Which structure allows a long bone to increase in length during childhood?
Correct answer: A. Epiphyseal plate
- A. Epiphyseal plate
- B. Medullary cavity
- C. Periosteum
- D. Articular capsule
Explanation
The epiphyseal plate contains cartilage that allows longitudinal growth of a long bone. After growth is complete, it becomes the epiphyseal line; the periosteum mainly supports growth in thickness and repair.

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.
