Which bones are found in the wrist, ankle, and spinal column?

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

Answer: (A)

Bone shapes are grouped into long, short, flat, and irregular. Irregular bones have complex shapes that don’t fit the other three categories. The spinal column is made of vertebrae, which are textbook irregular bones because of their distinctive, non-slab shapes. The wrist and ankle bones are short bones (carpals and tarsals). Since the question centers on the spinal column, irregular bones best match that region, making it the best answer even though the wrist and ankle bones themselves are short.
