The latissimus dorsa muscle, also known as the "lasts," is a large, triangular muscle located on the back of the upper body. It is responsible for a variety of movements, including shoulder extension, adduction, and medial rotation, as well as assisting in respiration. The latissimus dorsa muscle originates from the spinous processes of the lower thoracic vertebrae, the thoracolumbar fascia, the iliac crest, and the lower three ribs. From there, the muscle fibers converge to form a tendon, which attaches to the intertubercular groove of the homers bone in the upper arm.
