sheath of Schwann
http://purl.obolibrary.org/obo/UBERON_0001031
The outermost nucleated cytoplasmic layer of Schwann cells that surrounds the axon of the neuron. It forms the outermost layer of the nerve fiber in the peripheral nervous system. The neurolemma is underlain by the basal lamina (referred to as the medullary sheath in the included illustrations. In CNS, axons are myelinated by oligodendrocytes, thus lack neurolemma.

FMA def is 'Neural tissue which consists of Schwann cells' which does not fit, but we still use 'neural tissue' here. WP def specifically states Schwann cells, which would restrict it to PNS
