Anatomy and Physiology II 102: Module 2 test

Question 1
This layer of the meninges is tightly attached to the brain.
Pia mater (menix)


Question 2
The _______ fissure separates the right and left cerebral hemispheres.
Median longitudinal


Question 3
What is the purpose of the blood-brain barrier? Describe its maintenance from a cellular level.
The blood-brain barrier is a diffusion barrier which prevents most particles from entering the
central nervous system tissue, keeping the brain and spinal cord separate from general blood
circulation. The blood-brain barrier is formed by the relatively impermeable brain capillaries,
due to the glial cells astrocytes. Maintenance of the blood-brain-barrier is important to
provide a stable chemical environment for the nervous system.


Question 4
All the following are functions of the hypothalamus except:


Maintain homeostasis
Controls the pituitary gland
Links the nervous and endocrine systems
Relays sensory impulses to the cerebrum
