Front 5

ACA

Back 5

travel in interhemispheric fissures

2 main branches: pericallosal and callosomarginal

supply anterior medial surface: frontal to anterior parietal

Hint 5

Front 6

MCA

Back 6

turns laterally and enters the Sylvian fissure

usually bifurcates to superior and inferior divisions but variable

Front 7

MCA superior division

Back 7

supply lateral frontal lobe, usually including the peri-Rolandic cortex

Front 8

MCA inferior division

Back 8

supply lateral temporal lobe and variable portion of the parietal lobe

Front 9

PCA

Back 9

supply the inferior-medial temporal lobe and medial occipital lobe

wrap aroid the midbrain, supplying it

Front 10

lenticulostriate arteries

Back 10

arise from initial portion of the MCA before it enters the Sylvian fissure

supply large regions of the basal ganglia and internal capsule

Front 11

anterior choroidal artery

Back 11

arise from the ICA

supply portions of the globus palidus, putamen, thalamus and posterior limb of the internal capsule

Front 12

recurrent artery of Heubner

Back 12

arise from initial portion of the ACA

supply portions of the head of the caudate, anterior putamen, globus palidus, and internal capsule

Front 13

thalamoperforator arteries

Back 13

arise from proximal PCA

supply the thalamus and sometimes extend to the posterior limb of the internal capsule

Hint 13

Front 14

Superficial cerebral vessels

Back 14

ACA, MCA, PCA

Front 15

Deep cerebral vessels

Back 15

lenticulostrate, anterior choroidal, recurrent artery of Heubner, and thalamoperforators

Front 16

Cortical border zone infarctions

Back 16

Infarctions of the cortex and adjacent subcortical white matter located at the border zone of ACA/MCA and MCA/PCA

Hint 16

Front 17

Internal border zone infarctions

Back 17

Infarctions of the deep white matter of the centrum semiovale and corona radiata at the border zone between lenticulostriate perforators and the deep penetrating cortical branches of the MCA or at the border zone of deep white matter branches of the MCA and the ACA.

Hint 17

Front 18

Medial lenticulostriate arteries

Back 18

Branches of the A1-segment of the anterior cerebral artery.
They supply the anterior inferior parts of the basal nuclei and the anterior limb of the internal capsule.

Hint 18

Front 19

Lateral lenticulostriate arteries

Back 19

Branches of the horizontal M1-segment of the middle cerebral artery.
They supply the superior part of the head and the body of the caudate nucleus, most of the globus pallidus and putamen and the posterior limb of the internal capsule.

Fetal Origin of the Posterior Cerebral Artery

Back 20

Fetal origin of the posterior cerebral artery occurs when the embryonic posterior cerebral artery fails to regress. It may occur on the right side (10% of the general population), the left side (10% of the general population), or bilaterally (8% of the general population)

Hint 20

Front 21

Fenestration of the anterior cerebral artery

Back 21

The prevalence of fenestration of the A1 segment is between 0% and 4% in anatomic imaging studies (10) and 0.058% in angiographic studies

Hint 21

Front 22

Middle cerebral artery duplication

Back 22

Middle cerebral artery duplication occurs when a middle cerebral artery branch arises above the bifurcation of the internal carotid artery. The duplicate vessel parallels the main middle cerebral artery and supplies the anterior temporal lobe (13) (Fig 5). The reported prevalence of middle cerebral artery duplication is 0.2%–2.9% (14).

Hint 22

Front 23

Basilar artery fenestration

Back 23

Basilar artery fenestration has been found in 0.6% of angiographic examinations (19) and approximately 5% of autopsies (20). Basilar artery fenestrations are most commonly located in the proximal basilar trunk, close to the vertebrobasilar junction (3)
