Slide 3: Multipolar neurons- sympathetic ganglion. Note the very incomplete appearing satellite layer. Groups of fibers intermingle and do not form the neat bundles of processes seen in the DRG. Note the large number of dendritic processes and brown "age" pigment (globules in the cytoplasm). This is "wear and tear" pigment, a build-up of residual bodies during aging, especially in nervous tissue and muscle which are generally long-lived non-dividing cells. Recall that lipofuscin granules are derived from secondary lysosomes. Human - Bodian stain.
