Attached is a painting I did, demonstrating the overall nervous system in the middle. The nerve cells on the left side of the painting show a healthy string of neurons, with myelin sheaths and oligodendrocytes intact. On the right, depicted is the degenerative effects a disease like Multiple Sclerosis can have. The oligodendrocytes have been destroyed by an autoimmune response, leaving lesions where the myelin sleeves once were, and causing degenerative neural issues like blindness and (eventually) paralysis.
