Some Nerves Are Myelinated, and Others Are Not

Essay

Some nerves are myelinated, and others are not. Myelinated nerves send signals faster than unmyelinated neurons. Draw two neurons of equal length, and wrap segments of myelin along one. Be careful to leave spaces for the nodes of Ranvier. Now, measure the exposed axons of each, and total up the distance. Describe why the myelinated neurons send signals faster.
