Anatomy of the Elbow
The elbow is the joint that connects a person’s forearm with the upper arm.  The joint is formed where the humerus meets the radius and the ulna.  In addition to allowing the forearm to bend and extend it also allows rotation.  (This is what allows you to rotate the palm of the hand up and down.)

The elbow forms from the expansion of the lower end of the humerus into two thick knobs, or condyles: the humerus' dome-shaped lateral condyle articulates with a shallow depression on the end of the radius, and the humerus' spool-shaped trochlea fits into a notch in the ulna. Flexion and extention of this joint chifely involves only the humerus and ulna. Rotation of the forearm involves the smaller radius bone as well.

The elbow is especially susceptible to stress injuries either acutely, as the a result of a specific one time injury, or over time as the result of overuse and repetitive injuries.
