Regeneration of peripheral axons requires
A) construction of a collateral that branches from the point of damage.
B) deposition of neurofilaments to bridge the gap between the original axon fragments.
C) formation of a tube by Schwann cells to guide growth.
D) migration of neural stem cells from the hippocampus.

Question

Quizplus · Accepted Answer

Regeneration of peripheral axons requires the formation of a tube by Schwann cells to guide growth. Schwann cells form a basal lamina tube to create a path for the regrowing axon. This tube provides a path of least resistance, and the neurite grows into the tube and elongates, forming a new axon.
