Question

Quizplus · Accepted Answer

Myelinated axons are faster at transmitting signals and can carry pain information more quickly than unmyelinated axons. Therefore, when Angelica plunges her hand into ice water, the pain information would be carried by myelinated axons that transmit the sensation quickly. On the other hand, when Erica sprains her ankle, the pain information would be carried by unmyelinated axons that transmit the sensation more slowly, leading to pain that can last for weeks.
