Question:

Node of Ranvier occurs where?

Nerve is covered with myelin sheath

Neurolemma and myelin sheath are discontinuous

Neurolemma is discontinuous

Myelin sheath is discontinuous

Solution:

Myelin sheath is a fat layer formed by the Schwann cells that surround the axon. They are not continuous but leave gaps in between called the nodes of Ranvier. So, the correct answer is 'Myelin sheath is discontinuous'
