Nerve Impulses
It is a kind of coded signal that travels along the nerve membrane to stimulus cells-like muscle cells, hormone cells, gland cells etc. Using this nerve impulse the Nerve cells Communicate with other cells to perform a particular task and this coded signal relays on the Axon of the neuron.
