GENERAL HISTOLOGY

Detailed explanation-1: -Nodes of Ranvier are microscopic gaps found within myelinated axons. Their function is to speed up propagation of action potentials along the axon via saltatory conduction . The Nodes of Ranvier are the gaps between the myelin insulation of Schwann cells which insulate the axon of neuron.

Detailed explanation-2: -Answer and Explanation: A gap between Schwann cells in the peripheral system is called a node of Ranvier. This is important in saltatory conduction where the action potential propagation speed is much faster compared to continuous conduction.

Detailed explanation-3: -The action potential propagated by one node of Ranvier jumps to and is regenerated at the next node along the axon, thereby enabling the action potential to travel rapidly along the fibre.
