The Individual nerve cell, comprised of the axon, dendrites, and cell body. 2. Many neurons In the nervous system? 0 86 billion 3. Function of cell body, dendrites, and axons. O Cell body: Contains the nucleus and other major components. O Dendrites: How Branch out from the cell body and receive messages from other neurons. O Axons: Carries messages away from the cell body to the dendrites. 4. Define popularization/ deportation, o Popularization: Resting state of neuron, semiprivate. Deportation: Stimulated state, neuron is no longer mostly negative on the inside. 5. How do neurons fire? O Sodium ions pump in, depopulating the axon, before the popularization returns. 1.
