Question

what are brain's role in reflexive actions?

Answer 1

Reflex arcs i.e the pathways of reflex actions are in the spinal cord.

The brain had no role during a reflex action but it helps us to remember our immediate response to the stimulus.

For Eg. If u touch a hot plate u will suddenly withdraw ur hand. This is reflex action. And the next time u never touch a hot plate. This (remembrance) is done by brain.

Hope this helps you

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.
