How Do Neurons Transmit Nerve Impulses?

Answer

Neurons take in nerve impulses via the dendrites and transmit them through the cell body to the axon. When the dendrite receives a message or a stimulus, it excites the cell membrane via an electrical current. This action potential proceeds in segments towards the axon. Because one long line of transmission would slow the signal, the myelin sheath allows the signal to jump between segments, therefore speeding transmission. This type of signal transmission is called saltatory conduction. The segments of 2 mm allows the signal to travel up to 100 m/s.
