Detailed explanation-1: -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. In fact, we’re born with most of them.
Detailed explanation-2: -Reflex responses are rapid, stereotyped involuntary movements elicited by a stimulus that requires a quick reaction at an involuntary level-for example, withdrawal of a bare foot that has touched a sharp or hot object.
Detailed explanation-3: -Autonomic reflexes are unconscious motor reflexes relayed from the organs and glands to the CNS through visceral afferent signaling.
Detailed explanation-4: -Reflex actions These different types of neurons work together in a reflex action . A reflex action is an automatic (involuntary) and rapid response to a stimulus, which minimises any damage to the body from potentially harmful conditions, such as touching something hot.
