Web1 Human Physiology Lab (Biol 236L) Sensory Physiology External sensory information is processed by several types of sensory receptors in the body. These receptors respond to external stimuli, and that information is changed into an electrical signal (action potential) that is transmitted along the sensory division (afferent pathway) of the peripheral nervous … WebThe skin is the body's largest organ. It covers the entire body. It serves as a protective shield against heat, light, injury, and infection. The skin also: Regulates body temperature Stores water and fat Is a sensory organ Prevents water loss Prevents entry of bacteria Acts as a barrier between the organism and its environment
