The human body is made up of trillions of cells. Cells of the nervous system, called nerve cells or neurons, are specialized to carry messages through an electrochemical process. The human brain has approximately 100 billion neurons.To learn how neurons carry messages, read about the action potential. Neurons come in many different shapes and sizes.ells of the nervous system, called nerve cells or neurons, are specialized to carry messages through an electrochemical process.
