Structure of a nerve cell. Computer artwork showing the internal structure of a neuron (nerve cell). The cell's nucleus (sphere, centre) can be seen surrounded by endoplasmic reticulum (brown sheets) formed into a golgi apparatus (right). Numerous mitochondria (oval) can also be seen, which provide the cell with the energy it needs. The outer structure consists of numerous projections (axons and dendrites) that form the nerve fibres and connect to other nerve cells.
