Spaces between adjacent schwann cells
Web26. mar 2024 · The tiny gaps between adjacent Schwann cells are called nodes of Ranvier. Nodes of Ranvier are the spots where the axolemma (the cell membrane of an axon) is exposed to the extracellular space. Because of the presence of nodes, nerve conduction in myelinated axons is referred to as saltatory conduction.
