False-colour scanning electron micrograph (SEM) showing neurones (nerve cells) in the human cerebral cortex - the outer grey matter of the brain. Neurones exist in varying sizes and shapes throughout the nervous system. A basic neurone consists of a cell body with processes of two types: a single axon (the output,effector nerve fibre) and one or more dendrites,smaller,input processes that serve as sensory receptors. In the cerebral cortex,neurones of comparable structure are arranged in a variable number of distinct layers. Magnification: x160 at 6x7cm size | |
