Iliolumbar artery

Wednesday, October 19, 2011

The iliolumbar artery is an oxygen-rich blood vessel which arises from the internal iliac artery and supplies the pelvic muscles and bones. Having turned upward and reached the medial border of the psoas major, the iliolumbar artery divides into the lumbar branch of the iliolumbar artery and the iliac branch of the iliolumbar artery.
