Web(A) Overview of the myelinated axonal domains in the CNS and PNS. The upper half shows an axon that is myelinated by a Schwann cell, including the basal lamina, microvilli, Schmidt-Lanterman incisures, sodium (Na +) channels and potassium (K +) channels, and myelin proteins that are highly abundant in the PNS. WebMyelinated nerve fiber layer is a developmental anomaly that results from an abnormal extension of myelination anterior to the lamina cribrosa of the sclera.1 In normal fetal development, myelination of the optic nerve begins at the lateral geniculate body, progresses toward the eye, and stops posterior to the lamina cribrosa prior to birth.
