Question

Quizplus · Accepted Answer

Muscle fibers in skeletal muscle form bundles called fascicles. This helps to organize and group muscle fibers together, which in turn helps to generate more force and movement when the muscle contracts. Myofilaments are protein filaments within the muscle fiber that actually generate the force of the contraction, while Z lines are the boundaries between individual sarcomeres (the functional unit within a myofibril). Myofibrils are the thread-like structures within the muscle fiber that contain the myofilaments, and epimysium is the outer layer of connective tissue that surrounds the entire muscle.
