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 generally does not degenerate the nervous system; in fact, regular exercise can be beneficial, so A is incorrect.
• Option B: Increased blood flow from exercise typically enhances nerve function and sensitivity, not reduce it, so B is incorrect.
• Option C: Repetitive motion (exercise - related) can stimulate the development of nerves and nerve endings as the body adapts to the movement, improving neural connections, so this is a valid positive effect of exercise on the nervous system.
• Option D: Moderate increase in body temperature during exercise does not impair nerve message transmissions; in fact, proper physiological responses during exercise support neural function, so D is incorrect.

Answer:

C. Repetitive motion develops nerves and nerve endings.
