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 (yellow-green,containing nucleus) & processes of 2 types: a single axon,or nerve fibre,which is the effector part of the cell that terminates on other neurones or organs; & one or more dendrites,smaller processes that act as sensory receptors. Similar types of neurones are arranged in layers in the cerebral cortex. Magnification: x162 at 35mm size | |
