what is the role of brain in reflex action
Answers
Explanation:
Answer: The purpose of reflex action is to provide quick response in situations where the organism does not have enough time to think. Reflex arcs are formed in the spinal cord, although the information inputs also reach the brain. This helps the brain to record this event and remember it for future use.

Reflex actions are sudden responses. It is an involuntary action which does not involve thinking. For example, when we touch a hot object, we withdraw our hand immediately without thinking.
The sensory nerves that detect the heat are connected to the nerves that move the muscles of the hand. Such a connection of detecting the signal from the nerves (input) and responding to it quickly (output) is known as a reflex arc. Reflex arcs are formed in the spinal cord but the information is still sent to the brain. The brain doesn’t have a significant response to it.
