Unmyelinated Axons EM

Schwann cells and oligodendrocytes can also associate with axons but not wrap them in myelin sheaths. This EM image shows a Schwann cell associated with several small axons but without myelinating the axons. In unmyelinated nerves, Schwann cells can associate with several axons; whereas in myelinated nerves, Schwann cells associate with only one axon.
