Explain the structure and development of the skeletal system. The skeletal system is made up of 206 bones which protects, support and allows the human body to move. The skeletal system also consists of tissues such as; tendons, ligaments and cartilage - these components connect the bones together which results to the posture and framework of the body. The skeletal system of a new born baby consists of more bones than an adult (roughly 300 bones); this is because the bones have not been joined together by the tissues. As the human body grows, the smaller bones are joined together to form larger bones in the body. Teeth are also a part of the skeletal system - they are made of dentin and enamel. Enamel is the strongest substance in the body. The structure of the skeletal system on a whole consists of ligaments, tendons, cartilage, joints, sockets and bones which all interrelate and play a massive part in the functioning of the body by protecting the internal organs and allowing the body to maintain balance and posture. Ossification is the process whereby new bones are created and developed by cells named osteoblasts. An example of ossification is when cartilage is transferred to bone however, factors determine the transformation. Calcium and the consumption of vitamin D will allow the process of ossification to occur efficiently so that the bones can harden and the chances of fractures and breaks can be prevented. Bones are sturdy to hold a person’s body fat however, they
