Fig. 14.2A. A microglial cell adjacent to a neuron in the primary visual cortex of a 5 year old monkey. This micrograph shows two important features of microglial cells, namely the long cisternae of rough endoplasmic reticulum and the fact when a microglial cell is adjacent to a neuron there is usually a thin astrocytic process (arrow) between the two cells.
Microglial cell- orange; dendrites- blue; axon terminals- green; dendritic spines- grey.
