Flashcards in Blood Supply to the Brain (FINAL) Deck (15):
1

Anterior Communicating Arteries

  •  A blood vessel of the brain that connects the left and right anterior cerebral arteries across the commencement of the longitudinal fissure

2

Basilar Artery

  • Supplies blood to the posterior part of circle of Willis
  • Supplies blood to the brain stem (life support) 

3

Posterior Communicating Arteries

 

4

Anterior Cerebral Arteries

  • A pair of arteries on the brain that supplies oxygenated blood to most midline portions of the frontal lobes and superior medial parietallobes.
  • The two anterior cerebral arteries arise from the internal carotid artery and are part of the circle of Willis

5

Vertebral Arteries

6

Internal Carotid Arteries

  • The internal carotid artery supplies the brain

7

Name of this structure

Circle of Willis 

8

What is the purpose of the circle of Willis?

Supplies blood to the brain and surrounding structure

9

What does the Circle of Willis comprise of? 

  • Anterior cerebral artery (left and right)
  • Anterior communicating artery
  • Internal carotid artery (left and right)
  • Posterior cerebral artery (left and right)
  • Posterior communicating artery (left and right)
  • Basilar artery
