The Three Layers of the Bone

The Three Bone Cells

Smooth and flexible substance that covers the tip of the bones where bones meet. The lubricated substance will allow bones to perform movement whilst meeting each other's tips without any dry friction

Where bones come together

Bands of strong connective tissue that hold / connect bones together

1. Supports weight and facilitates movement, longer than they are wide (e.g. femur and humerus)

2. A squat, cubed-shaped, provide stability and some movement, e.g. wrist and ankle bones

3. Flattened, broad surface, protects internal organs, e.g. ribs, pelvis, shoulder blade, skull and breast bone

4. Has a complex shape, which helps protect the organs, e.g. spine

5. Embedded in tendons, reinforces and protects tendons to stress and wear, e.g. kneecap

When there's a break in the bone due to stress, age, trauma or illness

Bone cancer

Bone loss caused by calcium deficiency, leads to fragile and brittle bones

When connective tissues such as ligaments and tendons overstretch or tear due to age, trauma or illness
