Abstract

The ganglia of the plexus myentericus (Auerbach) have their own self-acting vascularization in the form of periganglionic capillary networks. As to the architecture and density, they are quite different from the intramuscular capillary bed. Just as the arterial trunk and arcade vessels, the terminal arterioles and sphincter capillaries running into the periganglionic cappillary network are innervated by noradrenergic axons. Together with periganglionic arteriovenous short circuits, this means favorable prerequisites for a functionally adapted blood supply of the ganglia. The specific arrangement of intramuscular vessels and the plexus Auerbach effects the maintenance of the close topographic and functional relations between both systems in all cases of changes of the shape of the intestinal wall.

摘要

肠肌丛(奥尔巴赫丛)的神经节通过神经节周围毛细血管网的形式拥有自身的自主血管化。就结构和密度而言,它们与肌内毛细血管床有很大不同。正如动脉干和弓状血管一样,进入神经节周围毛细血管网的终末小动脉和括约肌毛细血管由去甲肾上腺素能轴突支配。连同神经节周围动静脉短路,这意味着为神经节的功能适应性血液供应提供了有利前提。肌内血管和奥尔巴赫丛的特定排列在肠壁形状发生变化的所有情况下都影响着两个系统之间紧密的地形和功能关系的维持。
