Anatomy of the Elbow
The elbow is a hinge joint, which means the motion of the elbow is limited to one plane or direction. The elbow consists of three bones. These three bones are the humerus, radius and ulna. The radius and ulna are the two bones that help makeup the forearm. These bones are slightly curved and attached to many muscles in the arm. The ulna is larger and longer then the radius.
The inside area of your elbow, closest to your body, features the ulnar collateral ligament, which provide much of the density and stability to the elbow joint.
The Importance of the Elbow
The motion of the elbow aids you with rotating the forearm, intricate hand motions, and increases power to the upper body. Elbow injuries are easily ignored and to some, may not seem as serious compared to an injury to the knee or hip. If left untreated, injures to the elbow can have long-term detriments.
