The nervous system is the highway along which your brain sends and receives information about what is happening in the body and around it. This highway is made up of billions of nerve cells, or neurons (say new-rons) which join together to make nerves.1  A nerve is a fibre that sends impulses through the body.2  These fibres are covered by fatty substance called myelin (say my-e-lin). 3  Nerve cells work by a mixture of chemical and electrical action.his highway is made up of billions of nerve cells, or neurons (say new-rons) which join together to make nerves. 1  A nerve is a fibre that sends impulses through the body. 2  These fibres are covered by fatty substance called myelin (say my-e-lin). 3  Nerve cells work by a mixture of chemical and electrical action.
