The document provides information about the pectoral girdle (shoulder girdle) and associated bones, joints, muscles and movements. It describes the clavicle bone, its articulations in the sternoclavicular and acromioclavicular joints. It also describes the scapula bone and its movements. Key muscles that act on the pectoral girdle and humerus are identified, including their origins, insertions and actions. The major joints of the pectoral girdle, the sternoclavicular and acromioclavicular joints, are also summarized.

30. Elevation of Scapula Superior movement of the shoulder girdle; moving the scapula up.

31. Depression of Scapula Inferior movement of the shoulder girdle; moving the scapula down.

32. Movements of the Scapula

33. Upward Rotation of Scapula Rotary movement of the scapula; moving inferior angle of scapula laterally and upward

34. Downward Rotation of Scapula Rotary movement of the scapula; moving inferior angle of scapula medially and downward.

35. Movements of the Scapula

36. Abduction/Protraction of Scapula Forward movement away the midline of the body; moving the scapula away from the spine during protraction of the shoulder girdle.

37. Adduction/Retraction of Scapula Backward movement toward the midline of the body; moving the scapula back toward the spine during retraction of the shoulder girdle.
