5 functions of bones SSPPM | Support; Protection; Movement; Production; Storage |
What do bones store? | tissue rich in calcium phosphate; stores Mg, Na, K, Carbonate |
Yellow bone marrow stores | Triglycerides; chemical energy reserves |
5 bone classification FLISS | Flat, long, irregular, short, sesamoid |
2 types of bone tissue | Compact and spongy; spongy protects bone marrow |
How many types of bone cells? | 3 |
Osteoblasts | bone forming cells; secretes a matrix; once surrounded called osteocytes |
Osteocytes | mature bone cells that carry on cellular activity of the bone |
Osteoclasts | Cells from white blood cell; bone eating |
Ossification or Osteogenesis | process by which bones form |
Bones form by the replacement of existing connective tissue is formed in one of two ways | Intramembranous and Endochondrial |
Intramembranous ossification | develops from layers of connective tissue; simplest and direct; makes flat bones |
Endochondral ossification | develops first as hyaline cartilage and is replaced by bone tissue; all other bones formed by this |

What are the facial bones? | Lacrimal; Nasal; Vomer; Zygomatic; Inferior Nasal Conchae; Palatine; Maxilla, Mandible |
Only free floating bone? | Hyoid bone |
Synarthorsis | Immovable joint |
Flexion | bending a joint so the angle between the parts come together |
Extension | straightening the joint |
Dorsiflexion | flexing ancle |
Plantar flexion | extending the foot |
