Bone structural unit
Bone structural unit. Computer artwork of an osteon, the basic structural unit of compact bone. Compact bone is the outer layer of a bone shaft, and contains numerous osteons. Each osteon may have a blood vessel (here, an arterial capillary, red) and a nerve (yellow). The bone structure is continuously destroyed and rebuilt by bone cells. Osteoblasts (green) embed themselves on a bone surface and build new bone. Mature bone cells (osteocytes) are seen as the tangled, branching cells (brown) inside the bone tissue. Bone tissue is destroyed by osteoclasts (two seen here). One, at lower right, has been sectioned to reveal the acid (red) with which it destroys the bone

EDITORS COMMENTS
This print showcases the intricate structure of a bone, specifically highlighting the osteon - the fundamental building block of compact bone. In this computer artwork, we are granted a glimpse into the inner workings of our skeletal system. The outer layer of a bone shaft is composed of compact bone, which contains numerous osteons. Each osteon within this remarkable network may house essential components such as blood vessels and nerves. Here, an arterial capillary in vibrant red signifies the presence of a vital blood supply, while a yellow nerve represents the interconnectedness between our bones and nervous system. The dynamic nature of bone tissue is brought to life through this illustration. The continuous process of destruction and rebuilding is orchestrated by specialized cells known as osteoblasts and osteoclasts. Osteoblasts can be identified by their green hue as they diligently embed themselves on bone surfaces to construct new layers. Meanwhile, mature bone cells or osteocytes appear as tangled brown branches nestled within the dense tissue. Intriguingly, two visible osteoclasts play an important role in resorption - breaking down old or damaged areas using acidic substances depicted here in striking red hues. This visually stunning image not only offers insight into biological processes but also emphasizes the importance of maintaining healthy bones for overall well-being.
