It frequently arises in common with the middle rectal artery, and is distributed to the fundus of the bladder. In males, it also supplies the prostate and the seminal vesicles.Where does the superior vesical artery come from?
The superior vesical artery originates in the pelvis, from the anterior division of the internal iliac artery. It travels along the pelvic sidewall, then courses medially toward the upper portion of the bladder within a fold of peritoneum.
Do females have superior vesical artery?
The superior vesical artery arises as the first branch of the anterior division of internal iliac artery, inferior to the pelvic brim and on the lateral wall of the lesser pelvis. … At this point, the superior vesical artery anastomoses with the inferior vesical artery in males and with the uterine artery in females.
What does the obturator artery supply?
The main function of the obturator artery is to supply the muscles of the pelvis and the adductors of the thigh; obturator externus, adductor magnus, adductor minimus, adductor longus, adductor brevis, pectineus and gracilis muscles. Additionally, it provides a branch that supplies the head of the femur.
What is vesical venous plexus?
Anatomical terminology. The vesical plexus envelops the lower part of the bladder and the base of the prostate and communicates with the pudendal and prostatic plexuses. It is drained, by means of several vesical veins, into the internal iliac veins.Where is the superior gluteal artery?
The superior gluteal artery is an artery of the pelvis. It arises directly from the posterior trunk of the internal iliac artery as its largest branch. Along its course, it supplies muscles of the posterior pelvic region. The superior gluteal artery gives off two terminal branches; superficial and deep.
What passes inferior to uterine artery?Structure. The uterine artery usually arises from the anterior division of the internal iliac artery. It travels to the uterus, crossing the ureter anteriorly, to the uterus by traveling in the cardinal ligament.

What does the inferior gluteal artery supply?
The inferior Gluteal Artery supplies: The following muscles: piriformis, ischiococcygeus, iliococcygeus, gluteus maximus, obturator maximus, obturator internus, superior gemelli, inferior gemelli, quadratus femoris muscle; The sciatic nerve. The head of the femur and upper thigh.
What does the superior gluteal artery supply?
In the gluteal region, the superior gluteal artery supplies the gluteus maximus and overlying skin, gluteus medius, gluteus minimus, tensor fascia lata. It contributes to anastomoses at the anterior superior iliac spine and the hip joint.
Where does the obturator artery come from?
The most common source of origin of the obturator artery is as a single branch arising from the anterior division of the internal iliac artery.
What artery supplies the uterus?
The ovarian artery is a direct branch of the abdominal aorta. The ovarian artery supplies oxygenated blood to the ovary, fallopian tube, and uterus. In the myometrium, the uterine artery further branches out to the arcuate artery, radial artery, spiral artery, and basal artery.
What does the femoral artery supply?
The femoral artery is a continuation of the external iliac artery and constitutes the major blood supply to the lower limb. … The femoral artery and its branches supply most of the thigh as well as the entirety of the leg and foot.
Which artery gives rise to the obturator artery?
The obturator artery (OA) is usually a branch of the anterior division of the internal iliac artery (IIA), running medially to the lateral wall of the pelvis to reach the obturator canal.
What is the purpose of the obturator?
The obturator is used to insert a tracheostomy tube. It fits inside the tube to provide a smooth surface that guides the tracheostomy tube when it is being inserted.
Which artery supplies the superior portion of the bladder in females?
Blood Supply and Lymphatics The superior and inferior vesicle arteries provide the blood supply to the bladder. These are indirect branches of the internal iliac arteries. The bladder also receives some of its blood supply from the obturator artery and the inferior gluteal artery.
What does the superior and inferior gluteal artery supply?
Branches and supply The muscular branches that arise in the gluteal region supply the gluteus maximus, obturator internus, superior gemellus, inferior gemellus and quadratus femoris muscles. These branches also supply the upper part of the hamstring muscles.
What is the blood supply of the gluteal region?
The major arteries that supply the gluteal region are the superior gluteal artery and the inferior gluteal artery. Both of these arteries bifurcate via the internal iliac arteries.
Does superior gluteal nerve supply hip joint?
The superior gluteal nerve arises from contributions from the L4- S1 nerve roots. This nerve exits the pelvis through the sciatic notch above the piriformis muscles. It supplies the gluteus medius and minimus muscles, fascia lata, and the hip joint.
What does the right superior vesical vein drain into?

What is the function of venous circulation?
The peripheral venous system functions both as a reservoir to hold extra blood and as a conduit to return blood from the periphery to the heart and lungs.
Where is the vesical plexus?
The vesical plexus envelops the lower part of the bladder and the base of the prostate and communicates with the pudendal and prostatic plexuses. It is drained, by means of several vesical veins, into the internal iliac veins.
What artery supplies the inferior heart?
The marginal branch of the right coronary artery provides blood supply to the lateral portion of the right ventricle. The posterior descending artery branch supplies blood to the inferior aspect of the heart.
What does the internal artery supply?
The internal iliac arteries (IIA) supply the majority of the pelvis and the structures within, and the external iliac artery continues down to supply the lower extremities. The arteries within the pelvis can have numerous variations and these become important during surgery within the pelvis.
What does the sigmoid artery supply?
The sigmoid arteries supply the descending colon and the sigmoid colon. There are typically 2-4 branches, with the uppermost branch termed the superior sigmoid artery. They run inferiorly, obliquely and to the left, crossing over the psoas major, left ureter and left internal spermatic vessels.
What does the caudal gluteal artery supply?
The caudal gluteal a. supplies the superficial gluteal muscle and the proximal ‘hamstring muscles’. The iliolumbar a. is the first branch of the caudal gluteal and supplies the psoas minor, iliopsoas, sartorius, tensor fasciae latae and the middle gluteal muscles.
