A nurse reviews the function of osteoclasts with a patient who has increased bone resorption. Which statement is accurate?
Correct answer: B. They break down mineralised bone tissue
- A. They form new cartilage at joint surfaces
- B. They break down mineralised bone tissue
- C. They produce collagen for skeletal muscle
- D. They store calcium inside muscle fibres
Explanation
Osteoclasts resorb bone by dissolving mineral and degrading the organic matrix. Osteoblasts build bone, while cartilage cells and muscle fibres have different functions.

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.
