Muscular System Quiz

Which connective tissue wraps the entire skeletal muscle, holding all fascicles together?

• Sarcolemma around myofibrils

• Endomysium around each fiber

• Epimysium around whole muscle

• Perimysium around fascicles

What is the correct order of skeletal muscle units from largest to smallest?

• Muscle, fiber, fascicle, sarcomere, myofibril, myofilaments

• Muscle, fascicle, fiber, myofibril, sarcomere, myofilaments

• Fascicle, muscle, fiber, myofilaments, sarcomere, myofibril

• Fiber, muscle, fascicle, myofibril, myofilaments, sarcomere

Which structure is a single muscle cell?
