Flashcards in Exam 1 Brain Arterial Supply Deck (24):
0

Carry blood INTO cranial vault

Internal Carotid Artery

1

Pass behind the ear into the temporal lobe & enter the subarachnoid space

Internal carotid artery

2

Runs posteriorly to the medial end of the fissure of Sylvus

Internal carotid artery

3

Bifurcates into 2 main branches: anterior & middle cerebral artery

Internal carotid artery

4

Goes above the optic chiasm to the medial surface of the cerebral hemispheres.

Anterior Cerebral artery

5

Aches around the genu (horn) of the corpus callosum

Anterior cerebral artery

6

Supplies blood to the medial cortex

Anterior cerebral artery

7

Travels along the longitudinal fissure

Anterior cerebral artery

8

Most commonly involved in strokes

middle cerebral artery

9

Brings blood to the entire lateral aspect of each hemisphere

Middle cerebral artery

10

provides most of the blood supply to the corpus striatum

Middle cerebral artery

11

Internal carotid artery also includes the _______ ______ artery & ______ ________ artery

Anterior communicating artery & posterior communicating artery

12

Joins the anterior cerebral arteries of each hemisphere together

Anterior Communicating artery

13

Joins the middle cerebral arteries to the posterior cerebral arteries, which are part of the basilar artery system

Posterior communicating artery

14

Both ascend the spinal column & enter the brain through the magnum foramen.

Vertebral artery

15

Once inside the brain, they continue to ascend traveling beside the brain stem. At the lower border of the pons the two______ ______ join together to form the basilar artery

Vertebral artery

16

Supplies the cerebellum & takes blood to the lateral medulla

Posterior inferior cerebellar

17

The sides of the Pons & the cerebellum receive blood from the ______ ______ _____ artery & the ________ ______ artery. Both branch off of the basilar artery

Anterior inferior cerebellar & Superior cerebellar artery

18

Anterior inferior cerebellar artery also has a branch, artery that supplies the inner ear

Labyrinthine/ internal auditoritory

19

At the superior border of the pons, the basilar artery divides to form the 2 ________ _______ arteries

Posterior cerebral arteries

20

Before the basilar artery divides, several other arteries arise from it. Name these:

Anterior, Inferior, and posterior cerebellar arteries as well as the pontine
branches.

21

The cerebellum & the pons are supplied by branches of the:

Basilar artery

22

Posterior cerebral arteries supply the medial area of the ______ ____ & the inferior aspects of the _____ ___

Occipital lobes; Temporal lobes

23

Also supply the midbrain & deliver blood to the thalamus

Posterior cerebral arteries
