Detailed explanation-1: -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.
Detailed explanation-2: -The gap between myelin sheath are called nodes of Ranvier.
Detailed explanation-3: -In neuroscience and anatomy, nodes of Ranvier (/ˈrɑːnvieɪ/ RAHN-vee-ay), also known as myelin-sheath gaps, occur along a myelinated axon where the axolemma is exposed to the extracellular space.
Detailed explanation-4: -Gaps between adjacent Schwann cells of a myelin sheath are known as nodes of Ranvier. True.
