BIOD 152 Module 2 Exam
Question 1 pts
This is the most superficial layer of the brain meninges.
Your Answer:
Dura Mater (menix)
Dura 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:
a barrier that prevents most particles from entering the CNS tissue
keeping the brain and spinal cord from general blood circulation.
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.
