Myelinated axons in human beings conduct action potentials about _________ unmyelinated axons in invertebrates.
A) as fast as
B) half as fast as
C) six times faster than
D) 24 times faster than

Question

Quizplus · Accepted Answer

Myelinated axons conduct action potentials up to 100 meters/second, while unmyelinated axons in invertebrates typically conduct action potentials at around 1 meter/second. Therefore, myelinated axons in human beings conduct action potentials 100 times faster than unmyelinated axons in invertebrates. 100/1 = 100 or 10^2. Therefore, myelinated axons in human beings conduct action potentials 24 times faster than unmyelinated axons in invertebrates.
