The experiments were carried out on 50 Wistar rats (Rattus norvegicus f. domestica); males and females, weighing 200—architecture of the vessels in the abdominal cavity was studied using corrosion casts prepared with Duracryl Dental and PUR SP (polyurethane material). Our observations focused on the a. mesenterica cranialis et caudalis. The a. mesenterica cranialis originated from the aorta abdominalis cranial to the a. renalis dextra, or as a common trunk with the a. renalis dextra, or after branching off of the a. renalis dextra. The a. colica media, the a. pancreaticoduodenalis caudalis, the a. colica dextra, the aa. jejunales, and the a. ileocecocolica all originated from the a. mesenterica cranialis. We observed a common origin of the a. colica media et dextra, or the a. colica dextra after the emanation of the a. colica media. The third branch was the a.pancreaticoduodenalis caudalis. The Aa. jejunales formed a jejunal arcade, or we observed the presence of a jejunal trunk. The a. mesenterica caudalis originated from: the zone of the aortic bifurcation, the aorta cranial to the branching off of the a. sacralis mediana, caudal to the a. sacralis mediana, or the vessel branched off from the a. iliaca communis dextra.
