The Human Skeletal System The human skeletal system is a framework of bones which gives shape to the body. It is made of bones and the cartilage. The main bones are the ribs, backbone, skull, shoulder bones and the pelvic bones. The rib cage is a bony cage that protects the delicate organs like lungs and heart. It has many bones which are attached to the sternum. The backbone starts from the neck at the back of your body. It is made of many smaller bones and is connected to the rib cage. The skull is composed of many bones joined together and protects the most important organ of our body, the brain. The bones at shoulder are the shoulder bones while the portion on which we sit is the pelvic bone. Cartilage A tough, elastic, fibrous connective tissue found in various parts of the body, such as the joints, outer ear, and larynx. It is not as hard as bone and also can bend. Joints The Skeletal System It is a point of articulation between two or more bones, especially such a connection that allows motion. We can move our body only at places where bones meet or at joints. Activity Place a scale length-wise on your arm so that your elbow is in the centre. Ask your friend to tie the scale and your arm together. Now, try to bend your elbow. Are you able to do it? Now remove the scale and bend you hand. We are able to bend or rotate our body in places where two parts of our bones are joined.
