Question

Why defects in the myelin sheath is dangerous?

• A. Action potentials would be conducted too slowly along the neurons
• B. Muscles would not contract when stimulated
• C. The thyroid gland would not be able to produce thyroxine
• D. The bone tissue would not be properly maintained

Answer 1

The correct option is A Action potentials would be conducted too slowly along the neurons

The myelin sheath of neurons provides them with an insulating covering. It allows rapid transmission of signals from the nervous system to the body and vice-versa. Any damage to the myelin sheath will cause hindrance and slowing down of the transmission of signals to the axons.

So, the correct answer is 'Action potentials would be conducted too slowly along the neurons'.
