In multiple sclerosis, the conduction of nerve impulses is severely impaired due to the

A. Destruction of the myelin sheath in the central nervous system
✓
B. Depletion of neurotransmitter vesicles
C. Hyperactivity of acetylcholinesterase
D. Blockage of voltage-gated calcium channels

📝 Explanation

Multiple sclerosis is an autoimmune disorder characterized by the progressive demyelination of axons in the CNS, which disrupts saltatory conduction and leads to severe neurological deficits.

📖 Additional Information
