How many bones are in an adult skeleton?

• A. 206
• B. 208
• C. 210
• D. 198

Answer: (A)

Adult humans typically have 206 bones in the skeleton. This standard count comes from the fact that, at birth, there are about 270 bones, and as growth proceeds, several bones fuse together or into larger units. By the time maturity is reached, the fusion of bones in areas like the skull sutures and along the vertebral column brings the total to around 206. In forensic and anatomical contexts this 206-number serves as the baseline for an average adult skeleton, though some individuals can have slight variations due to supernumerary bones or different fusion patterns.
