The adult human skeleton contains 206 bones. The skeleton of an infant contains 350 (the bones fuse together as you grow). And more than half of your 206 bones are found in your hands and feet. There are 29 bones in the skull, 31 in each leg, 32 in each arm and 26 in the spine. Some bones are long and thick like your thigh bone called it as a femur bone. Other are thin, flat and wide like your shoulder blades.
