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: -It is called a reflex action. Thus, Reflex action is an automatic, spontaneous and mechanical response to a stimulus controlled by spinal cord without the involvement of brain.
Detailed explanation-3: -Reflex action is a sudden and involuntary response to stimuli. It helps organisms to quickly adapt to an adverse circumstance that could have the potential to cause bodily harm or even death. Pulling our hands away immediately after touching a hot or cold object is a classic example of a reflex action.
