This layer of the meninges is tightly attached to the brain.
Pia mater (menix)
The _______ fissure separates the right and left cerebral hemispheres.
Median longitudinal
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.
