Superior Gluteal Artery
The superior gluteal artery is the terminal branch of the posterior division of the internal iliac artery. It exits the pelvis through the greater sciatic foramen before splitting into a superficial branch and a deep branch. Structure Origin The superior gluteal artery is the largest and final branch of the internal iliac artery. It branches from the posterior division of the internal iliac artery; it represents the continuation of the posterior division. Course, relations and branches It is a short artery. It passes posterior-ward between the lumbosacral trunk and the first sacral nerve (S1). Within the pelvis, it gives branches to the iliacus, piriformis, and obturator internus muscles. Just prior to exiting the pelvic cavity, it also gives off a nutrient artery which enters the ilium. It exits the pelvis through the greater sciatic foramen superior to the piriformis muscle, then promptly divides into a superficial branch and a deep branch. Superficial branch The superfi ...
