Lateral shoulder raises, shown below, increase a person’s risk for subacromial impingement syndrome (SIS), which is the impingement of the soft tissues, namely rotator cuff tendons and bursa, between the bony structures of the shoulder during shoulder abduction. This is because of the large forces generated by the deltoid muscle, shown in red (anterior portion), green (middle portion), and blue (posterior portion) to lift the arm up. This generates large joint reaction forces of the scapula pressing on the humeral head. In order to draw a free body diagram for this problem, we need to pay close attention to the point of application each force, and the direction of each force. Which of the following statements are true?
