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 similar basic structure; a large central cell body (coloured gold,containing nucleus) & 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),& 1 or more dendrites,smaller processes that act as sensory receptors. Similar types of neurones are arranged in layers in the cerebral cortex. Magnification: X 235 at 35mm size | |
