維基百科,自由的 encyclopedia

內陰動脈為內髂動脈(英語:internal iliac artery)前分支的終末分支,在雌性個體身上較雄性細小。
解剖
內陰動脈源自於內髂動脈,並爬經骨盆側壁。並於坐骨大孔(英語:greater sciatic foramen)的梨形肌(英語:piriformis muscle)下方離開骨盆腔,進入臀部。之後沿着薦棘韌帶(英語:sacrospinous ligament),穿過坐骨小孔(英語:lesser sciatic foramen)進入會陰。後與內陰靜脈(英語:internal pudendal veins)及陰部神經在會陰管(英語:pudendal canal)中並行。
分支
內陰動脈擁有以下分支:
