Which Blood Vessel Enters the Brain Through the Carotid Canal

Question

Which blood vessel enters the brain through the carotid canal?
A) internal carotid artery
B) external carotid artery
C) common carotid artery
D) internal jugular vein
E) carotid sinus

Accepted Answer

The internal carotid artery is responsible for supplying blood to the brain and enters the skull through the carotid canal. The external carotid artery supplies blood to the face and scalp, while the common carotid artery is the main artery that branches off into the internal and external carotid arteries. The internal jugular vein drains blood from the brain and face, while the carotid sinus is a dilation in the wall of the internal carotid artery that senses changes in blood pressure.
