1. Skeletal tissues Classification and functions
Chondroid tissue cells, inter-cellular substance
Histogenesis of cartilages
Cartilages:
a) hyaline;
b) elastic;
c) fibrocartilage
5. Bony tissue cells, intercellular substance
6. Fibrous bones
7. Lamellar bones
8. Long bones

2. Skeletal tissues Chondroid tissue Bony tissue Hyaline Elastic
Fibrocartilage
Bony tissue
Fibrous bone
Lamellar bone: a) cancellous
b) compact

3. Functions 1. Supportive 2. Mechanical 3. Protective
4. Ca and P deposition
5. Water-mineral metabolism

4. Chondroid tissue
Cells + intercellular substance (chondromucoid, chondrine fibers)
1. Has no vessels
2. Intercellular components are predominant
3. Chondromucoid
70-80 % H2O
10-15 % org.
4-7 % mineral
4. Chondrine fibers
Collagen II
Elastic

5. Chondroid tissue differon
I Stem cell
II Hemistem cells
III Chondroblasts
IV Chondrocytes
Chondroclasts

6. Differon stem cell hemistem cell chondroblasts chondrocytes
