Spinal Cord Histology - Grey Matter

Most neurones have a light, large nucleus with a distinct nucleolus. The cytoplasm of many neurones contains fairly large amounts of rough endoplasmatic reticulum, which may aggregate within the cytoplasm of the neurone to form Nissl-bodies. Nissl-bodies are prominent in motor neurones located in the ventral horn of the grey matter of the spinal cord. The neurites are difficult to identify in most types of stained sections. Only the most proximal segments of the primary dendrites are seen clearly. The size of the perikaryon depends on the level of activity of the neurone and the length of the processes which the neurone has to support. An usable range for the size of the perikaryon would be 15 - 50 µm, although much smaller and much larger neuronal perikarya exist. (text Blue histology)
