Answer 2

Answer:

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 defect 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 it to quickly ( output) is known as a reflex arc. Reflex arc 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...
