Appendicitis symptoms and diagnosis
阑尾炎的症状和诊断
Arterial Supply
阑尾的动脉血供
The appendix is supplied by a single appendicular artery, a branch of inferior division of ileocolic artery.
阑尾由一条阑尾动脉供血，而阑尾动脉是回结肠动脉下支的一个分支。
It passes behind the terminal part of the ileum to enter the mesoappendix, and runs in its free margin to reach the tip of appendix, which is the least vascular part.
它经回肠末端的后方进入阑尾系膜，沿其游离缘至阑尾尖端--血管最少的部分。
The appendicular artery is an end artery. When the mesoappendix is short, the appendicular artery rests directly on the appendicular wall near the tip of the appendix.
阑尾动脉是终末动脉。当阑尾系膜较短时，阑尾动脉直接紧贴阑尾尖端附近的阑尾壁。
In appendicitis, this part of the artery is affected and thrombosed, leading to gangrenous change in the tip, which may perforate.
阑尾炎发生时，阑尾动脉的这一部分受到感染，并形成血栓，导致阑尾尖端发生坏疽性改变，可能引起穿孔。
Venous drainage
阑尾的静脉血供
The vein corresponds to the artery and drains into the superior mesenteric vein, which in turn drains into the portal vein.
静脉与动脉相对应，流入肠系膜上静脉，而肠系膜上静脉又汇入肝门静脉。
Lymphatic drainage
淋巴引流
The lymph vessels of the appendix drain into ileocolic lymph nodes directly or through appendicular nodes in the mesoappendix.
阑尾的淋巴管直接或通过阑尾系膜内部的阑尾淋巴结引流至回结肠淋巴结。
Nerve supply
阑尾的神经支配
The sympathetic nerve supply, which carries the pain sensations from the appendix, is derived from the T10 spinal segment via lesser splanchnic nerve and superior mesenteric plexus. For this reason, the pain of appendicitis is referred to the umbilical region.
交感神经负责传递阑尾相关的疼痛感，它经内脏小神经和肠系膜上神经丛传入，传入的脊髓是 T10 节段。因此，阑尾炎可以引起脐区疼痛。
The parasympathetic nerve supply is derived from both vagus nerves.
阑尾的副交感神经支配来自两条迷走神经。
