No.. nervous control is both somatic or autonomic mns involuntary or voluntary ... so assertion is true and reason is wrong.

Quick and Short Duration of Nervous Control/Response
Nervous control or response is indeed very quick but for a short duration. This is because the nervous system is responsible for rapid communication within the body, allowing for immediate responses to stimuli. When a stimulus is detected by sensory receptors, such as touch or pain, the nervous system quickly processes this information and generates a response.

Reason: Involuntary Nature of Nervous Control
The reason behind the quick but short duration of nervous control lies in the involuntary nature of the nervous system. Involuntary responses are those that occur automatically, without conscious thought. These responses are essential for maintaining homeostasis and ensuring the body's survival.
When a stimulus is detected, the nervous system sends signals through neurons to the brain or spinal cord, where the information is processed. The brain then sends signals back through motor neurons to initiate a response, such as moving away from a painful stimulus or adjusting body temperature.
Involuntary responses are quick because they do not require conscious thought or decision-making. They are automatic, allowing the body to react swiftly to potential threats or changes in the environment. However, these responses are typically short-lived because they are designed to address immediate needs and then return the body to a state of balance.
In conclusion, the quick and short duration of nervous control/response is a result of the involuntary nature of the nervous system. This system allows for rapid communication and immediate responses to stimuli, ensuring the body's survival and well-being.
