Correct answer: CSkeletal muscle
Skeletal muscles attach to bones and are generally controlled voluntarily, allowing movements such as walking, lifting, and running.
Correct answer: APectoralis major
The pectoralis major produces movements including flexion, adduction, and internal rotation of the upper arm, making it important in pushing actions.
Correct answer: BFlexion of the forearm
The biceps brachii contributes strongly to elbow flexion and also helps supinate the forearm.
Correct answer: DQuadriceps femoris
The quadriceps femoris consists of four muscles on the anterior thigh that primarily work together to extend the knee.
Correct answer: CTendon
Tendons are strong connective tissues that transmit force generated by muscles to bones, producing movement at joints.
Correct answer: ADiaphragm
When the diaphragm contracts, it moves downward and increases the volume of the thoracic cavity, drawing air into the lungs.
Correct answer: BSarcomere
Sarcomeres contain organized actin and myosin filaments whose interactions generate the force responsible for muscle contraction.
Correct answer: DAcetylcholine
Motor neurons release acetylcholine, which binds to receptors on the muscle fiber membrane and initiates electrical events leading to contraction.
Correct answer: BLatissimus dorsi
The latissimus dorsi extends and adducts the upper arm, making it especially active during pulling and climbing movements.
Correct answer: CIt exposes binding sites on actin by initiating regulatory protein movement
Calcium binds to troponin, causing a change that moves tropomyosin away from binding sites on actin so myosin can form cross-bridges.
