<P> The exact arrangement of branches of the internal iliac artery is variable . Generally, the artery divides into an anterior division and a posterior division, with the posterior division giving rise to the superior gluteal, iliolumbar, and lateral sacral arteries . The rest usually arise from the anterior division . </P> <P> The following are the branches of internal iliac artery .
