The Latissimus Dorsi also known as the lats, is a large, flat muscle on the back that stretches to the sides, behind the arm, and is partly covered by the trapezius on the back near the midline. Functionally, the latissimus dorsi muscle belongs to the muscles of the scapular motion. This muscle can pull the inferior angle of the scapula in various directions, producing movements on the shoulder joint (internal rotation, adduction, and extension of the arm). Its wide attachment involving multiple points of attachment and the multidirectional orientation of its muscle fibers allow the lats to help with several vital movements. This muscle plays a vital role in activities like climbing, rowing, and swimming.
