Normally, the urachus closes off to become the median umbilical ligament; however, if it remains open, urine can drain from the bladder to an opening by the umbilicus. [1] This condition is a rare defect, mostly found in children, and is also known as an open or patent urachus. [2] [3]
At birth, when the placental circulation ceases, the pelvic portion only of the umbilical artery remains patent gives rise to the superior vesical artery (or arteries) of the adult; the remainder of the vessel is converted into a solid fibrous cord, the medial umbilical ligament (otherwise known as the obliterated hypogastric artery) which ...
The medial umbilical ligament, cord of umbilical artery, or obliterated umbilical artery is a paired structure found in human anatomy. It is on the deep surface of the anterior abdominal wall , and is covered by the medial umbilical folds ( plicae umbilicales mediales ).
The bladder receives blood by the vesical arteries and drained into a network of vesical veins. [11] The superior vesical artery supplies blood to the upper part of the bladder. The lower part of the bladder is supplied by the inferior vesical artery, both of which are branches of the internal iliac arteries. [11]
The vesiculodeferential artery, also known as the middle vesical artery, is an artery that supplies blood to the seminal vesicles. Structure The ...
In the female it is divided into two branches, the lateral pubovesical ligament and the medial pubovesical ligament. The lateral branch extends from the neck of the bladder to the tendinous arch of the pelvic fascia. The medial pubovesical ligament arises from the neck of the bladder and is a forward continuation of the tendinous arch to the pubis.
The pubic symphysis is a nonsynovial amphiarthrodial joint. The width of the pubic symphysis at the front is 3–5 mm greater than its width at the back. This joint is connected by fibrocartilage and may contain a fluid-filled cavity; the center is avascular, possibly due to the nature of the compressive forces passing through this joint, which may lead to harmful vascular disease.

In human anatomy, the median umbilical ligament is an unpaired midline ligamentous structure upon the lower inner surface of the anterior abdominal wall. [1] It is covered by the median umbilical fold. [citation needed] The median umbilical ligament represents the remnant of the fetal urachus.
