AP II: MODULE 2 EXAM Q & A
Question 1
pts
This layer of the meninges is tightly attached to the brain.
Your
Answer:
Pia Mater
Pia mater (menix)
Which of the following is false concerning the sympathetic
nervous system? It is also called the thoracolumbar division.
It is also called the craniosacral division.
, AP II: MODULE 2 EXAM Q & A
The primary neurotransmitter is norepinephrine.
It inhibits the digestive tract.
If you were hiking in the woods and came across a mountain lion, which
division of your nervous system would have increased activity? Explain
your answer.
Your Answer:
The sympathetic nervous system would have increased activity as it is
responsible for preparing our bodies to respond to stressful situations.
If someone sustains an injury to the area of the spinal cord, as shown
below by the blue oval, would you be more likely to see paralysis or
decreased sensation? Explain your answer.
, AP II: MODULE 2 EXAM Q & A
Your Answer:
You would be more likely to see decreased sensation because sensory neurons
enter the spinal cord posteriorly.
One of your patients sustained a hemorrhagic CVA. You notice they
have rigid
movements when moving their arms. They also have difficulty forming a plan
to move their body. What area of the brain is most likely impacted? Explain
your reasoning.
Your Answer:
The basal ganglia is responsible for executing a motor plan and to slow and
control fine movements (creating the rigid movements).
Apraxia, or impaired motor planning. Apraxia results in rigid movements and
difficulty executing a motor plan.
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.
, AP II: MODULE 2 EXAM Q & A
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.

Regulates sleep
Links the nervous and endocrine systems
