Detailed explanation-1: -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-2: -Its reaction is automatic and does not involve thinking about it. It is called a reflex action. Thus an automatic, spontaneous and mechanical response to a stimulus controlled by the spinal cord without the involvement of the brain is called a reflex action.
Detailed explanation-3: -A reflex is an automatic reaction to a stimulus. A stimulus is something that causes an action. In a simple reflex, a neuron brings information about a stimulus to the brain or spinal cord and connects with a motor neuron. The motor neuron sends out a message to a muscle.
