The cell body of a neuron is supported by a complex meshwork of structural proteins called neurofilaments, which are assembled into larger neurofibrils. Some neurons also contain pigment granules, such as neuromelanin (a brownish-black pigment, byproduct of synthesis of catecholamines) and lipofuscin (yellowish-brown pigment that accumulates with age).
4. Ependymal cells. These cells line the vetricles and spinal canal. They have cilia on their luminal surface. This diagram shows a schematic arrangement of neurons and the four types of supporting cell in the central nervous system. All of these cells are found in the grey matter of the spinal cord. They are quite difficult to recognise in H&E sections, as you can see here, where only astrocytes can reliably be identified.
