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.
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.
It includes the superior gluteal artery and the medial and lateral circumflex femoral arteries (the former of which provides the main supply to the femur). It is formed by the deep branch of superior gluteal artery, with ascending branches of both lateral and medial circumflex femoral arteries. The inferior gluteal artery usually joins the ...
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.
In individuals who are biological females, the ovarian artery (a branch of the abdominal aorta) and uterine arteries form anastomoses. [6] Right (distal from spectator) internal iliac artery and branches, except for iliolumbar artery, umbilical artery, uterine artery/deferential artery and vaginal artery/inferior vesical artery.
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.
It runs from the sacrum (the lower transverse sacral tubercles, the inferior margins sacrum and the upper coccyx [1]) to the tuberosity of the ischium. It is a remnant of part of biceps femoris muscle. The sacrotuberous ligament is attached by its broad base to the posterior superior iliac spine, the posterior sacroiliac ligaments (with which ...
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.
