What is superior vesical artery?

The superior vesical artery supplies the dome of the bladder, and one of its branches (in males) gives off the artery to the ductus deferens, a part of the passageway for sperm.

What gives rise to the superior vesical artery?

The superior vesical artery arises from the proximal part of the umbilical artery, which supplies the upper portion of the bladder. It begins between the origins of the obturator and umbilical arteries; however, sometimes it may have a common trunk with the superior vesical artery.

What does the inferior vesical artery supply?

Supplying the lower portion of the bladder, the inferior vesical artery is located in the pelvis. It is a branch of the anterior division of the internal iliac artery. Blood from this artery is delivered to the fundus (base) of the bladder.

Is inferior vesical artery in females?

In males, the inferior vesical artery is a pelvic branch of the anterior division of the internal iliac artery, while in females it arises from the vaginal artery. It runs deep to the peritoneum (subperitoneal) to emerge on the inferior aspect of the urinary bladder.

Do females have a superior vesical artery?

Origin and course At this point, the superior vesical artery anastomoses with the inferior vesical artery in males and with the uterine artery in females. The superior vesical artery is continued distally by the occluded part of the umbilical artery, commonly known as the medial umbilical ligament.

Where does superior gluteal artery come from?

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.

Where do superior vesical arteries branch from?

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.

Where does the inferior vesical artery go?

The inferior vesical artery branches at the fundus to give supply to the bladder fundus and trigone as well as adjacent ureters. It may give a branch named the artery to the ductus deferens, which enters the spermatic cord. The prostatic artery more commonly also arises from the inferior vesical artery.

Is the inferior vesical artery only in males?

Conclusions: The inferior vesical artery is not specific to the male sex. The contradictions found in the literature of this artery are due to the variations observed in pelvic vascularization and to the close connections between vaginal and bladder vascularisation in women.

What is superior gluteal?

The superior gluteal nerve is found in the lower pelvis and arises from the dorsal divisions of the L4, L5, and S1 nerve roots of the sacral plexus. The superior gluteal nerve is responsible for innervation of the gluteus medius, gluteus minimus, and tensor fasciae latae muscles.

What muscles 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.

What artery supplies the placenta in the mother?

Normal Structure and Function of the Placenta Deoxygenated blood leaves the fetus via the umbilical arteries and travels through the cord into the branching chorionic plate vessels.

What nerve Innervates the uterus?

Axons innervating the uterus travel in the hypogastric nerves and terminate in the thoracolumbar spinal cord segments (T10–L2). The region surrounding the cervix represents a transitional zone and is innervated by fibers that travel in both nerves.

What does superior gluteal nerve do?

The superior gluteal nerve is responsible for innervation of the gluteus medius, gluteus minimus, and tensor fasciae latae muscles. The nerve exits the pelvis through the greater sciatic foramen superior to the piriformis muscle and accompanies the superior gluteal artery and vein.

Where is superior gluteal artery located?

pelvis
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 happens when the superior gluteal nerve is damage?

[1] Damage to the superior gluteal nerve results in paralysis of the gluteus medius muscle resulting in a characteristic gait on walking and standing known as the Trendelenburg gait.

What happens if the superior gluteal nerve is injured?

Injury to the superior gluteal nerve results in characteristic motor loss that manifests as a disabling gluteus medius limp more commonly known as a Trendelenburg or gluteal gait. Weakness of the gluteus medius muscle shifts the center of gravity to the non-affected limb producing the gait.

What is the function of the superior vesical artery?

It supplies the ureter, urinary bladder, ductus deferens and seminal gland. The superior vesical artery mainly provides small, visceral branches to the surrounding organs. In males, however, it also gives off the artery to ductus deferens.

What is the difference between the superior vesical and vesiculo-prostatic arteries?

The superior vesical artery is a branch of the umbilical artery. The vesiculo-prostatic artery usually arises from the superior vesical artery in men. The first part of the superior vesical artery represents the terminal section of the previous portion of the umbilical artery ( fetal hypogastric artery ).

What are the two most prominent arteries in the human body?

The two most prominent are the superior vesical artery and the inferior vesical artery. The superior vesical artery comes off of the internal iliac artery and sometimes the umbilical artery.

What are the different types of bladder arteries?

…bladder is derived from the superior, middle, and inferior vesical (bladder) arteries. The superior vesical artery supplies the dome of the bladder, and one of its branches (in males) gives off the artery to the ductus deferens, a part of the passageway for sperm. The middle vesical artery supplies the…
