Answers
Answer:
A reflex is an involuntary motor response to a sensory stimulus. ... Reflexes perform many jobs for our central nervous system. They protect us from danger, they help us move our body, they help us see
Even though it is the brain that gives messages for muscles to act, in a reflex action, the spinal cord is the one that sends the messages to the muscles. Control and coordination in reflex actions are different. Our brain is a complex centre and the communication between the thinking part of the brain and other muscles is very intense. But, all this takes some time. This may not work well in sudden situations because even nanoseconds lost are crucial when communication happens between the brain and sense organs. Now, here is when the spinal cord comes into action.
When the body senses danger, the input-output of messages between the nerves and the corresponding action must be completed very quickly. The spinal cord sends the required signals to the muscles and the reflex action is completed. Since the action is instantaneous, the brain involvement is not much in reflex action
