• Surface is smooth

• Cylinder-shaped and elongated

• Attached to bones

• Works involuntarily

Multiple Choice

Which of the following statements about muscle contraction is correct?

• Muscle contraction involves only actin.

• Muscle contraction causes the muscle to shorten and thicken.

• Relaxation is when the muscle contracts.

• Tetanus is a relaxed muscle state.

Multiple Choice

Which structure is the smallest functional unit of a muscle, responsible for contraction?

• Muscle

• Muscle fibers

• Sarcomere

• Myofibril

Open Ended

Describe the hierarchical organization of muscle from the whole muscle to the molecular level, including the role of actin and myosin.

Multiple Select

Which of the following are components of a thin filament in muscle fibers?

• Actin

• Troponin

• Tropomyosin

• Myosin

Open Ended

What changes occur in the sarcomere during muscle contraction compared to relaxation?

Multiple Choice

Which statement best describes the role of calcium ions in muscle contraction?

• Calcium ions bind to actin to initiate contraction.

• Calcium ions cause the release of ATP from myosin.

• Calcium ions enable the binding of myosin to actin by exposing binding sites.

• Calcium ions are absorbed by the sarcomere during contraction.

Multiple Choice

Which ion is released in the muscle when acetylcholine acts, and what is its role in muscle contraction?

• Calcium; stimulates actomyosin formation

• Sodium; triggers muscle relaxation

• Potassium; increases muscle tension

• Magnesium; inhibits contraction

Multiple Select
