The human skeletal system consists of bones and cartilages of various types. Bones and cartilages are supporting connective tissues. They provide support, surface for the attachment of muscles and protection to many vital organs like brain, heart, eyes etc. and also give a definite form and shape of the body. Moreover the skeleton plays a vital role in locomotion and movements.
Difference between Bone and Cartilage | Bone vs Cartilage

Cartilage

1. It is soft elastic and flexible

2. Cells are known as chondrocytes

hyaline cartilage
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 osteocytesTypes of bone cells
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

Compact bone tissue
Extra Points:
  • Longest bone is femur
  • Smallest bone is stapes
  • Study of body movements-Kinesiology
