Detailed explanation-1: -A reflex is a rapid, unlearned, involuntary (automatic) response to a stimulus (change in the environment). Reflexes are responses that protect the body from potentially harmful events that require immediate action. They involve relatively few neurons (nerve cells) so that they can occur rapidly.
Detailed explanation-2: -What’s a Reflex? A reflex is an involuntary (say: in-VAHL-un-ter-ee), or automatic, action that your body does in response to something-without you even having to think about it. You don’t decide to kick your leg, it just kicks. There are many types of reflexes and every healthy person has them.
Detailed explanation-3: -This quick response is called a reflex, and reflexes occur without conscious thinking or planning, meaning the brain is not involved in them.
