Cartilage

1. It is soft elastic and flexible

2. Cells are known as chondrocytes

3. Matrix is non vascular

4. Matrix is a homogenous mass without lamellae

5. Matrix has a protein called chondrin

6. Matrix is entirely organic

7. Matrix may or may not have calcium salts

8. Each Cartilage lacks blood supply except in perichondrium

9. Growth pattern of cartilage is unidirectional

10. Chondrocytes lack protoplasmic process

11. Lacunae lack canaliculi

12. Each lacunae has 2-3 chondrocytes

13. Bone marrow like structure is absent

14. Haversian systems and Volkman’s canals are absent

15. Three types- hyaline cartilage, fibro cartilage and elastic cartilage

Bone

1. It is hard, inelastic and tough

2. Cells are known as osteocytes

3. Matrix is vascular

4. Matrix occur in lamellae

5. Matrix has a protein called ossein.

6. Matrix is both organic and inorganic

7. Matrix always have calcium salts predominantly calcium phosphates

8. Bones are rich in blood supply

9. Growth pattern of bone is bidirectional

10. osteocytes have filopodia

11. Lacunae gives off canaliculi

12. Each lacunae has only one bone cell (osteocyte)

13. Bone marrow is present ( a haematopoietic tissue from which all blood cells are formed)

14. Haversian systems and Volkman’s canals are present

15. Two types- compact bone and spongy bone

➧Types 0f Skeletal Tissue are:-▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃⤵

➊❫ Cartilage:-   ▬▬▬▬▬▬▬▬☟

◉ Its nature is film but elastic.

◉ Herversian system is absent.

◉ Blood supply is limited to perichondrium.

◉ Mineral matter is deposited only in calcified cartilage.

◉ Chondrocytes cells occurs in groups of 2 or 4.

❱ It's Functions are:-═══════════════☟

①❭ It support the whole skeleton of body.

②❭ Intervertebral disc of cartilage absorb Shock.

③❭ It also act as a cushion against stress.

④❭ It prevents wear and tear.

❷❫ Bone:-      ▬▬▬▬▬▬▬▬☟

◉ Its nature is firm & brittle.

◉ Haversian system is present.

◉ Blood is supplied to the inner region of the bone.

◉ Mineral matter is deposited in the matrix in the form of carbonate & phosphate of calcium.

◉ 0steocytes secure singly & are arranged in lamellae.

❱ It's Functions are:-═══════════════☟

①❭ It support the framework & protect internal organs.

②❭ It helps in locomotion.

③❭ It provide surface for the attachment of muscles.

④❭ It is the Reservoir of calcium & phosphorus.
