They have a long extension called an axon that is enclosed by a coating of myelin (generated by a different cell type) capable of acting much like a coaxial cable in electronics, rapidly propagating an excitation signal voltage pulse to the synapse where it is transferred chemically to another nerve cell.

Nerve cells are a part of the nervous system. There are nerve cells all around the body. Without nerve cells your body would not function the way it does.
chess in the main function
Nerve cells have many adaptions that make them functional. Some of these adaptions include longer axons in order to deliver action potentials a long distance. The dendrites carry the nerve impulses to the cell body. The myelin sheath increases the rate of transmission of nerve impulses.

they transfer nerve impulse to the brain which allows brain to function
Nerve cells are specialized cells for neuron function by bio chemical ion diffusion to transmit electrical impulses as information from neural cortices to muscles/organs for coordination of body function.
The nerve cells have fine extensions which are usually excitable cells in the nervous system. There function is to transmit and process information.
Nerve cells can send and receive messages. Thus they can control movements and they sensory function. Some may be assigned to one or another.
