The nervous system is composed of neurons or nerve cells and their supporting structures. Types of Neurons There are three classes of neurons; each class corresponds to a different aspect of nervous system function. Sensory Neurons. Sensory or afferent neurons are specialized to detect stimuli and transmit information about them to the central nervous system. These neurons may connect any organ to the central nervous system. A stimulus is a change in the environment; it may be light, heat, pressure, or a chemical, for example.
