# Neurons Neurons are individual nerve cells that receive, process, and relay information. There are three types of neurons: * **Sensory (afferent):** These neurons are located in the peripheral nervous system (PNS) and transmit sensory information to the central nervous system (CNS). * **Interneurons:** These neurons are located in the CNS and communicate signals between sensory and motor neurons. They receive information from both sensory and motor neurons. * **Motor (efferent):** These neurons are located in the CNS and transmit motor messages away from the CNS. To muscles and glands. Sensory neurons transmit information *to* the CNS, interneurons communicate *within* the CNS, and motor neurons transmit information *from* the CNS.
