Detailed explanation-1: -A spontaneous, automatic, involuntary, response to a stimulus that occurs without any conscious effort or thought and requires the involvement of the CNS, is known as the reflex action.
Detailed explanation-2: -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-3: -Reflexes are unconscious responses, which means they are automatic and do not require the brain to create the action.
Detailed explanation-4: -Reactions are voluntary responses whereas reflexes are involuntary or unintentional (and not subject to conscious control in most cases). Each type of response is initiated by a sensory stimulus that may be visual, audible, tactile, olfactory, or gustatory in nature.
