<P> The skeleton of an adult human consists of 206 bones . It is composed of 300 bones at birth, which decreases to 94 bones in the axial skeleton (29 in the skull and 52 in the torso) and 126 bones in the appendicular skeleton (32 × 2 in the upper extremities including both arms and 31 × 2 in the lower extremities including both legs). Many small and variable supernumerary bones, such as some sesamoid bones, are not included in this count . </P> <P> The bones in a human skeleton will be more as the age will be more, as multiple bones fuse, a process which typically reaches completion in the third decade of life . In addition, the bones of the skull and face are counted as separate bones, despite being fused naturally . Some reliable sesamoid bones such as the pisiform are counted, while others, such as the hallux sesamoids, are not . </P> <P> Individuals may have more or fewer bones than this owing to anatomical variations . The most common variations include sutural (wormian) bones, which are located along the sutural lines on the back of the skull, and sesamoid bones which develop within some tendons, mainly in the hands and feet . Some individuals may also have additional (i.e., supernumerary) cervical ribs or lumbar vertebrae . </P> <P> A fully grown adult features 30 bones in the spine, whereas a child can have 33 . </P>
