The canal that runs through the core of each osteon (Haversian system) is the canaliculi central (Haversian) canal perforating (Sharpey's) fibers perforating (Volkmann's) canal

The central (Haversian) canal is the main passageway running vertically through each osteon, containing blood vessels and nerves that help nourish the bone and maintain its health. This intricate network ensures that all the cells within the bone receive the vital nutrients they need to thrive, keeping our skeletal framework strong and capable of supporting our everyday activities. Speaking of bones, did you know that the arrangement of osteons in compact bone is like a tree trunk? Just like tree rings, the osteons’ concentric lamellae can provide clues about a bone's growth and age. When you take a closer look at a bone under a microscope, it's like peering into a beautifully organized library, each osteon telling its own unique story about the life it has lived and the stresses it has endured. How cool is that?
