The latissimus dorsi muscle, commonly referred to as the lats, primarily inserts at the intertubercular groove of the humerus. This large, flat muscle originates from the lower back, specifically from the spinous processes of the lower thoracic vertebrae, lumbar vertebrae, and the iliac crest. Its insertion allows the lats to play a crucial role in movements such as adduction, extension, and internal rotation of the shoulder joint.
