Upper arm and shoulder anatomy

    • Which muscle abducts the upper arm?

      The rotator cuff is a set of four muscles that serve to stabilize and rotate the shoulder, attached by strong tendons to the upper head of the humerus. During abduction, the supraspinatous and infraspinaoous muscles abduct and rotate the head of the humerus.

    • What causes shoulder pain in upper arm?

    • Why does the muscle in my upper arm hurt?

      A strain injury is a common cause of upper arm muscle achiness. This injury occurs when a muscle and/or its associated tendon is overstretched, leading to tearing of the fibers. Strain injuries range from mild to severe, depending on the extent of tearing. A complete tear, or rupture, is the most severe type of strain injury.

Due to its S-shape, the outer end describes a much larger rotation during arm elevation than its inner end. Therefore, lesions of the acromio-clavicular joint ligaments are more frequent than are lesions of the sternoclavicular joint ligaments.
