VOLKMANN’S CHANNELS
Unlike cartilage, the bone is intensely vascularized. Arteries reach the outer covering of the bone (periosteum), and its branches penetrate the bone through openings of tne bone surface.
In regions of bones formed by Haversian systems, smaller blood vessels (branches of arteries and tributaries of veins) are distributed within the bones by running inside bone tunnels called Volkmann's canals.
The Volkmann's canals connect adjacent Haversian systems. Branches of vessels present in Volkmann's canals can be recognized in cross-sections of diaphyses because they are distributed radially in relation to the medullary cavity.
