LECTURE HOMEWORK – Central Nervous System

1. Important centers for heart rate, blood pressure, respiration, swallowing, coughing, and vomiting are located in the
   1. Cerebrum.
   2. Medulla oblongata.
   3. Midbrain.
   4. Pons.
   5. Cerebellum.

    

2. Which is a function of the hypothalamus?
   1. Regulates autonomic nervous system functions
   2. Regulates the release of hormones from the posterior pituitary
   3. Regulates body temperature
   4. Regulates food intake (hunger) and water intake (thirst)
   5. All of the above.

3. The grooves on the surface of the cerebrum are called the
   1. Nuclei.
   2. Commissures.
   3. Sulci.
   4. Gyri.

4. Fibers that connect areas of the cerebral cortex within the same hemisphere are
   1. Projection fibers.
   2. Commissural fibers.
   3. Association fibers.
   4. All of the above.

5. The basal nuclei are located in the
   1. Inferior cerebrum
   2. Diencephalons
   3. Midbrain
   4. All of the above

6. The most superficial of the meninges is a thick, tough membrane called the
   1. Pia mater.
   2. Dura mater.
   3. Arachnoid mater.
   4. Epidural mater.

7. The cranial nerve involved in chewing food is the
   1. Trochlear (IV).
   2. Trigeminal (V).
   3. Abducens (VI).
   4. Facial (VII).
   5. Vestibulocochlear (VIII.)

8. The cranial nerve involved in feeling a toothache is the
   1. Trochlear (IV).
   2. Trigeminal (V).
   3. Abducens (VI)
   4. Facial (VII).
   5. Vestibulocochlear (VIII).

9. Water-soluble molecules such as glucose and amino acids move across the blood-brain barrier by
   1. Diffusion.
   2. Endocytosis.
   3. Exocytosis.
   4. Mediated transport.
   5. Filtration.

10. A collection of nerves that join together after leaving the spinal cord is called a
    1. Ganglion.
    2. Nucleus.
    3. Projection nerve.
    4. Plexus.

11. Cell bodies for sensory neurons are located in the
    1. Anterior horn of spinal cord gray matter.
    2. Lateral horn of spinal cord gray matter.
    3. Posterior horn of spinal cord gray matter.
    4. Dorsal root ganglia.
    5. Posterior columns.

12. The white matter of the spinal cord contains:
    1. Myelinated nerve fibers only.
    2. Unmyelinated nerve fibers only.
    3. Myelinated and unmyelinated nerve fibers.
    4. Soma that have both myelinated and myelinated nerve fibers.

13. The blood-brain barrier is effective against:
    1. Metabolic waste such as urea.
    2. Nutrients such as glucose.
    3. Alcohol.
    4. Anesthetics.

14. Which of the following would you not find in normal cerebrospinal fluid?
    1. Glucose
    2. Red blood cells
    3. Potassium
    4. Protein

15. Tremor at rest, shuffling gait, stooped posture, and expressionless face are characteristics of:
    1. Huntington’s disease.
    2. Parkinson’s disease.
    3. Spinal cord disease.
    4. Cerebellar disease.
