For instance, if you picked up a hot coal, it motor neurons innervating the muscles in your fingers would cause your hand to let go. Efferent neurons (also called motor neurons) get information from other neurons and convey commands to your muscles, organs and glands.For instance, if you picked up a hot coal, sensory neurons with endings in your fingertips would convey the information to your CNS that it was really hot Afferent neurons (also called sensory neurons) get information about what’s going on inside and outside of the body and bring that information into the CNS so it can be processed.There are three different classes of neurons that make up the nervous system: Nerves in the peripheral nervous system (PNS) carry information to and from neurons in the the central nervous system (CNS), where information is integrated and processed. Nerves are bundles of nervous tissue, often containing hundreds to thousands of axons wrapped in connective tissue. The nervous system is made up of neurons, specialized cells that can receive and transmit chemical or electrical signals, and glia, cells that provide support functions for the neurons by playing an information processing role that is complementary to neurons. A nervous system is an organism’s control center: it processes sensory information from outside (and inside) the body and controls all behaviors: from eating to sleeping to finding a mate. Even fundamental functions, like breathing and regulation of body temperature, are controlled by the nervous system. The visual system is processing what is seen on the page the motor system controls the click of the mouse and (if you’re lucky) the prefrontal cortex maintains your attention.

All Khan Academy content is available for free at When you’re reading this website, your nervous system is performing several functions simultaneously. The information below was adapted from OpenStax Biology 35.0 and Khan Academy Overview of neuron structure and function. Define learning and memory, and explain the roles of the hippocampus, the cerebral cortex, neuroplasticity, and synaptic plasticity in learning and memory.Describe the roles of and differentiate between the divisions of the vertebrate nervous system (afferent, efferent, somatic, autonomic, sympathetic, parasympathetic).Identify and describe basic structures and functions of the central and peripheral nervous systems.Describe different types of nervous systems in different animal lineages.
