Middle Umbilical Fold

	Middle Umbilical Fold Related to the urinary bladder, anteriorly there are the following folds: * one median umbilical fold on the median umbilical ligament (which in turn, contains the urachus) * two medial umbilical folds on the occluded umbilical artery * two lateral umbilical folds on the inferior epigastric vessels References External links * - "Inguinal Region, Scrotum and Testes: Umbilical Folds and Peritoneal Fossae" * () * http://www.portfolio.mvm.ed.ac.uk/studentwebs/session5/37/ALBL_Anterolateralwall.htm Pelvis Urinary system {{genitourinary-stub ...

	Abdominal Wall In anatomy, the abdominal wall represents the boundaries of the abdominal cavity. The abdominal wall is split into the anterolateral and posterior walls. There is a common set of layers covering and forming all the walls: the deepest being the visceral peritoneum, which covers many of the abdominal organs (most of the large and small intestines, for example), and the parietal peritoneum—which covers the visceral peritoneum below it, the extraperitoneal fat, the transversalis fascia, the internal and external oblique and transversus abdominis aponeurosis, and a layer of fascia, which has different names according to what it covers (e.g., transversalis, psoas fascia). In medical vernacular, the term 'abdominal wall' most commonly refers to the layers composing the anterior abdominal wall which, in addition to the layers mentioned above, includes the three layers of muscle: the transversus abdominis (transverse abdominal muscle), the internal oblique, internal (obliquus internus) a ...

picture info	Urinary Bladder The bladder () is a hollow organ in humans and other vertebrates that stores urine from the Kidney (vertebrates), kidneys. In placental mammals, urine enters the bladder via the ureters and exits via the urethra during urination. In humans, the bladder is a distensible organ that sits on the pelvic floor. The typical adult human bladder will hold between 300 and (10 and ) before the urge to empty occurs, but can hold considerably more. The Latin phrase for "urinary bladder" is ''vesica urinaria'', and the term ''vesical'' or prefix ''vesico-'' appear in connection with associated structures such as vesical veins. The modern Latin word for "bladder" – ''cystis'' – appears in associated terms such as cystitis (inflammation of the bladder). Structure In humans, the bladder is a hollow muscular organ situated at the base of the pelvis. In gross anatomy, the bladder can be divided into a broad (base), a body, an apex, and a neck. The apex (also called the vertex) is directed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Median Umbilical Fold In human anatomy, the median umbilical ligament is an unpaired midline ligamentous structure upon the lower inner surface of the anterior abdominal wall. It is covered by the median umbilical fold. The median umbilical ligament represents the remnant of the fetal urachus. It extends from the apex of the bladder to the umbilicus, on the deep surface of the anterior abdominal wall. The median umbilical ligament represents one of the five ligaments of the internal anterior abdominal wall inferior to the umbilicus; laterally on either side of it are one medial umbilical ligament and finally one lateral 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. It is also formed from the cloaca in utero. Function The median umbilical ligament has no known function. Clinical significance The median umbilical ligame ...

	Urachus The urachus forms from the distal end of the allantois in the embryo, and develops into a closed cord between the base of the bladder, and the navel. It drains the 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. At birth, the urachus develops into the median umbilical ligament. Development The part of the urogenital sinus related to the bladder and urethra absorbs the ends of the Wolffian ducts and the associated ends of the renal diverticula. This gives rise to the trigone of the bladder and part of the prostatic urethra. The remainder of this part of the urogenital sinus forms the body of the bladder and part of the prostatic urethra. The apex of the bladder stretches and is connected to the umbilicus as a narrow canal. This canal is initially open, but later closes as the urachus goes on to definitively form the median umbilical li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Medial Umbilical Fold The medial umbilical fold is an elevation of the peritoneum (on either side of the body) lining the inner surface of the lower anterior abdominal wall formed by the underlying medial umbilical ligament (the obliterated distal portion of the umbilical artery) which the peritoneum covers. Superiorly, the two medial umbilical folds converge towards the midline to meet and terminate at the umbilicus. The unpaired midline median umbilical ligament In human anatomy, the median umbilical ligament is an unpaired midline ligamentous structure upon the lower inner surface of the anterior abdominal wall. It is covered by the median umbilical fold. The median umbilical ligament represents the re ... lies medially to each medial umbilical fold; a lateral umbilical fold lies lateral to either medial umbilical fold. A supravesical fossa lies between the median umbilical fold and either medial umbilical fold on either side. A medial inguinal fossa lies between the median umbilical fold and ...

	Umbilical Artery The umbilical artery is a paired artery (with one for each half of the body) that is found in the abdominal and pelvic regions. In the fetus, it extends into the umbilical cord. Structure Development The umbilical arteries supply systemic arterial blood from the fetus to the placenta. Although this blood is sometimes referred to as deoxygenated blood it is not, and has the same oxygen saturation and nutrients as blood distributed to the other fetal tissues. There are usually two umbilical arteries present together with one umbilical vein in the umbilical cord. The umbilical arteries surround the urinary bladder and then carry all the deoxygenated blood out of the fetus through the umbilical cord. Inside the placenta, the umbilical arteries connect with each other at a distance of approximately 5 mm from the cord insertion in what is called the ''Hyrtl anastomosis''. Subsequently, they branch into chorionic arteries or ''intraplacental fetal arteries''. The umbilical arter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Lateral Umbilical Fold The lateral umbilical fold is an elevation (on either side of the body) of the peritoneum lining the inner/posterior surface of the lower anterior abdominal wall formed by the underlying inferior epigastric artery and inferior epigastric vein which the peritoneum covers. Superiorly, the lateral umbilical fold ends where the vessels reach and enter the rectus sheath at the arcuate line of rectus sheath; in spite of the name, the lateral umbilical folds do not extend as far superiorly as the umbilicus. Inferiorly, it extends to just medial to the deep inguinal ring. Each lateral umbilical fold is situated lateral to the ipsilateral medial umbilical fold. Unlike the median and medial umbilical folds, the contents of the lateral umbilical fold remain functional after birth. Clinical significance The lateral umbilical fold is an important reference site with regards to hernia classification. A direct hernia occurs medial to the lateral umbilical fold, whereas an indirect hernia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	Pelvis The pelvis (: pelves or pelvises) is the lower part of an Anatomy, anatomical Trunk (anatomy), trunk, between the human abdomen, abdomen and the thighs (sometimes also called pelvic region), together with its embedded skeleton (sometimes also called bony pelvis or pelvic skeleton). The pelvic region of the trunk includes the bony pelvis, the pelvic cavity (the space enclosed by the bony pelvis), the pelvic floor, below the pelvic cavity, and the perineum, below the pelvic floor. The pelvic skeleton is formed in the area of the back, by the sacrum and the coccyx and anteriorly and to the left and right sides, by a pair of hip bones. The two hip bones connect the spine with the lower limbs. They are attached to the sacrum posteriorly, connected to each other anteriorly, and joined with the two femurs at the hip joints. The gap enclosed by the bony pelvis, called the pelvic cavity, is the section of the body underneath the abdomen and mainly consists of the reproductive organs and ...
