Question

what is the role of spinal cord an
d brain on reflex
​

Answer 1

Answer:

Carrying signals from the brain: The spinal cord receives signals from the brain that control movement and autonomic functions. Carrying information to the brain: The spinal cord nerves also transmit messages to the brain from the body, such as sensations of touch, pressure, and pain.

Answer 2

Explanation:

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
