Damaged axons can be repaired in the body,but not in the brain or spinal cord.Only ______ cells generate axonal regrowth after an injury.

Question

Quizplus · Accepted Answer

Schwann cells in the peripheral nervous system have the ability to generate axonal regrowth after an injury by producing a pathway for axon growth and secreting growth factors. Neurons and stem cells may be involved in recovery after injury in the brain and spinal cord, but they do not generate axonal regrowth directly. Red blood cells have no role in axonal regrowth after injury.
