Answer:
All cells possess the ability to respond to stimuli. However, cells of the nervous tissue are highly specialized for being stimulated and then transmitted the stimulus very rapidly from one place to another within the body. The brain, spinal cord and nerves are all composed of the nervous tissue. The cell of this tissue are called nerve cells or neurons. A neurons consists of a cell body with a nucleus or cytoplasm, from which long thin hair-like parts arise. Usually each neuron has a single long part, called the axon, and many short, branched parts called dendrites. An individual nerve cell may be up to a meter long. Many nerve fibres bound together by connective tissue make up a nerve.
