The adult human body typically has 206 bones. This number results from the fusion of approximately 270 bones present at birth as a person matures into adulthood
. The skeleton is divided into two main parts: the axial skeleton, which includes 80 bones (such as the skull, spine, and ribs), and the appendicular skeleton, which consists of 126 bones (including the limbs and girdles)
. The exact count can vary slightly among individuals due to anatomical differences, such as extra ribs or sesamoid bones. Some bones, like those in the skull and certain small accessory bones, may be counted differently depending on the method used
. However, 206 bones is the standard accepted number for an adult human skeleton
