Detailed explanation-1: -Schwann cell are cells in the peripheral nervous system that synthesize the myelin sheath around neuronal axons. Node of Ranvier are the periodic gap in the insulating myelin sheath on the axon of neurons that bring about the rapid conduction of nerve impulses. Thus the correct answer is option A.
Detailed explanation-2: -Gaps between adjacent Schwann cells of a myelin sheath are known as nodes of Ranvier.
Detailed explanation-3: -The Nodes of Ranvier are the gaps between the myelin insulation of Schwann cells which insulate the axon of neuron. The 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.
