Main Page | See live article | Alphabetical index Neurolemma (spelled also neurolema, neurilemma and neurilema, and used interchangeably with epineurium) is the insulating myelin layer that surrounds an individual peripheral nerve fiber. The myelin is contributed by Schwann cells and the layer is sometimes referred to as the sheath of Schwann. The neurolemma is instrumental in regenerating axons that have been injured.
