3. What is the purpose of the blood-brain barrier? Describe its maintenance from a cellular
level.
**Answer:** The blood-brain barrier is a diffusion barrier that prevents most particles from
entering the central nervous system tissue, maintaining a stable chemical environment for
the nervous system. It is formed by the relatively impermeable brain capillaries, due to the
presence of astrocytes (glial cells) that support and maintain the integrity of the barrier.
4. All the following are functions of the hypothalamus except:
**Answer:** D. Relays sensory impulses to the cerebrum
5. What is the largest portion of the brain?
**Answer:** B. Cerebrum
6. This region of the brain acts to coordinate multiple sources of sensory information.
**Answer:** C. Association area
7. A patient is having difficulty understanding language but is still able to speak fluently. The
