Soma the cell body, control centre of the neuron, has dna, produces everything the neurons need to survive, grow repair, function. Dendrites 2 main functions: increase surface area of the soma, receive messages from other neurons. Axon carries out messages is the main job, carries out action potential, electrical/nerve impulse. Axon/terminal branches - allow the flow of information for one neuron cell to more than one cells.
