|
|
verterbral artery syndrome
|
lower cranial nerve deficits and/or ataxia with crossed sensory/motor deficits
|
