9-36 Nervous tissue

Ganglia are clusters of neurons of the peripheral nervous system enveloped by a thin layer of dense connective tissue.

This image of a ganglion section shows numerous cells with bluish (basophilic) cytoplasm, large nuclei with loose chromatin, and voluminous strongly stained nucleoli. These are cell bodies of neurons.

The neurons of ganglions are surrouned small cells that cover them, called neuronal satellite cells or glial satellite cells. They become highlighted in green when you hover the cursor over or click on the image.
