Some aspects of the system of Haversian canals in the diaphysary compact bone in man

The general aspect of the network of Haversian canals was studied on tangential and radial sections from the diaphysary compact bone of the human long bones. The network-like aspect was much varied even in the same bone and at the same level from which the samples were obtained. No obvious differences were found between the studied bones or between the two limbs. Certain peculiarities of the canal system were noticed as regards the trajectory of canals, disposition and number of anastomoses, and the network aspect, depending on the region of the diaphysis, but especially on the depth.
