1

What regions of the brain does the ACA supply?

Medial frontal lobe, medial parietal lobe

2

What deficits do you see if ACA is occluded?

Leg weakness, loss of sensation in legs, urinary incontinence, mood dysregulation

3

What regions of the brain does the MCA supply?

Lateral frontal, parietal, and superior temporal lobes, medial anterior temporal lobe

4

What deficits do you see if you MCA is occluded?

Hemiparesis of face/arm/trunk, hemisensory loss of face/arm/trunk, aphasia (left), hemineglect (right), homonymous hemianopsia

5

What regions of the brain do the medial striates supply?

ALIC, caudate

6

What deficits do you see if medial striates are occluded?

Frontal ataxia (Burns ataxia)-lesion in fronto pontine produes difficulty in intiating movements such as walking, although strength and coordination are normal

7

What regions of the brain do the lateral striates supply?

Genu of IC and PLIC, basal ganglia

8

What deficits do you see if lateral striates are occluded?

Hemiparesis of fae/arm/leg

9

What regions of the brain do the thalamogeniculates supply?

Thalamus

10

What deficits would you see if thalamogeniculates are occluded?

Thalamic pain: Acute-numbness, chronic-severe dyasthesia

11

What region of the brain does the anterior spinal artery supply?

Medial medulla

12

If anterior spinal artery is occluded in the brain, what tracts and cranial nerves would be affected? What findings would you see?

CST/pyramids, DC/medial lemniscus; CN XII --->

Contra hemiparesis, contra light touch, ipsi tongue weakness

13

What regions NOT IN THE BRAIN does the anterior spinal artery supply?

Medial/anterior 2/3rds of spinal cord

14

If anterior spinal artery is occluded NOT IN THE BRAIN, what cranial nerves and long tracts would be affected? What findings would you see?

No cranial nerves, CST, STT ->>>

quadriplegia, loss of pain/temp

15

What region of the brain does the vertebral artery supply?

Lateral medulla
