Myelin sheath. (Science: anatomy, neurology) An insulating layer surrounding vertebrate peripheral neurons, that dramatically increases the speed of conduction. It is formed by specialised schwann cells, that can wrap around neurons up to 50 times.
17 Contributions.   Surrounding the myelin sheath, there is a thin membrane called neurilemmal sheath. This is also called neurilemma or sheath of Schwann. This contains Schwann cells, whicâ¦h have flattened and elongated nuclei. The cytoplasm is thin and modified to form the thin sheath of neurilemma enclosing the myelin sheath.   One nucleus is present in each internode of the axon.
