ANATOMY

Detailed explanation-1: -The brain receives blood from two sources: the internal carotid arteries, which arise at the point in the neck where the common carotid arteries bifurcate, and the vertebral arteries (Figure 1.20). The internal carotid arteries branch to form two major cerebral arteries, the anterior and middle cerebral arteries.

Detailed explanation-2: -The carotid arteries are a pair of blood vessels located on the sides of your neck that deliver blood to your brain and head. Carotid artery disease occurs when fatty deposits (plaques) clog the blood vessels that deliver blood to your brain and head (carotid arteries).

Detailed explanation-3: -There are two carotid arteries, one on the right and one on the left. In the neck, each carotid artery branches into two divisions: The internal carotid artery supplies blood to the brain. The external carotid artery supplies blood to the face and neck.

Detailed explanation-4: -The internal carotid artery, being one of the most clinically relevant and vital arteries, supplies oxygenated blood to crucial structures such as the brain and eyes.

Detailed explanation-5: -The carotid arteries are vital for providing oxygenated blood to the brain. Just like all arteries, they are susceptible to atherosclerosis, which can lead to stenosis and distal embolism of plaque.
