5.4 SKELETAL TISSUE [Hist]
| (a) Cartilage. Cells: chondroblasts, chondrocytes. Matrix
of hyaline cartilage: proteoglycan aggregates / type II collagen
(plus elastin in elastic cartilage; type I collagen in fibrocartilage). |
|
| (b) Bone. Cells: functions of osteoblasts, osteocytes,
osteoclasts. Matrix: hydroxyapatite, type I collagen. Osteoid. |
Osteogenesis imperfecta. |
| Joints: synostoses, synchondroses, syndesmoses,
diarthroses. Synovial membrane and fluid. |
|
| Structure of mature bone: lamellar structure, Haversian
systems; trabeculae; cancellous bone. |
|
| Skeletogenesis; growth of long bones (structure of the
epiphyseal plate). |
|
| Repair of fractures. |
|
| Remodelling. Appositional growth (accretion). |
