Unmyelinated axons
In general, axons with diameters of less than one micron are not myelinated. Multiple axons indent the surface of a single Schwann cell and are surrounded by a single wrapping of the Schwann cell plasma membrane. These axons conduct at a slower velocity than their myelinated counterparts. 1000x, 15,000x
