Volkmann's canals, also known as perforating canals, play a crucial role in bone anatomy by facilitating the connection of adjacent osteons, which are the fundamental structural units of compact bone, to the periosteum, the outer connective tissue layer surrounding the bone. These canals run perpendicular to the long axis of the osteons and allow for the passage of blood vessels and nerves between the osteons and the outer surface of the bone.

This connection is vital for the nourishment of bone cells and for the overall health and maintenance of the bone structure, as it ensures that the inner and outer areas of the bone are supplied with essential nutrients and signals. Therefore, the primary purpose of Volkmann's canals is indeed to connect adjacent osteons to the periosteum, facilitating communication and transport within the bone.
