Neural information system is complexity built from simplicity. Building blocks are neurons, or nerve cells. Each consists of a cell body and its branching fibers that receive messages and conduct impulses toward to cell body (dendrites) The cells lengthy axon fiber passes the message through its terminal branches to other neurons or to muscles or glands. Axons are encased in a myelin sheath a layer of fatty tissue that insulates them and speeds their impulses.
