Bones, muscles, joints.

From our head to our toes, our bones provide support for our bodies and help form our shape. The skull protects the brain and forms the shape of our face. The spinal cord is protected by the backbone, or spinal column. The ribs form a cage that shelters the heart, lungs, liver, and spleen, and the pelvis helps protect the bladder, intestines, and in women, the reproductive organs.

Joints occur where two bones meet. They make the skeleton flexible - without them, movement would be impossible. Muscles are also necessary for movement: they are the masses of tough, elastic tissue that pull our bones when we move. Together, our bones, muscles, and joints - along with tendons, ligaments, and cartilage - form our musculoskeletal systems and enable us to do everyday physical activities.

The human skeleton has 206 bones. Our bones begin to develop before birth. Bone building continues throughout your life, as your body constantly renews and reshapes the bones' living tissue. Bones are made up of calcium, phosphorus, sodium, and other minerals, as well as the protein collagen. Bones are made up of two types of material - compact bone and cancellous bone. Compact bone is the solid, hard, outside part of the bone. It looks like ivory and is extremely strong. Cancellous bone, which looks like a sponge, is inside the compact bone. It is made up of a mesh-like network of tiny pieces of bone called trabeculae. Bones are fastened to other bones by long, fibrous straps called ligaments. Cartilage, a flexible, rubbery substance in our joints, supports bones and protects them where they rub against each other.

The human body has more than 650 muscles, which make up half of a person's body weight. They are connected to bones by tough, cord-like tissues called tendons, which allow the muscles to pull on bones. Humans have three different kinds of muscle: skeletal, smooth and cardiac.

Joints allow our bodies to move in many ways. Joints are classified by their range of movement. Immovable, or fibrous, joints don't move.

Partially movable, or cartilaginous, joints move a little. They are linked by cartilage, as in the spine. Freely movable, or synovial, joints move in many directions. The main joints of the body - found at the hip, shoulders, elbows, knees, wrists, and ankles - are freely movable.
