What is plica Umbilicalis?
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 the medial umbilical ligament?
The median umbilical ligament (urachal remnant) is a fibrous band in the umbilical region of the abdomen that contains the urachus (embryonic communication between the allantois and cloaca). It runs in the midline, extending from the apex of the urinary bladder to the umbilical ring on the anterior abdominal wall.
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 the inguinal triangle?
The Hesselbach triangle, also called the inguinal triangle, is a region of the lower, anterior abdominal wall, or groin, that was first described by Frank Hesselbach, a German surgeon and anatomist, in 1806. It describes a potential area of weakness in the abdominal wall, through which a hernia can protrude.
What matures as the median umbilical ligament?
Development. 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.
How is urachus patent treated?
The most common surgical therapy for patent urachus is complete excision, with or without excision of the bladder dome. Low complication rates have been reported, with the most common complication being wound infection. Recently, laparoscopic excision has been described as an alternative therapeutic approach.
What is the umbilical ligament?
(MEE-dee-un um-BIH-lih-kul LIH-guh-ment) 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.
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.
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).
Where is inguinal located?
The inguinal region of the body, also known as the groin, is located on the lower portion of the anterior abdominal wall, with the thigh inferiorly, the pubic tubercle medially, and the anterior superior iliac spine (ASIS) superolaterally.
