A reflex occurs when a nerve impulse passes over a
reflex arc, in response to a stimulus, a
change in the environment that
affects receptors in the organism. Reflexes are either
voluntary or involuntary according to where and why
they occur. An example of an involuntary response is
the knee jerk reflex, which occurs in response to
tapping of the tendon in the knee,
causing the tendon and muscles to stretch.
