Hi....
You probably think of your nervous system as a kind of computer network, or some kind of electrical system that passes nerve impulses around. But in reality, the miraculous journey of a signal thorough your nervous system is a story that involves cell biology, chemistry and physics. Your brain contains 30 billion neurons, and each of them is a staggering achievement.
Neurons are unique-looking little cells. Like all animal cells, a neuron has a cell body, called a soma, where the DNA-carrying nucleus sits, providing directions for the cell to make various proteins. In a neuron, however, this is just the beginning of the cell structure. On one end, the soma sprouts branch-like dendrites for receiving signals, while a long –- up to a meter long –- axon stretches away in the other direction, branching out into multiple axon terminals for sending signals.
Hope it helps you. :-)
