The inferior gluteal artery (sciatic artery) is a terminal branch of the anterior trunk of the internal iliac artery. It exits the pelvis through the greater sciatic foramen . It is distributed chiefly to the buttock and the back of the thigh.
Inferior gluteal artery [2]-greater sciatic foramen (inferior to piriformis muscle) and gluteus maximus muscle [2] Posterior Parietal: Iliolumbar artery [2] lumbar and iliac branches: psoas major muscle, quadratus lumborum muscle, iliacus muscle [citation needed] Lateral sacral artery [2] superior and inferior branches: anterior sacral foramina ...
The inferior gluteal nerve leaves the pelvis through the greater sciatic foramen, passing inferior to the piriformis muscle. [5] It then divides into muscular branches to supply the gluteus maximus that pass posteriorly into the deep surface of the gluteus maximus muscle. [6] The inferior gluteal nerve is superficial to the sciatic nerve.
The notch holds the piriformis, the superior gluteal vein and artery, and the superior gluteal nerve; the inferior gluteal vein and artery and the inferior gluteal nerve; the sciatic and posterior femoral cutaneous nerves; the internal pudendal artery and veins, and the nerves to the internal obturator and quadratus femoris muscles.
The cruciate anastomosis is a circulatory anastomosis in the upper thigh [1] formed by the inferior gluteal artery, the lateral and medial circumflex femoral arteries, the first perforating artery of the deep femoral artery, [2] [1] and the anastomotic branch of the posterior branch of the obturator artery.
The inferior gluteal veins are venae comitantes of the inferior gluteal artery. They commence in the superior/proximal posterior thigh. They enter the pelvis through the lower part of the greater sciatic foramen. They converge to form a single vessel before emptying into the distal portion of the internal iliac vein. [1]
The accompanying artery of ischiadic nerve is a long, slender artery in the thigh. It branches of the inferior gluteal artery. It accompanies the sciatic nerve for a short distance. [1] It then penetrates it, and runs in its substance to the lower part of the thigh.
The superficial branch passes over the piriformis muscle. [2] It enters the deep surface of the gluteus maximus muscle, and divides into numerous branches. [2] Some branches supply the muscle and anastomose with the inferior gluteal artery, while others perforate its tendinous origin, and supply the integument covering the posterior surface of the sacrum, anastomosing with the posterior ...
