1. This Layer of the meninges is tightly attached to the brain - (ANSWERS)Pia Mater (Menix)
!@#$$$$$$$$$$%
2. The ______ fissure separates the cerebrum from the cerebellum. -
(ANSWERS)Transverse
3. What is the purpose of the blood-brain barrier? Describe its maintenance from a cellular
level. - (ANSWERS)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.

8. What is muscle tone and how is it maintained? - (ANSWERS)Muscle tone is the degree
at which muscles remain partially contracted while at rest. Muscle tone is continuously
monitored and maintained by the cerebellum to keep bones and joints in place.
9. Which statement is false concerning the brainstem?
A. The midbrain portion of the brainstem is continuous with the spinal cord.
B. The pons helps to regulate breathing.
C. The midbrain contains the superior and inferior colliculi.
D. The medulla contains reflex centers to regulate vasoconstriction - (ANSWERS)A.
The midbrain portion of the brainstem is continuous with the spinal cord
10. Which of the following is true concerning the cerebellum?
A. The gray matter is internal while the white mater is external.
B. The cerebellum works to plan body movements by relaying information spinal
cord.
C. The anterior lobe receives information from the body trunk.
D. The vermis coordinates the trunk and shoulder movements. - (ANSWERS)C. The
anterior lobe receives information from the body trunk
11. Alzheimer's disease impacts which region(s) of the brain?
A. Occipital lobe
B. Frontal lobe
C. Parietal lobe
D. Hippocampus
E. All the above - (ANSWERS)E. All of the above
12. Which of the following is false concerning a CVA?
A. An ischemic stroke is also known as a "brain bleed".
B. A TIA is a form of an ischemic stroke.
C. Stroke survivors may regain some lost functions through therapy.
D. A hemorrhagic stroke is due to a broken blood vessel. - (ANSWERS)A. An
ischemic stroke is also known as a "brain bleed"
13. A patient is unable to extend his fourth and fifth digits when asked to open his hand.
What is most likely the cause?
