Such a connection of detecting the signal from the nerves and responding to it quickly is known as reflex arc. Reflexarcs are formed in the spinal cord and the information reaches the brain andbrain responses to it.

Answer 2

HEY FRIEND HERE IS UR ANSWER,

Reflex actions are formed instantaneously in response to the stimulus that has no time to think. For instance 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 reflex arc.

Reflex action are generated in spinal cord and the information also reaches brain. This helps the brain to record this event and remember it for future use.  Brain helps the person the person to get awareness of the stimulus and prevent himself from that situation again.
