Ranvier's node (node of Ranvier, neurofibril node)

Regularly spaced gaps in the myelin sheath enveloping an axon. size: 1 uM in length, circumferential The axonal membrane is exposed to extracellular fluid at the nodes of Ranvier. The combination of the myelin sheath with regularly spaced nodes of Ranvier gives rise to saltatory conduction of axonal nerve impulses. Proteins implicated in formation of nodes of Ravier: - gliomedin, NRCAM
