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
