Internal Iliac Artery
The internal iliac artery, also known as the hypogastric artery, is a major blood vessel that supplies blood to the pelvis, reproductive organs, buttocks, and the medial part of the thigh. It arises from the common iliac artery at the level of the fourth lumbar vertebra and divides into several branches to supply different areas of the pelvis.
The branches of the internal iliac artery include the superior gluteal artery, inferior gluteal artery, internal pudendal artery, and obturator artery, among others. These branches play a crucial role in providing oxygen-rich blood to the pelvic organs and surrounding structures.
In addition to supplying blood, the internal iliac artery also plays a role in venous drainage by receiving blood from corresponding veins in the pelvic region. It is a vital component of the pelvic vasculature and contributes to the overall blood supply of the lower abdominal region.
Understanding the anatomy and function of the internal iliac artery is important for medical professionals, particularly during surgeries and interventions involving the pelvic region. It is essential for maintaining proper blood flow and function of the pelvic organs.
