Distribution of Renal Artery within Kidney of Korean Native Goat

한국재래산양(韓國在來山羊)의 신동맥(腎動脈)의 분포상태(分布狀態)

By employing the vinylite-and neoprene latex-corrosion technique, ramification and arrangement of A. renalis were observed in fifty Korean native goats (100 kidneys). The obtained results were as follows: 1. A single renal artery, arising on each side from abdominal aorta, bifurcated into Ramus dorsalis and Ramus ventralis from which 3~6 segmental arteries originated. 2. The dorsal and ventral surfaces of the kidney were divided separately into 3~6 arterial segments by the running of the segmental artery into the parenchyma. Of them four segments were mostly frequent (in 77% of right kidney and 83% of left). 3. In 25 of all the kidneys, either dorsal or ventral surface of a kidney was supplied from interlobar or segmental arteries belong to the opposite Ramus. 4. In 3 goats, A. polaris superior was observed. 5. Generally, distribution of the renal artery of Korean native goat resembled that of the dog.
