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?
I read that the latissimus dorsi muscle twists upon itself, what does that mean?
According to anatomical descriptions, 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". This means that the muscle has a double twist, with certain fibers crossing over others at different points.
