For Example : Blinking of eyes, movement of diaphragm, withdrawal of hand or foot every time when a needle or hot object is touched, sneezing, hunger etc. (1) Sensory (receptors) (a) It occur in sense organs. (b) It receive stimuli by dendrites. (c) It transmit impulse towards brain and spinal cord through axons. (2) Motor (Effectors) (a ... Discover what reflex actions & how reflexes keep us safe and their importance in our everyday life Reflex action is a type of behavior that is not consciously controlled by the brain, but rather, it is mediated by the spinal cord and peripheral nerves. Reflex action is an essential survival mechanism that allows an organism to respond quickly to potentially harmful stimuli. A reflex arc is a pathway that a nerve impulse follows during a reflex action. Reflex arcs are highly beneficial in situations that require a quick response and do not involve conscious thought. A typical example of a reflex action is the patellar reflex (‘knee jerk’ response), which occurs when the patellar tendon is tapped.
