2. Name the four elements in a reflex arc and give an example of two
neuron reflex arc as well as a three neuron reflex arc.
3. List of the four major region of the brain and give their functions.
4. Explain the functions of the cerebral cortex. Specifically mention
the locations of the auditory area, olfactory area, visual area, primary
motor area, Broca’s area, speech area, language comprehension
5. Describe the functions of the brainstem and explain why injury
to the brainstem often results in a coma.
6. Give the functions of the cerebellum.
7. List the 12 cranial nerves and give their function as well as a
test for functionality.
8. Describe how stroke symptoms such as left side paralysis indicate
the region of the brain where the blood clot occurred.
