Abstract
In the Trabecula septomarginalis (moderator band) of cattle, pig and pygmy goat regularly till to 6 arteries are found, which traverse from the interventricular septum to the M. papillaris magnus. At these intramural coronary arteries (diameter 100-800 microns)--without any exception--musculoelastic intimal thickenings are recognizable, which often may result in concentric luminal narrowings of a high degree. The genesis and importance of the specificities in the wall structure of the moderator band arteries are discussed in relation to the intramural coronary arteries of the ventricular wall and papillary muscle as an adaptational reaction of the vascular wall to the extraordinary stress of these small vessels.
