Question: 59
14. A disease results in the death of Schwann cells. Which portion of the nervous system is NOT likely to be affected?
- A. Central nervous system
- B. Somatic nervous system
- C. Autonomic nervous system
- D. Parasympathetic nervous system
Correct Answer: A
Explanation:
Schwann cells are responsible for myelination of cells in the peripheral nervous system. Thus, the central nervous system is unlikely to be affected. The peripheral nervous system includes the somatic nervous system and the autonomic nervous system. The autonomic nervous system is composed of both the parasympathetic and sympathetic nervous systems. Thus, choice (A) is the right answer.
