The above image shows a higher magnification view of the grey matter of the spinal cord which is clearly surrounded by white matter. The ventral horn has a number of processess which extend into the white mater. The image displays a number of multipolar cells that are relatively large compared to the nerve fibres which surround these cells. Although at this magnification it is not possible to definitively identify these cells but it is likely that they are cell bodies of neurons. The surrounding nerve fibres are likely to be neuroglial cells, although the cytoplasm of these cells is not visible. The seemingly poor organisation of the tissues surrounding these neurons is often referred to as '''neuropil'''.

This image shows a further magnified view which displays the central canal and [[Ependymal_Cells#Ependymal_Cells|ependymal cell]] layers. The surrounding tissue is similar to that of the grey matter neuropil seen in the previous image above. Within the central canal vessel some remnants of [[Cerebral_Spinal_Fluid_-_Anatomy_%26_Physiology|CSF]] can be seen. Within the neuropil tissues some cell bodies can be seen.
