WebThe Node of Ranvier is the 1-2 micrometre gap between the glial cells of the myelin sheath. These glial cells are called Schwann cells, and they help to electrically insulate the neuron. The Nodes of Ranvier are only present when the axon of a neuron is myelinated. WebNeurolemmocytes are the same as Schwann cells. They're called oligodendrocytes in the CNS. Gap junctions usually refer to connections between cells. Nodes of Ranvier are gaps in myelination where saltatory conduction can take place.
