Blood flow to active regions of the brain is controlled by:
A)the myelin sheath
B)the reflex arc
C)glial cells
D)interneurons

Question

Quizplus · Accepted Answer

Glial cells play an important role in regulating the blood flow to active regions of the brain. They release chemicals that signal the blood vessels to dilate and increase blood flow, which brings in more oxygen and glucose for the neurons to use. This process is known as neurovascular coupling. The myelin sheath, reflex arc, and interneurons are not directly involved in controlling blood flow to the brain.
