An adult human body typically has 206 bones. At birth, humans have around 270 bones, but many of these fuse together during growth to reach the adult count of 206 bones

. These 206 bones are divided into two main groups:

  • Axial skeleton : 80 bones, including the skull, spine, and chest.
  • Appendicular skeleton : 126 bones, including the arms, legs, pelvic and pectoral girdles

The exact number can vary slightly due to anatomical variations such as extra (supernumerary) bones or fused bones in some individuals

. Some small accessory bones like certain sesamoid bones may or may not be counted in the total 206. In summary, the standard adult human skeleton contains 206 bones, organized into axial and appendicular divisions, with some variation possible among individuals
