Description
Peripheral area of the diaphysis (shaft) of an embryonic bone, light micrograph. The periosteum is in the upper part of the image, showing two layers: an outer, or fibrous layer (pink), and an internal, or osteogenic layer, with a more cellular mesenchyme, where the osteoprogenitor cells are generated. In the more peripheral bone trabeculae, osteoid lines appear formed by osteoblasts that are increasing the thickness the diaphyseal cortex. As can be seen in the image, the mean diameter of the trabeculae of immature bone tissue increases from the periosteum to the inside, since, once formed in the periosteum, new layers of bone matrix continue to be attached as time passes. In the internal part, resorption takes place and progressively increases the size of the medullary cavity. Magnification: x90 when printed at 10 centimetres across.
