Where in the body is each type found?
5. Which cartilage has many elastin fibers?
6. What is a cartilage cell called?
7. How does fibrocartilage differ from other cartilage? 8. How does cartilage grow?
9. What gives bone flexibility?

11. Name the 3 bone cells and their function 12. What is bone’s Extracellular matrix made up of?
13. What is calcification?
14. What is ossification?
15. What is osteogenesis?
16. What is osteolysis?
17. What is the functional unit of Compact bone? 1. Structural support to the body
2. Protection of various regions of the body 3. Mineral storage, especially calcium
4. Formation of blood cells in the marrow
A. Dense Extracellular matrix
B. Avascular
C. CHONDROCYTES within spaces called LACUNAE
D. Surrounded by dense irregular fibrous connective tissue called
PERICHONDRIUM.
LACUNAE
1. Hyaline Cartilage: joints
2. Elastic Cartilage: ear
3. Fibrocartilage: vertebral discs
ELASTIC CARTILAGE
A cartilage cell is called a chondroblast
Fibrocartilage has more collagen fibers than other cartilages Appositional = (growth in diameter)
1. Increased activity of the chondroblasts
2. Extracellular matrix is added on the sides. Interstitial = (growth in length)
1. Increased activity of the chondrocytes
2. Extracellular matrix is added between the cells Collagen fibers
Minerals
Osteoblasts: lay down new bone
Osteocytes: mature bone cell; found in lacunae
Osteoclasts: break down bone; take the calcium out of the bone and put it into the blood, especially when blood calcium levels are too low. Mineral salts with lots of phosphate.
The deposit of calcium salts within a tissue. the process of laying down new bone by osteoblasts. It occurs in bone, cartilage or fibrous connective tissue. new bone growth
