The sudden involuntary movement in a voluntary organ; in response to a stimulus; is called reflex action. Examples of reflex action: (a) Moving your hand away from a hot iron plate. (b) Blinking of eyes. Reflex Arc: The path of electrical impulse during a reflex action is called reflex arc.
It is a simple form of behaviour in which the same stimulus produces the same response every time, e.g. if we unknowingly touch a hot plate, we immediately move our hand away from it. moving our foot away on stepping something sharp.
