Chapter 10 Review Anatomy 10.1 - 10.6 - Muscle Muscular System

Muscle tissue, one of the four basic tissue groups, consists chiefly of cells that are highly specialized for

• conduction

• contraction.

• peristalsis.

• cushioning.

• secretion.

The dense layer of connective tissue that surrounds an entire skeletal muscle is the

• tendon.

• epimysium.

• endomysium.

• perimysium.

• fascicle.

Nerves and blood vessels that service a muscle fiber are located in the connective tissues of its

• endomysium.

• perimysium.

• sarcolemma.

• sarcomere.

• myofibrils.

The bundle of collagen fibers at the end of a skeletal muscle that attaches the muscle to bone is called a(n)

• tendon.

• epimysium.

• endomysium.

• perimysium.

• fascicle.

Interactions between actin and myosin filaments of the sarcomere are responsible for

• muscle fatigue

• the conduction of neural stimulation to the muscle fiber.

• muscle contraction.

• muscle relaxation.

• the striped appearance of skeletal muscle.

In a sarcomere, the central portion of thick filaments are linked laterally by proteins of the

• Z line.

• M line.

• H band.

• A band.

• I band.

The advantage of having many nuclei in a skeletal muscle fiber is the ability to

• contract much more forcefully.

• produce more ATP with little oxygen.

• store extra DNA for metabolism.

• produce large amounts of muscle proteins.

• produce nutrients for muscle contraction.

The repeating unit of a skeletal muscle fiber is the

• sarcolemma.

• sarcomere.

• sarcoplasmic reticulum.

• myofibril.

• myofilament.

The plasma membrane of a skeletal muscle fiber is called the

• sarcolemma.

• sarcomere.

• sarcosome.

• sarcoplasmic reticulum.

• sarcoplasm.

The region of the sarcomere containing the thick filaments is the

• Z line.

• M line.

• H band.

• A band.

• I band.
