The human brain has approximately 100 billion neurons.To learn how neurons carry messages, read about the action potential.owever, neurons differ from other cells in the body because: 1  Neurons have specialize cell parts called dendrites and axons. 2  Neurons communicate with each other through an electrochemical process. 3  Neurons contain some specialized structures (for example, synapses) and chemicals (for example, neurotransmitters).
