You don't, but glial cells, (oligodendrocytes in the CNS, and Schwann cells in the PNS), wrapped one after another around the axons of neurons with gaps between them called the nodes of Ravnier do create myelinated neurons.

Impulses from the sense organs travel to the brain along nerve fibers known as sensory neurons. These neurons carry the signals to the brain, where they are processed and interpreted to create our perceptions and sensations.
sensory neurons
Sensory Neurons
Sensory neurons and neurons are connected by Interneurons.
Afferent Neurons
Interneurons or association neurons.
Motor neurons and intern neurons
The neurons form the bodies nervous system.
Sensory Neurons
Interneurons or association neurons are connector neurons that establish connections between other neurons.
These are called efferent neurons. The one that carry impulses away are afferent. Afferent (A) are away (A).
