1. Dense Connective Tissue Regular vs Irregular

2. Dense Irregular CT = dermis

3. Fibroblasts with collagen fibers (red) in different planes Dense Irregular CT = dermis

4. Dense Regular CT = tendon Parallel bundles of collagen (pink) with aligned fibroblasts

5. Dense Regular CT = ligament Parallel bundles of collagen (pink) with elastin fibers (ribbon candy) and non-aligned fibroblasts

6. Dense Connective Tissue Cartilage

7. Low mag of hyaline cartilage

8. High mag of hyaline cartilage – cells in lacunae in amorphous matrix

9. TEM of chondrocyte

10. Elastic cartilage – dark purple fibers in matrix

11. High mag of elastic cartilage

12. Low mag of fibrocartilage between two pieces of bone

13. High mag of fibrocartilage – aligned cells with bundles of collagen

14. Dense Connective Tissue Joints

15. Diagram of intervertebral joints

16. Intervertebral joint – NP = nucleus pulposa; AF = annulus fibrosa; A =articular cartilage

17. Diagram of a synovial joint

18. Synovial joint – C = articular cartilage; Cp = joint capsule; S = synovial membrane; E = ligament

19. Synovial joint – articular cartilage (AC) AC
