The splenic artery of four mammals--pig, greyhound, rhesus macaque, and olive baboon--was studied to determine its tortuosity and pattern of convolutions. The results were compared to those previously gathered in humans. It was found that the isolated cadaveric arteries showed a noticeable species variation in mean index of tortuosity. In the pig and dog, the artery was nearly straight throughout its length, with a very low index of tortuosity, not significantly different in the two species (P > 0.1). The artery was significantly more tortuous in the rhesus macaque and baboon than in both pig and dog, (Ps < 0.001), with a single large convolution present in the proximal one-third. In humans, the artery is commonly tortuous throughout its length and is significantly more tortuous than in the pig and dog (P < 0.001), but not significantly more tortuous than in the baboon (P > 0.1) and only just significantly more so than in the rhesus macaque (0.02 < P < 0.05). The speculation that the tortuosity of the artery may be related to habitual posture, being less in the pronograde pig and dog than in the partly orthograde rhesus macaque and baboon, is not supported by results in the wholly orthograde human.
对猪、灵缇犬、恒河猴和东非狒狒这四种哺乳动物的脾动脉进行了研究，以确定其曲折度和盘绕模式。将结果与之前在人类身上收集的结果进行了比较。研究发现，分离出的尸体动脉在平均曲折度指数上存在明显的物种差异。在猪和狗身上，动脉在其整个长度上几乎是直的，曲折度指数非常低，这两个物种之间没有显著差异（P>0.1）。恒河猴和狒狒的动脉比猪和狗的动脉明显更曲折（P<0.001），在近端三分之一处有一个大的盘绕。在人类中，动脉在其整个长度上通常是曲折的，并且比猪和狗的动脉明显更曲折（P<0.001），但不比狒狒的动脉明显更曲折（P>0.1），仅比恒河猴的动脉略显著更曲折（0.02<P<0.05）。动脉的曲折度可能与习惯性姿势有关，前肢前伸的猪和狗比部分直立的恒河猴和狒狒的曲折度小，这种推测并未得到完全直立的人类的研究结果的支持。
