An inborn and rapid response to a stimulus from the external environment. An automatic response that occurs very rapidly & without conscious  control. any action performed involuntarily in consequence of an impulse or impression transmitted along afferent nerves to a nerve center, from which it is reflected to an efferent nerve, and so calls into action certain muscles, organs, or cells

reflex action, also known as a reflex, is an involuntary and nearly instantaneous movement in response to a stimulus.

For a reflex, reaction time or latency is the time from the onset of a stimulus until the organism responds.

In animals, reaction time to visual stimuli is typically 150 to 300 milliseconds.
