What is the axial skeleton?
Bones in the long axis of the body
Appendicular skeleton?
Bones attached to axial skeleton
Which 2 bones make up the upper limb girdle?
Clavicle and Scapula

Which 3 bones make up the lower limb girdle?
Illium, Ischium and pubis

What two major parts are long bones made of?
Diaphysis and Epiphysis

What structures are found in the epiphysis?
- Spongy bone
- Epiphyseal line
- Articular cartilage

Describe the structures that are found in the diaphysis
- Medullary cavity
- Nutrient foramen
- Endosteum
- Periosteum
- Marrow

What is the function of cortical bone?
- Support
- Protection
- Calcium store
Function of spongy bone?
- Bone marrow
- Haematopoeisis
Two functions of the periosteum?
- Allows bone to attach to muscle
- Allows pathway for blood vessels
Where is the metaphysis located?
Between the epiphysis and diaphysis

How does increase in width of bone occur?
- Appositional growth
How does lenthening growth of bone occur?
Interstitial growth
Which part of the diaphysis will give rise to appositional growth?
Periosteum
Where in the epiphysis will interstitial growth occur?
Epiphyseal growth plate
