Question

The myelin sheath provides ......... to the axon.

• A. Mechanical support
• B. Electrical insulation
• C. Both A and B
• D. None of the above

Answer 1

The correct option is C Both A and B

The myelin sheath of a neuron consists of fat-containing cells that insulate the axon from electrical activity. This insulation helps to increase the rate of transmission of signals. Myelin is made up of inter-twining hydrocarbon chains of sphingomyelin, which serve to strengthen the myelin sheath. Hence it also provides mechanical support to the neuron.

Thus the correct option is C.
