Answers
Explanation:
Reflex Action : It is an involuntary and nearly instantaneous response to stimulus . For example : Hand is withdrawn when, it accidentally touches a hot object.
The pathway taken by a stimulus to travel from receptors organ to effector organ is known as reflex arc.
Involuntary action is the set of muscle movement which do not require thinking. But it is controlled by brain for example beating of heart beat. While on the other hand, the reflex action is rapid and spontaneous action in response to any stimulus which doesn't involve brain.
