Function of the skeleton
- Support of soft tissues of body
- Mineral Reservoir (Calcium/ Phosphate)
- Energy Storage (Yellow marrow)
- Blood Cell Production (Red bone marrow)
- Protection of vital organs
- Leverage & Movement
Connective Tissue Proper (2)
- Dense Regular C.T
- Adipose

Cartilage Characteristics
- No blood vessels/ nerves
- Consists primarily of Water (60-80%)
- Surrounded by PERICHONDRIUM
- 0 Fibrocartilage
- Growth ends at 18-20
- Little Healing in adulthood
- Collagen Resists Tension
- Poor at resisting "shearing forces"
- Cartilage Cells
Cartilage Types (3)
- Hyaline
- Elastic
- Fibrous
Hyaline Cartilage
- Most abundant
- Has fibers
- Loated on end of bone (growth plate)
Elastic Cartilage
- Many elastic fibers
- Tolerates repeated bending/ recoil.
- Located within ears/ epiglottis
Fibrocartilage
- Abundant collagen fibers
- Resists twisting and compression
- NO PERICHONDRIUM
- Located in intervertebral disc, menisci.
Every bone has...
- Blood vessels
- Nerves
- Lymphatic Vessels
Spongy (Cancellous) Bone
- Form trabeculae (beams) ti resist directional stresses
- Cavities filled w red bone marrow
- Found in epiphysis & center of bone organ
- Replaced every 4 years
Compact Bone
- Bone from concentric rings of matrix
- Bone cells are trapped w/ in cavities
- Originated "nested rings" in periphery of bone
- Replaced every 10 years
