What is the primary function of myelin sheaths surrounding vertebrate axons in peripheral nervous tissue?
Answer and explanation
Correct answer: B. Accelerating action potential propagation via saltatory conduction
- Step 1: Myelin acts as an electrical insulator produced by Schwann cells. Step 2. Action potentials jump rapidly between unmyelinated nodes of Ranvier, known as saltatory conduction. Answer: Accelerating action potential propagation via saltatory conduction. Why not the others: Neurotransmitters are synthesized in the soma and axon terminals, not in myelin.
