What is the difference between Schwann cells and Oligodendrocytes other than the location of where they wrap neurons in myelin?

Just curious while taking upper level physiology.

Morphologically, behaviorally, and physiologically, they're different cells.  Oligodendrocytes have many arms, which insulate many cells, whereas Schwann cells wrap around a single segment of a single axon.  Schwann's can create an architecture for growing axons, and come from a different lineage than oligodendrocytes.  Both cell types have non-myelinating versions ("satellite cells"), that serve different roles, some structural, and some regulate interstitial fluid.
