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.

The answer is C: Repetitive motion develops nerves and nerve endings.

Physical training and exercise involves repetitive motions and have the ability to affect nervous system favorably. This is due to the fact that the central nervous system (nerves and brain) is involved as the coordination center for all behaviors in the body. It receives information both from internal and external environment of the body.
During exercise, several things do happen like rise in demand for energy which results to generation of heat thus raising body temperatures. This and other information have to be relayed within the body through the nervous system which results to sensory feedbacks accompanied by alterations in motor activity and psychological functioning. This results to motor cortex and spinal cord structure alterations in response to training and exercise and may lead to motor recovery and restoration to those who are paralyzed. Thus training and exercise develops nerves and nerve

While performing the exercise, repetitive motion develops nerves and nerve ending. Thus, the correct option is (C).

Further Explanation:

Exercise mainly affects the musculoskeletal systems, cardiovascular, and pulmonary. It affects the metabolic rate of the body. It also affects the nervous system of an individual but not very readily. The CNS is very complex and difficult to analyze. While performing any physical activity periphery, give sensory feedback, which affects the physiological function and also the motor activity of the CNS.

Physical exercise and activities mainly involve cyclic motions and consist of the capability to affect the nervous system adversely. Nerves, spinal cord, and brain are part of CNS and involve the coordination center for all activities in the body. While performing the exercise body of the individual requires energy and generates heat in the body. Sometimes vigorous exercise causes central fatigue. Exercise also provides benefit to the CNS, help in coping from stress and anxiety.
