股动脉(拉丁语:arteria femoralis)来自外髂动脉,为供应下肢的主要动脉。 外髂动脉在经过腹股沟韧带深层后改名为总股动脉。之后总股动脉会分为股动脉及深股动脉,在股三角(英语:femoral triangle)中沿前内侧下行。股动脉之后会穿过内收肌管(英语:Adductor canal),并进入内收大肌(英语:Adductor magnus muscle),进入内收大肌后股动脉改名为腘动脉。
股动脉的起源处3到4公与股静脉(英语:femoral vein)伴行,包覆于股动脉鞘(英语:femoral sheath)之中。
与股动脉相关的解剖构造如下:
下列是股动脉的分支:
在临床上,股动脉未分支出股深动脉以前又常被称为“股总动脉”(Common femoral artery)而股动脉的延续分支则又被称做股浅动脉(uperficial femoral artery)。
上臂动脉(英语:Brachial artery)与股动脉作用类似。
