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.

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 (a form of exercise) can stimulate the development and strengthening of nerves and nerve endings, which is a positive effect of exercise on the nervous system, so C is correct.
• Option D: Moderate increases in body temperature from exercise do not impair nerve message transmissions; rather, proper exercise can improve neural efficiency, so D is incorrect.

Answer:

C. Repetitive motion develops nerves and nerve endings.
