1. Lab Exercise 5 Classification of Tissues: Connective Tissue
Connective Tissue: a tissue that supports, transports, binds, and protects structures in the body

2. Types of Connective Tissue

3. I will use BOTH microscopes AND diagrams to test you on connective tissues. Make sure you look at the microscopes in lab and the diagrams in this presentation and in class.

4. Make sure you know all the pieces of information listed in your notes organizer. Also know the locations of ALL tissues!

5. Bone
Description: Hard matrix made of collagen fibers and calcium salts, Bone cells (osteocytes) found in lacunae
Function: Protection and support
bone, x.s., which is a specialized form of connective tissue in which the extracellular components are mineralized, producing a hard, relatively rigid matrix. The matrix contains numerous collagen fibers which are impregnated with calcium carbonate and calcium phosphate salts.

6. Bone Haversian systems run lengthwise through the bone
Each Haversian system is nearly a round area, the central core is called the Haversian canal.
Blood vessels, lymph vessels, and nerves that supply the tissue run through the Haversian canal.
Around the canal is the matrix, laid down in concentric layers called lamellae.
The lamellae have small holes (lacunae) where the bone cells are located.

7. Bone
Find: Haversian Canal, Nuclei of Osteocyte in lacunae and Lamellae

8. Cartilage: Hyaline

9. Cartilage: Hyaline
Find: Lacuna, Chondrocyte

10. Cartilage: Elastic

11. Cartilage: Elastic
Find: Lacuna, Chondrocyte, Elastic Fibers

12. Cartilage: Fibrocartilage/ Fibrous Cartilage

13. Cartilage: Fibrocartilage
Find: Lacuna, Chondrocyte, Collagen Fibers

14. Dense Connective: Regular

15. Dense Regular Connective Tissue Ligaments & Tendons –

16. Dense Connective Tissue: Dense Regular CT Find: Collagen fibers, Nuclei of fibroblasts

18. Connective Tissue: Dense Irregular (Skin Dermis)

19. Connective Tissue: Dense Irregular
RD: dense irregular connective tissue, is important in giving the skin it overall strength and elasticity, as well as housing other important epithelial derived structures such as glands and hair follicles.
PD: loose connective tissue

20. Dense Connective Tissue: Dense Irregular CT Find: collagen fibers, nuclei of fibroblasts

21. Loose Connective: Areolar Tissue

22. Loose Connective Tissue: Areolar Tissue Find: matrix/ground substance, collagen fibers, elastic fibers, nuclei of cells

23. Loose Connective Tissue: Adipose Tissue

24. Loose Connective Tissue: Adipose Tissue Find: adipocyte, lipid droplet, nucleus of an adipocyte

25. Loose Connective: Reticular Tissue
Description: Delicate reticular fibers w reticular cells
Function: Forms internal framework supporting blood cells
Location: Lymphoid Organs

26. Loose Connective: Reticular
Find: Reticular Fibers, Blood cells

27. Blood (Vascular Tissue)
Description: fluid matrix (blood plasma), fibers only seen during clotting, cells suspended in matrix
Function: Transportation

28. Blood
Find: Red Blood Cell, White Blood Cell
