Bones, cartilage, ligaments, and tendons make up the skeletal system.

The skeletal system gives the body its structure and shape.

The skeletal system protects vital organs like the heart and lungs.

Bones act as levers to enable movement.

Bones store minerals like calcium for the body's use.

Red bone marrow creates red blood cells, white blood cells, and platelets.

Red bone marrow produces blood cells; yellow bone marrow stores fat.

Compact bone is dense; spongy bone is less dense.

The basic structural unit of compact bone.

Bone-forming cells.

Bone-resorbing cells.

Mature bone cells.

Hyaline cartilage for bone growth.

A smooth tissue that covers ends of bones.

There are 206 bones in an adult.

There are 28 bones in the human skull

Bones that make up the spine.

Malleus, incus, and stapes (hammer, anvil, stirrup).

Bones that form the skull.

Act as shock absorbers in the spine

The arms and legs, assisting in movement.

Supports weight and protects organs

Collarbone

The shaft of a long bone.
