Long bones are found in the wrist and ankle regions. True or False?

• A. True
• B. False
• C. Often
• D. Rarely

Answer: (B)

The concept here is bone shape classification. Long bones have a stretched, lever-like form with a shaft (diaphysis) and two expanded ends (epiphyses), like the humerus, radius, ulna, femur, tibia, and fibula. The bones that make up the wrist and ankle are short bones—carpals in the wrist and tarsals in the ankle—typically cube-shaped with a mostly cancellous interior for stability and smooth gliding joints. So, while the forearm and lower leg include long bones that extend toward the wrist or ankle, the actual bones in the wrist and ankle joints themselves are not long bones. The statement is therefore false.
