The Right common iliac is somewhat longer than the left, andforms a more obtuse angle with the termination of the aorta; theangle of bifurcation is greater in the female than in the male. Relations.—The relations of the two arteries are different on thetwo sides of the body. The right common iliac is in relation in frontwith the peritoneum, and is crossed at its bifurcation by the is in relation posteriorly with the two common iliac veins, andexternally with the psoas magnus. The left is in relation in frontwith the peritoneum, and is crossed by the rectum and superiorhemorrhoidal artery, and at its bifurcation by the ureter. It is inrelation behind with the left common iliac vein, and externally withthe psoas magnus. INTERNAL ILIAC ARTERY. The Internal Iliac Artery is a short trunk, varying in length froman inch to two inches. It descends obliquely to a point opposite theupper margin of the great sacro-i
