Origin, Traject and Distribution of Renal Arteries (Arteriae renalis) in Chinchilla lanigera

For the present study a number of 5 female chinchilla carcasses were used. The animals were slaughtered for commercial purpuses (fur). The anatomical dissection started with the identification of the aorta (Aorta abdominalis). The next step was the intra-arterial injection of a colouring substance. The carcasses was fixed in the formaldehyde solution and subsequently the renal arteries were dissected. The first renal artery was the right renal artery (Arteria renalis dextra) and, at 0,5 cm caudally, the left renal artery (Arteria renalis sinister) arose . The origin of those arteries were disposed on the lateral part of the abdominal aorta.The origin, traject and distribution of renal arteries on the studied species have a high degree of similarity with the literature dates described for leporids.
