The adult human body typically has 206 bones. At birth, humans have about 270 bones, but many of these fuse together during growth, resulting in the standard adult count of 206 bones
. These 206 bones are divided into two main groups:
- Axial skeleton: 80 bones, including the skull, spine (vertebrae), and chest (ribs and sternum).
- Appendicular skeleton: 126 bones, including the limbs (arms and legs) and the pelvic and pectoral girdles
The exact number can vary slightly due to anatomical variations such as extra (supernumerary) bones, sesamoid bones, or variations in the sternum count. Some small accessory bones are not always included in the count
. In summary, the standard adult human skeleton has 206 bones.
