"blood supply: iliolumbar artery, branches of femoral, obturator and deep circumflex iliac arteries"
"The iliacus muscle is mainly supplied by the iliolumbar artery - a branch of the internal iliac artery. Besides that, it also receives arterial blood supply from the branches of the femoral, obturator and deep circumflex iliac arteries."
"The muscle lies in the concavity of the iliac fossa, lateral to the psoas major muscle. There are several nerves of the lumbar plexus that pass over the anterior surface of the muscle, including (from lateral to medial):"
