List of bones of the human skeleton

An adult human skeleton is commonly quoted as consisting of 206 bones. Reports on the typical number of bones have varied historically depending on how different sources choose to count features such as fused bones (for example, the sternum). The actual number of bones in any individual skeleton varies depending on factors such as age and anatomical variation.

The list of 206 bones in the adult skeleton can be subdivided into the axial skeleton (80 bones) and the appendicular skeleton (126 bones). 172 of 206 bones are part of a pair and the remaining 34 are unpaired. Many small accessory bones, such as sesamoid bones, are not included in the standard list.
