2  Revise the names of bones  Understand the functions of bone  List the types of bone  Explain the structure of bone

3  From the skeleton diagram, label the bones indicated using the correct terminology

4  The functions of the skeleton and bone tissue are: 1. Support – provide a framework for attachment e.g. muscle to bone 2. Protection – protect the internal organs e.g. ribs protect the lungs 3. Movement – when muscles contract they pull on bones and produce movement 4. Mineral storage – bones they store calcium and phosphorous 5. Blood cell production – occurs within the red bone marrow 6. Storage of energy – yellow marrow is a stored source of lipids in the bones

6  Short Bones – often cube shaped with the same width and length e.g. wrist, ankle, fingers and toes  Long Bones – are longer than they are wide e.g. femur, phalanges and humerus  Flat Bones – provide flat area for muscle attachment e.g. scapula, ribs, sternum and skull  Irregular Bones – have no regular shape characteristics e.g. vertebra and facial bones  Sesamoid Bones – small bones developed in tendons around some joints e.g. patella (knee)

9  Bones are strong and hard, and come in many shapes.  Bones have a hard outer layer called the compact bone. This outer layer makes up about 80% of the total bone mass of an adult skeleton. This layer gives the bone its white color.  The inside of the bone is called cancellous or spongy bone. Although the cancellous tissue makes up only remaining 20% of the total bone mass, it is light and porous, and makes up most of the bone material. The cancellous tissue also has space for blood vessels and marrow.

10  Bone marrow, in the middle of long bones, produces blood cells in a process called haematopoiesis. New red and white blood cells are produced every day to maintain constant blood levels.  Cartilage- firm, rubbery tissue that cushions bones at joints. A flexible kind of cartilage makes up other parts of the body, such as the larynx and the outside parts of the ears
