This framework of our body is called the skeleton
We can have some idea about the shape and number of bones in some parts of our body by feeling them. One way we could know this shape better would be to look at X ray images of the human body. Sometimes when we are hurt, or have an accident, doctors use these X-ray images to find out about any possible injuries that might have happened to the bones. The X rays show the shapes of the bones in our bodies. Feel the bones in your fore arm, upper arm, lower leg and upper leg. Try to find the number of bones in each part. Similarly, feel the bones of your ankle and knee joints and compare these with the X-ray images Bend your fingers. palm and wrist is made up of several small bones called carples. the ribs are curiously bent. They join the chest bone and the backbone together to form a box. This is called the rib cage. There bare 12 ribs on each side of chest. Some important internal parts of our body lie protected inside this cage. the backbone is made up of many small bones called vertebrae. The backbone consists of 33 vertebrae. The ribcage is joined to these bones. If backbone was made up of only one long bone,
shoulder bones , This structure is made of pelvic bones. They enclose the portion of your body below the stomach. This is the part you sit on. The skull is made up of many bones joined together . It encloses and protects a very important part of body, the brain. There are some additional parts of the skeleton that are not as hard as the bones and which can be bent. These are called cartilage.
