|
|
Bones that are more porous have..... |
Smaller proportion of Calcium carbonate/Phosphate More non-mineraized tissue |
|
|
Bones can also be classified by |
Degree of Porosity Low porosity= Cortical bone -less flexible -can resist stress Found in long bones High porosity= Spongy bone -more flexible -shock absorption Eg Vertebrae |
|
|

Skull |
Made up of the Calvaria and the Face Calvaria- Protects brain Frontal, Occipital, Parietal, Temporal, Sphenoid. Face- Nasal, Lacrimal, Zygomatic, Maxilla, Mandible.
|
|
|
Most fragile of the Calvaria bones |
Temporal It overlies the major blood vessel that supplies the membrane protecting the brain. If fractured or displaced it can cause Epidural Haemorrhage. |
|
|
What is Epidural Haemorrhage |

Vertebral column |
Protects spinal cord and nerves 35 in total 7 cervical (neck) 12 thoracic (chest) 5 lumbar (lower back) 1 sacrum (midline region of buttocks) Made up of 5 fused Vertebrae. 1 coccyx (tail bone) 4/5 fused Vertebrae. |
|
|
Ribs nd Sternum |
1-7= True ribs, attached to both Sternum and Vertebrae 8-10= False ribs, attached to Vertebrae directly and Sternum indirectly 11&12= Floating ribs, attached to Vertebrae only |
|
|
