Chondrology |
|
Composition |
Collagen fibres only |
Collagen fibres and elastic fibres |
|
Blood Supply |
Highly vascularized |
Avascular except for the outermost layer (Perichondrium) |
|
Matrix |
Solid, hard, and non-pliable |
Solid, soft, and pliable (compressible) |
| Arrangement of Matrix | Matrix is arranged in the form of concentric layers known as Lamellae. | Matrix is Homogenous |
| Lacunae | Lacunae have canaliculi and one osteocyte is present in a lacuna | Lacunae do not have canaliculi and up to 8 chondrocytes can be present in a lacuna |
|
Regeneration/ Healing Capacity |
The abundant blood supply for nourishment and healing |
Limited regenerative capacity |
| Sensation | Sensation present due to the presence of nerves | Sensation absent due to the absence of nerves |
|
Cells |
Osteoblasts, Osteocytes, Osteoclasts |
Chondroblasts, Chondrocytes, Chondroclasts |
| Location of Osteoblasts and Chondroblats | Osteoblasts are present on the inner and outer periphery. | Chondoblasts are present on the outer periphery. |
|
Matrix Components |
Organic: Ossein protein, Chondroitin-4-Sulphate, Hyaluronic acid Inorganic: Calcium salts (Calcium carbonate, Calcium phosphate, etc.) |
Organic: Chondrin protein, Chondroitin-6-Sulphate, Hyaluronic acid Inorganic: Rare deposition of minerals |
|
Function |
The skeletal framework of the body, provide structural support, protect organs, serve as muscle attachment points, and enables locomotion and movement. |
Act as a shock absorber, reducing friction in joints. |
Difference Between Bone And Cartilage
Difference Between Bone And Cartilage: Bone and Cartilage are two types of Skeletal connective tissues found in the human body. They both play crucial roles in supporting the body and protecting organs, flexibility, locomotion and movement. They both form the endoskeleton of the human body. There are several key differences between bone and cartilage in terms of structure, composition, and function. This article covers the key distinctions between these two in detail.
