Neural messages travel faster on axons that __________.
A) are polarized
B) are not exposed to acetylcholine (ACh)
C) are located in the hypothalamus
D) have a myelin sheath

Question

Quizplus · Accepted Answer

Axons that are myelinated have a layer of fatty tissue that helps to insulate and speed up neural messages, allowing them to travel faster than unmyelinated axons. Polarization and location in the hypothalamus do not specifically impact the speed of neural messages, and exposure to acetylcholine may impact the ability of a neuron to send messages, but not necessarily the speed at which they are sent.
