Question

An important artery that supplies blood to the brain is the ________ artery.
A) internal carotid
B) external carotid
C) mental
D) azygos
E) maxillary

Accepted Answer

The internal carotid artery is a major blood vessel that supplies oxygenated blood to the brain. It branches off from the common carotid artery, located in the neck, and travels up through the carotid canal in the temporal bone of the skull to reach the brain. The internal carotid artery is responsible for supplying blood to the anterior (front) portion of the brain, including the cerebrum and other vital structures. The external carotid artery supplies blood to the face, scalp, and neck, but not to the brain. The mental artery supplies blood to the chin and lower lip, the azygos artery is not located in the head or neck, and the maxillary artery supplies blood to the face and oral structures, but not directly to the brain.
