What Histological Changes Occur During Regeneration?
Histological examination reveals several changes during neural regeneration. Following injury, there is an initial phase of Wallerian degeneration, where the distal axon segment degenerates. This is followed by the proliferation of glial cells and the formation of a glial scar. In the PNS, axons sprout new growth cones that navigate through the Schwann cell pathways.
