Volkmann Canal

Structure of a bone

Volkmann's canals ( Latin Canales perforantes ) are small bone canals that can only be seen under the microscope . They run transversely to the direction of the osteons , and thus perpendicular to the bone surface.

The Volkmann channels provide a compound of longitudinally running Havers channels or the osteons in the substantia compacta of the bone. In contrast to the latter, they are not surrounded by concentric bone lamellae. The Volkmann canals contain the smallest blood vessels with fenestrated (fenestrated) endothelium .

The Volkmann canals are named after the German physiologist Alfred Wilhelm Volkmann (1801–1889).
