On average, how many bones are in the adult human skeleton?

• A. 210
• B. 206
• C. 196
• D. 216

Answer: (B)

The adult skeleton is counted at about 206 bones because you start life with around 270 bones, and many fuse together as you grow. This fusion mainly happens as your skull bones join along sutures and other bones consolidate, reducing the total from the birth count to a common adult total. While most people have 206 bones, small variations can occur—some individuals may have a few extra (supernumerary) bones or slight differences in fusion—yet 206 is the standard number taught for the average adult.
