Which of the following neurons have the capacity for regeneration?
A) Unmyelinated neurons in the brain
B) Myelinated neurons in the spinal cord
C) Myelinated peripheral neurons
D) Postganglionic motor neurons

Question

Quizplus · Accepted Answer

Myelinated peripheral neurons have the capacity for regeneration due to the presence of Schwann cells, which can guide and support the regrowth of axons. Unmyelinated neurons in the brain and myelinated neurons in the spinal cord do not have the ability to regenerate because they lack a supportive environment for axon growth. Postganglionic motor neurons also do not have the capacity for regeneration.
