BIOD 101: EXAM TEST WITH SOLUTIONS
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.
Correct 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.
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:
Correct 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 3
pts
Describe the function of the brain ventricles. Your
Answer:
Brain ventricles ARE 4 and are found inside the brain and filled with CSF. 2
laterals and 3rd and 4th ventricles all of them drain in the central canal of
the spinal cord and contains CSF; their main function it is where the CSF is
made which helps to absorb impacts when the brain faces them for any
activity or movements
There are four ventricles in the interior of the brain, chambers filled with
cerebrospinal fluid which is produced there. Once formed the CSF circulates
through the ventricles and into the subarachnoid space bathing and floating the
brain.
