Question

what effect does exercise have on the nervous system?
a. prolonged exercise degenerates the nervous system.
b. increased blood flow reduces nerve sensitivity.
c. repetitive motion develops nerves and nerve endings.
d. higher body temperature impairs nerve message transmissions.
please select the best answer from the choices provided.
a
b
c
d

Explanation:

• Option A: Prolonged exercise does not degenerate the nervous system. Regular exercise is beneficial for overall health including the nervous system.
• Option B: Increased blood flow during exercise actually enhances nerve function rather than reducing nerve sensitivity.
• Option C: Repetitive motion in exercise can help develop nerves and nerve endings. For example, in activities like learning to play a musical instrument (which involves repetitive finger - hand motions) or in sports training, the nervous system adapts and nerves/nerve endings can develop to better coordinate movements.
• Option D: Moderate increase in body temperature during exercise is a normal physiological response and does not impair nerve message transmissions. In fact, within a normal range, it can even enhance some physiological processes related to nerve function.

Answer:

C. Repetitive motion develops nerves and nerve endings.
