Revise the names of bones
Understand the functions of bone
List the types of bone
Explain the structure of bone

From the skeleton diagram, label the bones
indicated using the correct terminology
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

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)

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.

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
