What is happening to a neuron that is undergoing Wallerian degeneration?
What will be an ideal response?
The process of Wallerian degeneration occurs when the axon distal to the site of injury of a nerve deteriorates and macrophages migrate in to phagocytize the debris. The Schwann cells in the area then divide and form a solid cellular cord that follows the path of the original neuron. If the neuron recovers, its axon will regrow into the site of the injury and the Schwann cells will wrap around it.
