Discovered by French scientist Louis-Antoine Ranvier in 1878, these tiny nodes have been known since 1939 to act like relay stations placed about 1 millimeter apart along the myelinated nerve to ...

The three best examples of ion channel/receptor clustering in the nervous system are found at the synapse, the node of Ranvier, and the axon initial segment (AIS). In the case of the synapse, the ...

Myelin surrounds and insulates the axon and builds specialized molecular structures at small, uncovered gaps in the sheath, which are referred to as the nodes of Ranvier. In the case of ...

Myelin insulates the axon by assembling specialized structures at the nodes of Ranvier. This myelination of nerves greatly increases the speed that signals (referred to as action potentials ...

Along the axons, the myelin sheath is regularly interrupted by structures referred to as the nodes of Ranvier, and its insulating effect ensures that action potentials can be built up (i.e. signal ...

Line scan of the intensity measured in places where myelin ensheaths an axon. (Right) In vivo imaging of nodes of Ranvier. a) Diagram demonstrating in vivo two-photon imaging through a cranial window ...

Together with the electrically insulating myelin sheath, the so-called nodes of Ranvier form a basis for electrical nerve impulses to be transferred very rapidly over longer distances. They “jump” ...
