    Abstract:
    The coronary arterial epicardial network in the monkey Macaca fascicularis was studied. The study concerned 11 hearts of healthy and fertile animals of both sexes. The morphological and morphometric results of the studies performed by microdissection revealed that: In all examined cases of the Macaca fascicularis the heart was supplied by blood through the left and right coronary arteries. The left coronary artery had a larger external diameter (1.2 mm-2.5 mm, average 1.8 mm) than the right one (0.7 mm-1.2 mm, average 0.9 mm). The left coronary artery, with the average length of 4.3 mm (1.8 mm-6.5 mm), usually (82%) ended by bifurcation in to the anterior interventricular and the circumflex branch, and less frequently (18%) by trifurcation forming, in this way, another branch: the left marginal branch. The anterior interventricular branch had the larger external diameter (0.9 mm-1.7 mm, average 1.3 mm) than the circumflex one (0.7 mm-1.7 mm, average 1.1 mm). Most frequently (73%) it could be traced along the diaphragmatic cardiac surface. The circumflex branch usually (73%) terminated as the posterior interventricular branch, and less frequently (9%) as one of the right posterior ventricular branches. The long type of the right coronary artery was observed in 45% of the cases. The presence of the myocardial bridges over the branches of the left coronary artery was found in 54% of the examined hearts. The great resemblance between the Macaca fascicularis subepicardial network with the corresponding one in humans suggest that Macacus fascicularis is a suitable experimental animal for functional studies of the cardiovascular system.
