A nursing student is reviewing the role of osteoclasts in bone metabolism. Which function is primarily associated with osteoclasts

A. Hinge joint:Hinge joints allow movement primarily in one plane and do not provide the widest range of motion.
B. Pivot joint:Pivot joints allow rotation around a single axis and are limited compared with multiaxial joints.
C. Ball and socket joint:Ball-and-socket joints, such as the shoulder, permit movement in multiple axes including rotation, providing the widest range of motion.
D. Saddle joint:Saddle joints allow biaxial movement but do not match the multiaxial freedom of a ball-and-socket joint.

A. Muscle atrophy:Muscle atrophy is loss of muscle mass seen in disuse or neuromuscular disease rather than a hallmark of fibromyalgia.
B. Localized joint inflammation:Localized joint inflammation suggests inflammatory arthritis, which differs from fibromyalgia’s noninflammatory pain.
C. Widespread musculoskeletal pain:Widespread musculoskeletal pain, often accompanied by fatigue and sleep disturbance, is a defining feature of fibromyalgia.
D. Skin rashes:Skin rashes are not a typical symptom of fibromyalgia and point toward dermatologic or systemic inflammatory conditions.
