A body can respond to danger unconsciously in something known as a reflex. A reflex follows these basic steps: Receptor detects stimulus and creates an action potential in the sensory neurone. Sensory neurone carries impulse to spinal cord. Relay neurone connects sensory neurone to motor neurone in the brain or spinal cord.

WebThe reflex arc is made up of an afferent pathway from a receptor and an efferent pathway to an effector: it is similar in outline to a negative feedback control system (Fig. 13.3).Indeed the whole range of regulatory reflexes are themselves negative feedback control systems.
