The human skeleton of an adult usually consists of around 206 bones, depending on the counting of sternum (which may alternatively be included as the manubrium, body of sternum, and the xiphoid process).^[1] It is composed of 270 bones at the time of birth,^[2] but later decreases to 206: 80 bones in the axial skeleton and 126 bones in the appendicular skeleton. 172 of 206 bones are part of a pair and the remaining 34 are unpaired.^[3] Many small accessory bones, such as sesamoid bones, are not included in this. The precise count of bones can vary among individuals because of natural anatomical variations.
