From Latin dorsum (back) + epitrochlear (relating to the area beside the trochlea of the humerus). Anatomical term combining dorsal location with a specific arm landmark. Medical terminology.
The dorsoepitrochlear nerve is why sometimes your elbow gets a sharp, tingling sensation—it runs right past that bony bump on the outside of your elbow where you whack your funny bone!
