A skeletal muscle is examined under a microscope. Which structure is a bundle of muscle fibres within the muscle?
Correct answer: A. Fascicle
- A. Fascicle
- B. Myofilament
- C. Sarcolemma
- D. Motor end plate

About Skeletal and Muscular Systems
The skeletal and muscular systems include bone structure, joints, cartilage, the axial and appendicular skeleton, and the roles of ligaments and tendons. They also cover skeletal muscle organization, the sliding filament mechanism, neuromuscular contraction, and common differences between voluntary skeletal muscle, cardiac muscle and smooth muscle.
