'''''Shoulder Joint'''''

The shoulder joint links the humerus and the scapula at the '''glenoid cavity''', which is much smaller than the head of the humerus.  While structually it is a [[Joints - Anatomy & Physiology#Types of Joints|'''ball and socket''']] joint, it functions as a [[Joints - Anatomy & Physiology#Types of Joints|'''hinge joint''']] due to extensive muscling around the articulation.  The joint capsule is enlarged and extends under the tendon of the biceps, acting as a synovial sheath to protect the tendon.

'''''Elbow Joint'''''  

Movement of the elbow joint is restricted to the sagittal plane.  It is bounded medially and laterally by collateral ligaments betweek the humerus and radius, caudally by the olecranon ligament between the humerus and olecranon, and further enforced by the annular radial ligament.  The elbow is a compound joint including:
