The axon begins at the axon hillock and ends at the presynaptic terminal, which can branch into multiple terminals. The axon hillock is located where the cell body transitions into the axon. Dendrites branch out from the cell body, where the nucleus is located. The typical neuron consists of the dendrites, cell body, axon (including the axon hillock), and presynaptic terminal. The function of the neuron is dependent on the structure of the neuron. Their main function is to send electrical signals over short and long distances in the body, and they are electrically and chemically excitable.
Neurons are the basic units of the brain.
