False-colour scanning electron micrograph (SEM) of neurones (nerve cells) from the cerebral cortex - the outer,heavily folded,grey matter of the brain. Neurones exist in varying sizes & shapes throughout the nervous system,but all have a similar basic structure consisting of a large central cell body & processes of 2 types: a single axon (a nerve fibre) which is the effector part of the cell that terminates on other neurones (or organs),and one or more dendrites,smaller processes that act as sensory receptors. In the cerebral cortex,neurones of comparable structure are arranged in a variable number of layers. Magnification: x80 at 35mm size | |
