difference between bone and cartilage
Answers
Answer:
They are both made up of cells embedded in an extracellular matrix. It is the nature of the matrix that defines the properties of these connective tissues. Cartilage is thin, avascular, flexible and resistant to compressive forces. Bone is highly vascularised, and its calcified matrix makes it very strong.
Answer:
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
