Bones usually have no problem supporting your body as you go about your daily activities, including exercise and play. They are strong and flexible enough to absorb the light impact your body experiences during these activities. Once in a while, a bone is put under more stress than it can handle. When that happens, it breaks. A broken bone is called a fracture by doctors. Bones can break for different reasons and in different ways.

A common stress fracture happens in the legs and feet of runners and athletes.

Learning Objectives By the end of this section, you will be able to: Define bone, cartilage, and the skeletal systemList and describe the functions of the skeletal system Bone, or osseous tissue, is a hard, dense connective tissue that forms most of the adult skeleton, the support structure of the body.
In the areas of the skeleton where bones move (for example, the ribcage and joints), cartilage, a semi-rigid form of connective tissue, provides flexibility and smooth surfaces for movement. Parts, Functions, Diagram, & Facts. Human skeleton, the internal skeleton that serves as a framework for the body.
This framework consists of many individual bones and cartilages. There also are bands of fibrous connective tissue—the ligaments and the tendons—in intimate relationship with the parts of the skeleton. This article is concerned primarily with the gross structure and the function of the skeleton of the normal human adult. The human skeleton, like that of other vertebrates, consists of two principal subdivisions, each with origins distinct from the others and each presenting certain individual features. These are (1) the axial, comprising the vertebral column—the spine—and much of the skull, and (2) the appendicular, to which the pelvic (hip) and pectoral (shoulder) girdles and the bones and cartilages of the limbs belong.
