Carpals are best described as which bone category?

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

Answer: (A)

Carpals are best described as short bones because they are roughly cube-shaped with dimensions that are similar in length and width. This compact, block-like structure is ideal for forming the wrist joint, providing stability and a basis for multiple small, gliding movements rather than long levers. Short bones like carpals are made mainly of spongy (cancellous) bone covered by a thin layer of compact bone, which helps absorb impact and support the many directions the wrist moves in. They aren’t long bones, which have a shaft and are designed for leverage, nor flat bones, which are thin and protect organs, or irregular bones, which have complex shapes. The wrist’s carpals therefore fit the short-bone pattern: small, cube-like, and built for stability and precise, multi-directional movement.
