The signal comes from the brain, down the spinal cord, and down to the nerve cells that need to send the stimulus signal. The signal also runs vice versa, up the spinal cord and into the brain.
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.
A group of nerve cells all together is called a ganglion. These nerve cells are linked by synapses and attach to a nerve fiber.
The slowest dividing cells in the human body are the nerve cells. Nerve cells generate and conduct electrical impulses, allowing communication between the central nervous system and the rest of the body.

Nerve impulses are carried by neurons and passed to other neurons at junctions called synapses. cells pass messages The signal may be directly transferred or can be carried across the gap by chemicals called neurotransmitters.

Nerve conduction velocity studies (NCV) are used to measure the speed with which an electrical signal is transferred along the nerve.
Association neurons
no nerve cells are like a chain one feeels it passes the signal to the next all the way up to your brain

This question could probably be asked more clearly. Myelinization of a nerve fiber helps the nerve's signalpropagate more quickly. Think of the nerve cell as a length of wire, and the myelin as the rubber insulation on the wire. Each nerve cell allows an electrical signal to pass down it's axon. If there is insulation around the nerve (myelin) then the signal is contained within the nerve cell, and passes quickly to the end of the nerve cell. Demyelinated nerve cells do not have this insulation keeping the electrical signal in the cell; so the signal can travel to adjacent cells. The net effect is that the signal either never reaches the end of the intended axon (such as with multiple sclerosis), or the signal takes longer to get there. Some nerve cells (grey matter, for example) are not intended to be myelinated. These cells are designed to act without insulation, so either the signal is supposed to travel to adjacent cells, or it is supposed to take relatively longer to reach the end of the axon.
