Branches off aorta

Brachiocephalic
Common carotid
Left subclavian

1

Brachiocephalic

Turns into right subclavian

2

Subclavian veins

Turn into the vertebral arteries

3

Vertebral arteries

Come together at medulla pons junction to form the basilar artery
Post inferior cerebellum artery (PICA) branches off of vertebral arteries

4

Basilar artery

Runs from medulla pons junction up to midbrain
-ant inf cerebeller artery (AICA)
-superior cerebellar artery
-post cerebral artery

5

Posterior circulatory system

Subclavian, vertebral, basilar, AICA, PICA, SCA, PCA

6

Internal carotid

Comes off of common carotid and brachiocephalic
Goes up to free the anterior circulatory system
Branches:
-MCA
-ACA

7

Anterior communicating artery

Connects bilateral ACAs

8

Posterior communicating artery

Connects bilateral internal carotid and PCA

9

Circle of Willis

Formed by ACA, MCA, PCA, internal carotid, ant and post communicating arteries

10

Internal carotid (ICA) supplies

The inside part of the brain and a little of the top

11

ACA supplies

Top of brain and the leg part of te homunculus

12

MCA supplies

Outer surface of brain an basal ganglia
Head and trunk of homunculus

13

PCA

Supplies post brain and cerebellum
Expect vision and coordination deficits
