Nervous System

How many different types of neurons are found in nerve tissue?

The three main types of neurons are as follows: Sensory neurons conduct impulses from sensory organs (eyes, ears, surface of the skin) into the central nervous system. Motor neurons conduct impulses from the central nervous system to muscles or glands. Interneurons (or association neurons) are neither sensory neurons nor motor neurons. They permit elaborate processing of information to generate complex behaviors and comprise the majority of neurons in the central nervous system.
