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 epithelial tissues. Make sure you look at the microscopes in lab and the diagrams in this presentation.

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

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

7. Loose Connective Tissue: Adipose Tissue

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

9. Dense Regular Connective Tissue Ligaments & Tendons –

11. Dense Connective Tissue: Dense Regular CT Find: collagen fibers, nuclei of fibroblasts

12. Dense Irregular Connective Tissue Skin Dermis

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

15. Supportive Conective Tissue: Hyaline Cartilage (Smooth and Clean Matrix!) CHONDROCYTE LACUNA

17. Supportive Connective Tissue: Elastic Cartilage (Dirty Matrix!) CHONDROCYTE LACUNA ELASTIC FIBERS IN MATRIX

19. Supportive Connective Tissue: Fibrocartilage or Fibrous Cartilage (Matrix looks like water, lacuna with chondrocytes look like boats) CHONDROCYTE LACUNA

21. Practice with Connective Tissues!

22. Name this tissue

23. Dense Regular Connective Tissue Where in the body can you find this?

24. Name this tissue.

25. Dense Irregular Connective Tissue Where in the body can you find this tissue?

26. Name this tissue

27. Elastic cartilage What is the name of the “holes”? What are the names of the cells found inside these holes?

28. Name this tissue.

29. Fibrocartilage or Fibrous Cartilage Where in the body can you find this tissue?

30. Name this tissue.

31. Areolar Tissue

32. Name this tissue

33. Adipose Tissue Where is the nucleus of the adipocytes? What is filling most of the inside of the adipocyte? Where in the body can you find this tissue?

34. Name this tissue.

35. Hyaline Cartilage Where in the body can you find this tissue?
