Question 1
pts
This layer of the meninges is tightly attached to the brain.
Your Answer:
Pia Mater
Pia mater (menix)
Question 2
pts
The _______ fissure separates the right and left cerebral hemispheres.
Your Answer:
Median Longitudinal
Median longitudinal
Question 3
pts
What is the purpose of the blood-brain barrier? Describe its maintenance from a cellular
level.
Your Answer:
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 8
pts
Describe how memories are stored and retrieved in the brain. Include a specific brain
region.
Your Answer:
Memories are not stored in one specific area within the brain but instead are
stored throughout the cerebral hemispheres. The hippocampus acts as a memory
