在生理和行为方面，Cupiennius salei是研究得最好的蜘蛛物种之一。然而，到目前为止，它的部分解剖结构只被肤浅地描述过。因此，在比较研究蜘蛛目血淋巴维管系统的过程中，我们研究了C。salei使用几种注射方法结合半薄切片和微型计算机断层扫描（MicroCT）。与其他节肢动物一样，C. salei拥有开放的循环系统。管状心脏通过许多韧带悬挂在后躯背侧。它配备了三对口，和三对心脏动脉。心脏被心包窦包围，我们首次能够描述心包内膜。在前面，心脏由前主动脉延伸，前主动脉穿过蒂并在前体内分成两个分支。从主动脉分支发出的动脉供应前体附件和中枢神经系统。食管下神经节由许多细血管供应，这些细血管从跨神经节动脉发出并形成紧密的环。毛细血管网络，即传入和传出血管之间的互连，在这里首次证明存在于chelicerates的中枢神经系统。数据进行了比较，与现有的文献中的循环系统在蜘蛛目的形态和讨论方面的呼吸系统的扩展和不同的生活方式的不同蜘蛛。(C)2012 Elsevier GmbH.

In terms of physiology and behavior, Cupiennius salei is one of the best-investigated spider species. However, parts of its anatomy have only been described superficially to date. In the course of a comparative survey of the hemolymph vascular system in Araneae we therefore investigated C. salei using several injection methods in combination with semi-thin sections and micro computer tomography (MicroCT). Like all other Arthropoda, C. salei possesses an open circulatory system. A tubular heart is suspended dorsally in the opisthosoma via a number of ligaments. It is equipped with three pairs of ostia, and three pairs of cardiac arteries. The heart is surrounded by a pericardial sinus in which we were able for the first time to describe an intra-pericardial membrane. Anteriorly, the heart is extended by an anterior aorta which runs through the pedicel and divides into two branches within the prosoma. Arteries emanating from the branches of the aorta supply the prosomal appendages and the central nervous system. The subesophageal ganglion is supplied by numerous fine vessels which emanate from the transganglionic arteries and form tight loops. A network of capillaries, i.e. interconnections between afferent and efferent vessels, is here demonstrated for the first time to exist in the central nervous system of chelicerates. Data are compared with existing literature on the morphology of the circulatory system in Araneae and discussed with regard to the extension of the respiratory system and the varying lifestyles of different spiders.
