Degeneration and regeneration in the insect central nervous system

Reactive Axons show non-degenerative morphological changes in the portion of connective between the injury and ganglion (the reactive segment of the connective). Degenerating Axons lose axoplasmic integrity, show autolytic changes, and are gradually phagocytosed during the first twelve days after injury. Regenerating Axons form new tissue distal to the reactive region; this is the regenerating portion of the connective. A Neuroma forms when growth from out axon tip is directed back into the reactive portion of the connective.
