So if we actually take a small cross section of our bone, we basically get the following diagram. So, we have many of these osteons.

And within this her version canal, we basically have the blood vessels, lymph vessels and our nerve cells, our nerve fibers. Now, what about the connecting regions between these hiversion canals?
