2. cartilage a flexible but strong supportive connective tissue
Connective tissue-Is avascular, lack blood vessel
contains a gelatinous ground substance- chondroitin sulfate
Embedded within the ground substance collagen and elastic protein fibers

3. There are three types of cartilage:
Hyaline - most common, found in the ribs, nose, larynx, trachea. Is a precursor of bone
Fibro- is found in intervertebral discs, joint capsules, ligaments
Elastic - is found in the external ear, epiglottis and larynx

4. KNEE JOINTS

5. Hyaline cartilage
as supportive tissues in the nose, ears, trachea, larynx, and smaller respiratory tubes
Articular cartilage,
Covering the surface of bones in synovial joints
costal cartilages where ribs attach to the sternum and is the precursor to bone in embryonic skeleton

6. Protein fiber are large and dominantly collagen
appears as a very uniform, glossy type tissue with evenly dispersed chondrocytes in lacunae.
perichondrium is found around hyaline cartilage.
Look slightly like bisophilic (cytoplasm that are stained purplish blue by Heamotoxylin
the weakest among the cartilage

7. HYaLINE CARTILAGE STRUCTURE

8. perichondrium
a layer of dense irregular connective tissue that surrounds the cartilage of developing bone

9. Elastic cartilage
found in the pharyngotympanic tubes, epiglottis, and ear lobes
Has greater quantity of visible dark-staining elastic fibers embedded in ground substance.
Perichondrium is also found around elastic cartilage
the chondrocytes are found in a threadlike network of elastic fiber within the matrix

10. lacunae
lacuna is a small space containing an osteocyte in bone and chondrocyte in cartilage

11. ELASTIC CARTILAGE STRUTURE

12. fibrocartilage The strongest amongst the cartilages
has alternating layers of hyaline cartilage matrix and thick layers of dense collagen fiber
a transitional layer between hyaline cartilage and tendon or ligament
contains fine collagen fibers arranged in layered
spongy architecture with gaps between lacunae and collagen fiber

13. FIBROCARTILAGE STRUCTURE

14. Lacunae in rib

15. Articular cartilage

16. Synovial cartilage

17. Epiglottis cartilage

18. trachea

19. Larynx

20. Costal cartilage

21. pharyngotympanic

22. Invertebral discs

23. ligament

24. cilia

25. Pubic symphysis

26. thorax

27. Uses of cartilage Reduces friction Act as shock-absorbing tissues
perform the functions of bone(larynx)
Take place of the bones eg. Nose and eyelid
Expand and contract the size of thorax
Support rough artery
Act as a glue-joining the bones of the pubis [symphysis pubica

28. forms cartilaginous ligament
hold up the cilia or hairs of the eyelids
