Elbow Joint The elbow joint is a very complex hinge joint located between the distal end of the humerus in the upper region of the proximal ends of the ulna and radius. The elbow joint allows flexion and extension and rotation of the forearm and wrist. The range of motion of the elbow is limited due to the olecranon of the ulna so that elbow can only extend to 180 degrees. Like most synovial joints‚ a thin layer of articulating cartilage covers the ends of the bones to allow smooth movement.

An example of a pivot joint is the atlantoaxial joint‚ found between the C1 (atlas) and C2 (axis) vertebrae. Here‚ the upward projecting dens of the axis articulates with the inner aspect

The Shoulder Joint The glenohumeral joint‚ or as it is more commonly referred to the shoulder joint ‚ is one of the most flexible and unstable joints in the body.

There are two main bones that make up the shoulder
