The<unk><unk>  () 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. The word<unk><unk>  (plural: latissimi<unk>  comes from Latin and means "broadest muscle of the back", from<unk> " ()' and "dorsum" (). The pair of muscles are commonly known as "lats", especially among bodybuilders. The<unk><unk>  is the largest muscle in the upper body. The<unk><unk>  is responsible for extension, adduction, transverse extension also known as horizontal abduction (or horizontal extension), flexion from an extended position, and (medial) internal rotation of the shoulder joint. It also has a synergistic role in extension and lateral flexion of the lumbar spine. Due to bypassing the scapulothoracic joints and attaching directly to the spine, the actions the latissimi<unk>  have on moving the arms can also influence the movement of the scapulae, such as their downward rotation during a pull up.
