Which type of bone is longer than it is wide?

Correct Answer: C

Rationale: Long bones, like the femur or humerus, are longer than wide, designed for support and movement via levers. Short bones are cuboidal (e.g., carpals), flat bones are thin (e.g., skull), and irregular bones are complex (e.g., vertebrae). Long bones' length-to-width ratio, per bone classification, makes 'c' correct.

Correct Answer: A

Rationale: Facial bones include maxilla (upper jaw) and mandible (lower jaw), shaping the face (14 total). Humerus/femur are limb, scapula/clavicle are pectoral girdle, occipital/parietal are cranial not facial. Maxilla/mandible's facial role, per skull, makes 'a' correct.

Correct Answer: C

Rationale: Hyaline cartilage, smooth and glassy, forms costal cartilage in the rib cage, connecting ribs to sternum, flexible yet supportive. Elastic is in ears, fibrocartilage in discs neither fit ribs. Hyaline's prevalence, per thorax, makes 'c' correct.

Correct Answer: C

Rationale: ATP stores energy in its phosphate bonds, releasing it controllably for cellular work (e.g., muscle contraction), a universal energy currency. It results from catabolism , but that's not why it's important storage is key. It doesn't release energy uncontrollably , that's inefficient. Not all only 'c' fits. ATP's energy storage role, per biochemistry, makes 'c' correct.

Correct Answer: D

Rationale: The lumbar region (lower back) is superior to the popliteal region (behind the knee), per anatomical regions lumbar above, popliteal lower on the leg. It's superior to gluteal , superior to umbilical , inferior to cervical . Superiority to popliteal, per body mapping, makes 'd' correct.
