I know axons carry the electrical signal away from the body and have to be myelinated for some reason, but how come dendrites aren't mylinated when the impulse is going into the neuron body?
Also, speaking of this where are these neurons located exactly? In your arm, leg, ?? are motor neuron and sensory located in the same location?
Thank you!

If you think of dendrites as the processes taking information to the cell body, then the peripheral sensory neurons have myelinated dendrites.
Short dendrites in the central nervous system are not myelinated because they need to integrate information from many inputs and the lengths of the dendrites are small.

The cell bodies for the peripheral sensory neurons are located in the dorsal root ganglia outside the spinal cord.  The cell bodies for the peripheral motor neurons are located in the ventral horns of the spinal cord.
