Schwann cell and myelin sheath
WebMyelin sheath is also known as medullary sheath. It is an insulating layer which covers the axon and helps to maintain a constant membrane potential. It is produced by Schwann cell in the peripheral nervous system and from oligodendroglia cells. So, the correct answer is option B.
