All about Skeleton
Human skeleton includes 206 bones, 32 teeth other structures that connect these bones together. Each of them plays an important part in helping your body to function properly. The skeletal system has six major functions including producing blood cells, protecting organs, helping to move, storing ions and endocrine regulation. Humans have total 300 bones at the time of birth but some bones fuse together and the overall number reduces to 206. The longest bone in the body is femur or thigh bone and the smallest bone is the staples which is located in the middle ear.
