C) motor units
D) myofibrils

Question

Quizplus · Accepted Answer

Skeletal muscle is composed of bundles of muscle fibers called fasciculi. The fasciculi are surrounded by connective tissue called perimysium, which separates the bundles and contains blood vessels and nerves. The entire muscle is further surrounded by epimysium, another layer of connective tissue that provides additional support and protection. Motor units refer to a single motor neuron and all the muscle fibers it innervates, while myofibrils are the contractile elements within a muscle fiber.
