Which bone type is primarily involved in weight bearing?

• A. Long bones
• B. Short bones
• C. Flat bones
• D. Sesamoid bones

Answer: (B)

Long bones are designed to carry and transfer body weight, especially in the legs. Their long shaft provides strength to resist bending, while the ends widen to distribute load across joints, making them the main structures that bear weight during standing and movement. Short bones are cube-shaped and focus on stability and precise movement; flat bones protect organs and provide muscle attachment surfaces; sesamoid bones, like the patella, modify tendon leverage and reduce wear, rather than bearing the main load. So weight bearing primarily involves long bones.
