Thorax - transverse section

You selected: latissimus dorsi

The latissimus dorsi muscle is one of the primary muscles of the back. It extends in a large traingle from the 6th thoracic vertebra (a point roughly between the scapulae) to the sacrum, and laterally to its attachment on the humerus of the arm. The muscle adducts the shoulders, done by military recruits standing at attention, and also extends the shoulder joint, an action used to raise the arm.
