Explanation: Saltatory conduction (from the Latin saltare, to hop or leap) is the propagation of action potentials along myelinated axons from one node of Ranvier to the next node, increasing the conduction velocity of action potentials Ref: guyton and hall textbook of medical physiology 12 edition page number:71,72,73
