Studies on the Divergence of the Rami lienales at the Hillus of the Spleen in Korean Cattle

한우비장(韓牛脾臟)에 있어서 비동맥비지(脾動脈脾肢)의 분기(分岐)에 관(關)해서

This study was conducted to ramify of the Rami lienales at the hilus of the spleen in Korean cattle. The materials used were fifty spleens, 25 fresh samples, and 25 Cast specimens. The results obtained are summarized as follows. 1. The splenic arteries were divided into 2 Rami lienales (32 cases, 64%) and 3 Rami lienales(18 cases, 36%). and their branches were nominated as Aa, terminales superior et inferior and A. polares superior. 2. To ramify the A. terminalis superior and A. terminalis inferior, only one case diverged in the splenic parenchyma and 49 cases diverged in the outside of the spleen. 3. Immediately after dividing from the splenic artery to the Aa. terminales superior and inferior, the calibres of the A. terminalis inferior were larger than the A. terminalis superior (sup. 5.5 mm., inf. 8. 5mm.). 4. It was also observed, in all samples used. that Rami lienalis of the splenic artery were not anastomosis in the out side of the spleen.
