What does the medial umbilical ligament do?

What does the medial umbilical ligament do?

The main function of the medial umbilical ligament in postnatal life is to provide support for the urinary bladder, together with the median umbilical ligament.

What becomes the median umbilical ligament?

The median umbilical ligament begins as the allantois in the embryonic period. It then becomes the urachus in the fetus. This later develops into the median umbilical ligament at birth. It is also formed from the cloaca in utero.

What is the median umbilical ligament?

A fibrous cord that connects the urinary bladder to the umbilicus (navel). The median umbilical ligament is formed as the allantoic stalk during fetal development and lasts through life. Also called urachus.

Where is the medial umbilical ligament?

The medial umbilical ligament (or 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).

What is the medial umbilical ligament a remnant of?

umbilical arteries
The medial umbilical ligaments are anatomical remnants of the obliterated foetal umbilical arteries. The folds are 2 of the 5 umbilical folds and should not be confused with the single midline median umbilical fold.

What does the median umbilical fold cover?

The median umbilical ligament is a structure in human anatomy. It is a shrivelled piece of tissue that represents the remnant of the embryonic urachus. It extends from the apex of the bladder to the umbilicus, on the deep surface of the anterior abdominal wall. It is unpaired.

What does the umbilical artery become after birth?

After birth, the proximal portions of the intra‐abdominal umbilical arteries become the internal iliac and superior vesical arteries, while the distal portions are obliterated and form the medial umbilical ligaments.
