Iliac

Iliac refers to anything related to the ilium, the largest bone of the pelvis. In the context of anatomy, the term 'iliac' is often used to refer to specific structures in the body that are associated with this bone.

Anatomy

The iliac region of the body includes the Iliac crest, the Iliac fossa, and the Iliac artery. These structures play crucial roles in the body's skeletal, circulatory, and muscular systems.

Iliac Crest

The Iliac crest is the superior border of the ilium. It serves as an attachment point for several muscles, including the Iliocostalis, Iliacus, and Gluteus maximus.

Iliac Fossa

The Iliac fossa is a large, smooth concavity in the internal surface of the ilium. The fossa is covered by the iliacus muscle and forms part of the floor of the pelvis.

Iliac Artery

The Iliac artery is a major blood vessel in the pelvis. It is divided into the internal and external iliac arteries. The internal iliac artery supplies blood to the pelvic organs, gluteal region, and medial compartment of the thigh. The external iliac artery continues as the femoral artery, which supplies blood to the lower limb.

Clinical Significance

Several medical conditions and procedures are associated with the iliac region. These include Iliac artery aneurysm, Iliac crest syndrome, and Iliac fossa pain. In addition, the iliac crest is often used as a site for bone grafting in various surgical procedures.
