Sensory receptors provide information to the central nervous system (CNS) about the status of the environment. Each sensory receptor responds to a particular kind of stimulus energy (chemical, electromagnetic, mechanical, or thermal). Sensory receptors are transducers that are specialized to transform the stimulus energy into an electrochemical potential. Information about the stimulus is encoded by the discharge of action potentials in the sensory nerve. These sensory discharges are then conducted to the sensory areas of the nervous system where they are decoded and analyzed.
