The umbilical ring is a dense fibrous ring surrounding the umbilicus at birth. [1] At about the sixth week of embryological development , the midgut herniates through the umbilical ring; six weeks later it returns to the abdominal cavity and rotates around the superior mesenteric artery .
The amniotic membrane and its contents form the umbilical cord that connects the embryo and the placenta. [3] [4] The root of the connecting stalk contains the allantois as a diverticulum of hindgut endoderm along with umbilical vessels. [5] [2] Anomalies are usually referred to as body stalk anomalies and occur in approximately 1 in 15,000 ...
The round ligament of the uterus originates at the uterine horns, in the parametrium.The round ligament exits the pelvis via the deep inguinal ring. [3] It passes through the inguinal canal to reach the labium majus, [4] [5] [2] inserting into the fibro-fatty substance of the labium majus.
Parts of the adult navel include the "umbilical cord remnant" or "umbilical tip", which is the often protruding scar left by the detachment of the umbilical cord. This is located in the center of the navel, sometimes described as the belly button. Around the cord remnant is the "umbilical collar", formed by the dense fibrous umbilical ring ...
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 ).
In human anatomy, the inferior epigastric artery is an artery that arises from the external iliac artery. [1]: 225 It is accompanied by the inferior epigastric vein; inferiorly, these two inferior epigastric vessels together travel within the lateral umbilical fold (which represents the lateral border of Hesselbach's triangle, the area through which direct inguinal hernias protrude. [2])
The spermatic cord in the male and the round ligament of the uterus in the female pass through the transversalis fascia at the deep inguinal ring, the entrance to the inguinal canal. This opening is not visible externally. In the male, the transverse fascia extends downwards as the internal spermatic fascia. [4]
The umbilicus (navel) is a defect in the linea alba through which foetal umbilical vessels pass before birth. [1] The linea alba is formed by the union of aponeuroses (of the muscles of the anterior abdominal wall [ 2 ] ) that collectively make up the rectus sheath .
