Question

Quizplus · Accepted Answer

Pennate muscles produce greater force than fusiform muscles due to their increased number of fibers in a smaller cross-sectional area. Additionally, parallel muscles can generate more force than series muscles because they have more fibers in parallel which allows for a greater total cross-sectional area. Therefore, the muscle orientation that would be able to produce the greatest amount of force would be parallel, with pennate architecture for increased force production.
