What does the common carotid branch into?
It branches into the internal and external carotid arteries.
At what level does common carotid branch into the internal and external cartotid arteries?
Branches into the internal and external cartotid arteries at the level of C4
What forms the first part of the internal carotid artery?
The carotid sinus
Where does the internal carotid artery enter the skull?
Enters the skull through the carotid canal of the temporal bone
What does the internal carotid artery branch into, and where?
Internal carotid artery branches into the anterior and middle cerebral arteries at the pituitary gland.
Where does the anterior cerebral artery supply blood to?
Supplies blood to the frontal lobe of the cerebrum
Where does the middle cerebral artery supply blood to?
Supplies blood to the temporal and parietal lobes
What artery does th vertebral artery arise from?
Vertebral artery arises from the subclavian arteries
Where do the verebral arteries enter the skull?
Enter the skull through the foramen magnum
Where do the verebral arteries ascend through?
Ascends through the transverse formania of the C-spine
What do the right and left verbral arteries unite to form?
They unite to form the basilar artery
Where does the basilar artery travel in relationi to the brain stem?
Travels anterior to the brain stem
What does the basilar artery split to form?
Splits to form the right and left posterior cerebral arteries
If contrast was injected into the posterior cerebral arteries, which side(s) of the brain would contrast be present in?
Contrast would be present into the posterior portion of both left and right sides of the cerebrum and cerebellum

What is this describing?
Elaborate anastomoses of the entrire circulation to the brain
The circle of willis
If inserting a catheter into the brain, is it better to go into the left or the right side of the brain?
Left side, because its eaiser to acess due to the fact that the brachiocephalic trunk is not present
What does the circle of willis surround?
Surrounds the pituitary gland
What connects the anterior cerebral arteries?
The anterior communicating artery
What is the main purpose of the anterior communicating artery?
To provide a right to left shunt in the brain for prevention of blockages
What is the main purpose of the posterior communicating artery?
Provides an antterior to posterior shunt in the brain for prevention of blockages
What does the posterior communicating artery connect?
Connects the posterior cerebral artery with the internal carotid artery
