CELLS OF THE BONE TISSUE – 2
Some features of the bone tissue
The bone has a very particular organization of its cells, as will be seen in this and in the next pages.
– Extracellular matrix of the bone: pink after eosin staining and highlighted in light blue after hovering the cursor or clicking on the image.
– Osteocyte: seen within a small cavity of the bone matrix. These cavities are called lacunae (singular: lacuna). The osteocyte and its lacuna are highlighted in dark blue.
– Osteoblasts :present on the surface of the trabecula, highlighted in orange.
The lower image shows osteocytes within the trabecula (highlighted in blue), surrounded by bone matrix highlighted in light blue;
Observe the surface of the bone (highlighted in orange).
In both images can be seen cuboidal osteoblasts and flattened osteoblasts. The former are probably actively secreting organic bone matrix, while the flattened osteoblasts may be inactive.
