Detailed explanation-1: -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-2: -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.
Detailed explanation-3: -Modern definitions of reflexes have captured the essence of Descartes’ description: an action or movement of the body that happens automatically, or without thinking, as a reaction to something. These definitions contain 3 core components: a stimulus, subconscious processing, and a resulting reaction.
