Week 4: Vascular Brain Anatomy Flashcards
Which 2 major vessels provide the arterial supply to the brain?
•Internal carotid arteries
•Vertebral arteries
Which of these vessels provide anterior circulation and arise anteriorly in the neck?
Internal carotid arteries
Which provides posterior circulation and arises posteriorly in the neck?
Vertebral arteries
At what bony landmark can you find the bifurcation of the common carotid artery?
C3-C4
What is the carotid siphon and where is it?
The S shaped curve of the internal carotid artery (ICA) located within the cavernous sinus of the skull
Which artery is the largest cerebral artery?
Middle Cerebral Artery
Which arteries connect the anterior and posterior circulations of the brain?
Posterior communicating arteries
Which arteries arise from the subclavian arteries and ascend the neck through the transverse foramina of the C-Spine?
Vertebral arteries
Which arteries unite to form the basilar artery?
Vertebral arteries
Circle of Willis
Dural sinuses
What are the dural venous sinuses?
A network of channels in the brain that drain blood from the brain and return it to the heart
What major veins in the neck drain venous blood from the head?
External, Internal, and Anterior jugular veins
