Uberon definition : 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.;
