The skeleton comprises of many hard and soft tissues. Hard tissues are the various kinds of bones that are present in the body. Soft tissues are the cartilages, marrow and the tendons that connect the various bones. Bones are the structures of the skeleton that provide a framework to protect the organs and give strength to the body. The cranium bone that is present in our head protects the brain and gives a rigid shape to our head. This rigid shape also makes it possible to hold the eyes, ears and nose in the right places.
