Among invertebrates, increased speed along the axon is brought about by increasing the diameter of the axon. Among vertebrates, this same function (increased speed) is brought about by ____________________.

Question

Quizplus · Accepted Answer

In vertebrates, the speed of nerve impulse conduction along axons is increased by insulating the axons with myelin sheath cells. This myelination allows for faster transmission of electrical signals by enabling saltatory conduction, where impulses jump from one node of Ranvier to the next.
