Why does a pennate muscle generate more tension than does a parallel muscle of the same size?
A) A pennate muscle generates more tension because pennate muscle fibers lie parallel to the bone. B) A pennate muscle generates more tension because pennate muscle fibers lie perpendicular to the bone and parallel muscle fibers lie parallel to the bone. C) A pennate muscle generates more tension because a pennate muscle contains more muscle fibers than a parallel muscle. D) A pennate muscle generates more tension because a pennate muscle has a flat body and a parallel muscle has a broad body. E) A pennate muscle generates more tension because a pennate muscle pulls in only one direction and parallel muscles pull in different directions.
