| 21. | Direct effects of chronic alcoholism are apparent in osteoblasts, osteoclasts and osteocytes.
|
| 22. | Second, mesenchymal cells differentiate into osteoblasts or fibroblasts.
|
| 23. | This is the layer of tissue where osteoblasts reside.
|
| 24. | They also promote the growth of osteoblast cells to facilitate bone growth in infants.
|
| 25. | Bone continuously undergoes remodeling by actions of bone resorbing osteoclasts and bone forming osteoblasts.
|
| 26. | New bone is then formed by the osteoblasts.
|
| 27. | In order to mineralise the bone, the osteoblasts secrete vesicles containing alkaline phosphatase.
|
| 28. | Osteoblasts buried in the matrix are called osteocytes.
|
| 29. | When osteoblasts become trapped in the matrix that they secrete, they become osteocytes.
|
| 30. | First, the osteoblast puts up collagen fibers.
