Fill-In
1. Integration of the nervous and endocrine systems results from the link between the hypothalamus and the
_______________________________________ .
2. The fibers that permit communication between the two cerebral hemispheres are called ___________________ fibers.
3. Melatonin is secreted by the _________________________________________ .
4. The arbor vitae in the cerebellum is a branching array of ________________________________ .
5. Conscious thoughts , intellect, memory , and complex movement all originate in the ___________________________.
6. A disturbance of balance caused by a damaged cerebellum due to trauma or stroke results in a condition called
_________________________________________ .
7. Primary visual cortex is found in the ___________________________ lobe.
8. The control of Circadian rhythms is one of the functions of the __________________________________ .
Short Answer:
1.What brain regions make up the brain stem?
2. Which primary brain vesicle is destined to form the cerebellum, pons, and medulla oblongata?
3. The medulla oblongata is one of the smallest sections of the brain, yet damage there can cause death, whereas similar
damage in the cerebrum might go unnoticed. Why?
4. If the respiratory centers of the pons were damaged, what respiratory controls might be lost?
5. Identify the components of the cerebellar gray matter.
6. Using the mnemonic devise “Oh, Once One Takes The Anatomy Final, Very Good Vacations Are Heavenly,” list the
names of the 12 pairs of cranial nerves.
7. Briefly summarize the overall function of the cerebellum.
8. What varied roles does the hypothalamus play in the body?
9. Stimulation of what part of the brain would produce sensations of hunger and thirst?
10. Which structure in the brain would your Anatomy and Physiology instructor be referring to when talking about a
nucleus that resembles a sea horse and that appears to be important in the storage and retrieval of long-term memories In
which functional system of the brain is it located?
11. A police officer has just stopped Bill on suspicion of driving while intoxicated. The officer asks Bill to walk the
yellow line on the road and then to place the tip of his index finger on the tip of his nose. How would these activities
indicate Bill’s level of sobriety? Which part of the brain is being tested by these activities?
