The latissimus dorsi muscle is "twisted upon itself, so that the superior fibers become at first posterior and then inferior, and the vertical fibers at first anterior and then superior". Does it mean that this muscle double twists in an arm flexation instead of untwist?
Can you tell me more about the latissimus dorsi muscle?
Sure! The latissimus dorsi is a large muscle that extends from the spine to the humerus and is responsible for moving the upper arm towards the body and rotating it inward.
