Question

Is myelin sheath present around the Schwann cell or Schwann cells are present around myelin sheath?

Solution

The Schwann cell in the peripheral nervous system produces myelin which the myelin shealth is made of.
So myelin shealth is present around Schwann cells.

A myelinated nerve fibre is enveloped by Schwann cells, which form a myelin sheath around the axon.

An unmyelinated nerve fibre is not enclosed by a Schwann cell and hence does not form a myelin sheath around the axon.
