What causes medial 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 plica Umbilicalis?
English. a fold of peritoneum on the anterior wall of the abdomen covering the urachus, which is the fibrous remains of the allantois after birth.
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 is medial umbilical fold?
The medial umbilical folds are bilateral raised ridges of parietal peritoneum in the deep aspect of the anterior abdominal wall formed by the underlying medial umbilical ligaments running from the pelvis to the umbilicus.
Where is 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.
Which ligament runs from the umbilicus?
The falciform ligament
Abdominal and Pelvic Anatomy The falciform ligament arises at the umbilicus and continues toward the anterior aspect of the liver in continuity with the umbilical fissure (Fig. 2.79).
What is inguinal fossa?
Description. The medial inguinal fossa is a depression located within the inguinal triangle on the peritoneal surface of the anterior abdominal wall between the ridges formed by the lateral umbilical fold and the medial umbilical ligament, corresponding to the superficial inguinal ring.
What is in the lateral umbilical fold?
The lateral umbilical fold overlies the inferior epigastric artery and its accompanying veins. Unlike the median and medial umbilical folds, the contents of the Lateral Umbilical fold remain functional after birth.
What forms the medial and lateral umbilical ligaments?
Unlike the median and medial umbilical folds, the contents of the lateral umbilical fold remain functional after birth. It originates just medial to the deep inguinal ring to the arcuate line on the posterior surface of the anterior abdominal wall….Lateral umbilical fold.

How many umbilical ligaments are there?
two medial umbilical folds on the occluded umbilical artery. two lateral umbilical folds on the inferior epigastric vessels.
What is the medial collateral ligament?
The medial collateral ligament (MCL) is one of four ligaments that keep the knee joint stable. The MCL spans the distance from the end of the femur (thigh bone) to the top of the tibia (shin bone) and is on the inner side of the knee joint. That’s why it’s so painful when the ligament is stretched too much or torn.
How can you tell an indirect or direct inguinal hernia?
Inguinal hernias may be direct or indirect. The difference is in the anatomical location. Direct hernias protrude through the posterior (back) wall of the inguinal canal. Indirect hernias protrude through the inguinal ring….Symptoms
- A bulge in the groin area.
- A bulge in the scrotum.
- Pain or burning in or around the groin.
Why is it called indirect inguinal hernia?
Because the sac emerges through the deep inguinal ring and passes through the inguinal canal, it is an indirect type and because it passes beside the spermatic cord we call it juxtacordal hernia. Because of the thick extraperitoneal fat layer over the sac, we think this hernia is acquired.
What is the lateral umbilical ligament?
The fibrous cord extending from the bladder to the umbilicus. It represents the obliterated internal iliac artery of the fetus.
Where is the lateral umbilical ligament?
The lateral umbilical folds are bilateral raised ridges of parietal peritoneum in the deep aspect of the anterior abdominal wall overlying the inferior epigastric vessels. The paired folds originate medial to the deep inguinal ring and end at the arcuate line on the posterior aspect of the anterior abdominal wall.
Is urachus the same as allantois?
The urachus is a fibrous remnant of the allantois, a canal that drains the urinary bladder of the fetus that joins and runs within the umbilical cord. The fibrous remnant lies in the space of Retzius, between the transverse fascia anteriorly and the peritoneum posteriorly.
