Question

Quizplus · Accepted Answer

A single Schwann cell can only wrap its plasma membrane around one axon to form the myelin sheath. This allows for effective insulation and faster propagation of nerve impulses along the axon. In contrast, oligodendrocytes in the central nervous system can myelinate multiple axons simultaneously, which is one of the key differences between the myelin sheaths in the peripheral and central nervous systems.
