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: -A reflex is an involuntary and nearly instantaneous movement in response to a stimulus. The reflex is an automatic response to a stimulus that does not receive or need conscious thought as it occurs through a reflex arc. Reflex arcs act on an impulse before that impulse reaches the brain.
Detailed explanation-3: -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.
Detailed explanation-4: -(a) Reflex action is a rapid and automatic response to a stimulus. It is not under the voluntary control of the brain. For example, if we unknowingly touch a hot plate, we immediately move our hand away from it. (b) The path travelled by an impulse during a reflex action is called a reflex arc.
