Answers (1)

best_answer

In a reflex action, the brain is not directly involved. Reflex actions are automatic and involuntary responses that occur without conscious awareness or thought. These actions are controlled by the spinal cord, which plays a key role in processing the stimulus and triggering a quick response. When sensory receptors detect a stimulus, they send the signal to the spinal cord. The spinal cord processes this information and sends a rapid response through motor neurons to the muscles, allowing the body to react immediately without requiring input or decision-making from the brain. This quick and automatic response is essential for protecting the body from potential harm. Hence, there is no role of the brain.
