Muscle Tissue Quiz

Which type of muscle tissue is attached to bones and is voluntarily controlled?

• Cardiac muscle

• Smooth muscle

• Skeletal muscle

• Involuntary muscle

What is the primary function of cardiac muscle?

• Digestion

• Pumping action of the heart

• Voluntary movement

• Connecting muscles to bones

Where is smooth muscle typically found?

• Attached to bones

• In the heart

• In the walls of internal organs

• Surrounding muscle fibers

What is the function of fascia in muscle tissue?

• Surrounds whole muscle

• Connects muscle to bone

• Thin covering of connective tissue around a muscle

• Cytoplasm of muscle fiber

Which connective tissue surrounds the whole muscle and lies beneath the fascia?

• Perimysium

• Endomysium

• Epimysium

• Sarcolemma

What is the functional unit of a muscle that produces striation in repeating patterns?

• Myofibrils

• Sarcomeres

• Actin

• Myosin

Which structure in the muscle cell stores calcium?

• Transverse tubule

• Sarcoplasmic reticulum

• Myofibril

• Neuromuscular junction

What protein composes thick filaments in muscle fibers?

• Actin

• Troponin

• Myosin

• Tropomyosin

Which proteins are associated with thin filaments to prevent cross-bridge formation when the muscle is not contracting?

• Myosin and actin

• Troponin and tropomyosin

• Sarcomeres and myofibrils

• Calcium and ATP

What is the role of the neuromuscular junction?

• It stores calcium in the muscle cell.

• It is the site where an axon of a motor neuron and skeletal muscle fiber interact.

• It composes the thick filaments.

• It prevents cross-bridge formation.
