Neurones. Coloured transmission electron micrograph (TEM) of a section through healthy human neurones (nerve cells) in a ganglion. A ganglion is a grouping of nerve cells outside the brain and spinal cord. Each neurone consists of a cell body,in which a nucleus (pink) is found,along with various nerve fibres (not seen) down which impulses (messages) travel. The neurone is insulated by a myelin sheath (green),which improves the efficiency of nerve transmission. Axon nerve fibres are the output processes,while branching dendrites are the neurone's sensory receptors. Magnification unknown | |
