Answer 1

Explanation:

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.

Normal function of the brain's control centers is dependent upon adequate supply of oxygen and nutrients through a dense network of blood vessels.
