Muscle fibers can have various arrangements. The most powerful arrangement, in which more tension is generated during contraction, is called ________.

Question

Quizplus · Accepted Answer

Pennate muscles have shorter fibers that attach to a central tendon at an oblique angle, allowing for more muscle fibers to be packed into a smaller space and generate more tension during contraction. Circular muscles form a ring around an opening and can contract to close the opening, but their arrangement does not allow for as much tension generation. Parallel muscles have fibers that run parallel to the long axis of the muscle, but their arrangement does not allow for as much force production as pennate muscles. Convergent muscles have fibers that converge to a single point, but their arrangement does not allow for as much tension generation as pennate muscles.
