The left coronary artery entered the wall of the left ventricle, descended into the depth of the myocardium and ramiffied to supply the leftteral well of the left ventricle. The artery had no circumflex branch. The right coronary artery descended into the depth of the myocardium and supplied the lateral wall of the right ventricle. The artery had a small circumflex branch in four of 17 specimens. The greater part of the interventricular septum was supplied by a stout septal branch which arose from the right coronary artery in 10 of 17 specimens, from the left coronary artery in 6 specimens, from the right aortic sinus in one case. The atria were supplied mainly by the left and right bronchoesophageal arteries, which arose from either the subclavian or the internal thoracic arteries. The left cardiac vein, corresponding to the great cardiac vein in other mammals, was a small vein. It ascended between the pulmonary trunk and the anterior wall of the left atrium and drained into the right atrium in 5 of 11 specimsns, into the right anterior vena cana cava in 3 specimens, and into the left anterior vena cava in the other three cases. The posterior vein of left ventricle and the middle cardiac vein showed a configuration similar to that of other mammals. The anterior cardiac vein of the pulmonary conus emptied into the right atrium in 10 of 11 cases, two of which anastomosed with the left anterior vena cava. In the last case the vein drained directly into the left anterior vena cava. The small cardiac vein was not observed in all the hearts examined.}, pages = {21--31}, title = {ラットの心臓の血管分布}, volume = {35}, year = {1988} }
