The skeleton of an adult human consists of bones of various shapes and sizes that all together are 206! When we are born, the human body consists of 270 bones, some of which are fused together as we grow! Thus, in an adult, there are 80 bones in the skull and torso (28 in the skull and 52 in the torso) and 126 bones in the extremities (32 × 2 in the upper extremities and 31 × 2 in the lower extremities)!
