| 31. | The osteoblast then deposits calcium phosphate which is hardened by hydroxide and bicarbonate ions.
|
| 32. | Ethanol suppresses the activity and differentiation of osteoblasts.
|
| 33. | During STS-80 osteoblast cultures were grown in microgravity, using specialized hardware.
|
| 34. | Normally, bone removed by osteoclasts is replaced quickly by other cells, the osteoblasts.
|
| 35. | Osteoblasts then attach themselves to the material and form new bone as the material dissolves.
|
| 36. | Osteocytes remain alive and are connected by cell processes to a surface layer of osteoblasts.
|
| 37. | Osteoblasts do not have calcitonin receptors and are therefore not directly affected by calcitonin levels.
|
| 38. | Osteoblasts deposit a collagen matrix and release minerals that combine to make the bone mineral.
|
| 39. | Osteoblasts also group to form new bone.
|
| 40. | "' Lining cells "'come from osteoblasts which have become flattened.
