Question

Which of the following statements is correct for node of Ranvier of neuron?
(1) Neurliemma is discontinuous
(2) Myelin sheath is discontinuous
(3) Both neurilemma and myelin sheath are discontinuous
(4) Covered by Myelin sheath

Answer 1

Answer:

4

Explanation:

The long, myelin-covered section of axon between nodes is the internode. The purpose of the myelin sheath is to increase the speed of transmission by acting as an electrical insulator. In non-myelinated axons, the action potential must propagate continuously along the plasma membrane.J
