The Neuron

In this video Paul Andersen explains the basic anatomy of a neuron; including the dendrites, cell body, axon hillock, axon, and axon terminal. He also describes how neurons are classified both structurally and functionally.

English: As a nerve impulse travels down the axon, there is a change in polarity across the membrane. The Na+ and K+ gated ion channels open and close in response to a signal from another neuron. At the beginning of action potential, the Na+ gates open and Na+ moves into the axon. This is depolarization. Repolarization occurs when the K+ gates open and K+ moves outside the axon. This creates a change in polarity between the outside of the cell and the inside. The impulse continuously travels down the axon in one direction only, through the axon terminal and to other neurons.
