Medial Inguinal Fossa
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. Clinical significance It is associated with direct inguinal hernias. See also * Lateral inguinal fossa The lateral inguinal fossa is a structure described in human anatomy. It is a shallow concave stretch of peritoneum on the deep surface of the anterior abdominal wall and is best seen from the greater peritoneal cavity, looking anteriorly (as, for ...

Inguinal Triangle
In human anatomy, the inguinal triangle is a region of the abdominal wall. It is also known by the eponym Hesselbach's triangle, after Franz Kaspar Hesselbach. Structure It is defined by the following structures: * Medial border: Lateral margin of the rectus sheath. * Superolateral border: Inferior epigastric vessels. * Inferior border: Inguinal ligament. This can be remembered by the mnemonic RIP (Rectus sheath (medial), Inferior epigastric artery (lateral), Poupart's ligament (inguinal ligament, inferior). Clinical significance The inguinal triangle contains a depression referred to as the medial inguinal fossa, through which direct inguinal hernias protrude through the abdominal wall.MedNote.

Lateral Umbilical Fold
The lateral umbilical fold overlies the inferior epigastric artery (a branch of the external iliac artery) and its accompanying veins. 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. 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 originates lateral to the fold. This latter case is due to the placement of the opening of the deep inguinal ring in the space lateral to the lateral umbilical fold, which allows the passage of the ductus deferens, testicular artery, and other components of the spermatic cord in men, or the round ligament of the uterus in women.

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''). It is different from the median umbilical ligament, a structure that represents the remnant of the embryonic urachus. Origins It represents the remnant of the umbilical arteries, which serves no purpose in humans after birth, except for the initial part that becomes the adult superior vesical artery. The occluded part of umbilical artery becomes the medial umbilical ligament postnatal. The medial umbilical ligament arises from the anterior division of the internal iliac artery. Functions It may be used as a landmark for surgeons performing laparoscopic procedures to help identify and avoid damaging the inferior epigastric arteries during port placement. Other than this, it has no purpose in an adult and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superficial Inguinal Ring
The inguinal canals are the two passages in the anterior abdominal wall of humans and animals which in males convey the spermatic cords and in females the round ligament of the uterus. The inguinal canals are larger and more prominent in males. There is one inguinal canal on each side of the midline. Structure The inguinal canals are situated just above the medial half of the inguinal ligament. In both sexes the canals transmit the ilioinguinal nerves. The canals are approximately 3.75 to 4 cm long. , angled anteroinferiorly and medially. In males, its diameter is normally 2 cm (±1 cm in standard deviation) at the deep inguinal ring.The diameter has been estimated to be ±2.2cm ±1.08cm in Africans, and 2.1 cm ±0.41cm in Europeans. A first-order approximation is to visualize each canal as a cylinder. Walls To help define the boundaries, these canals are often further approximated as boxes with six sides. Not including the two rings, the remaining four sides are usually cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct Inguinal Hernia
An inguinal hernia is a hernia (protrusion) of abdominal-cavity contents through the inguinal canal. Symptoms, which may include pain or discomfort especially with or following coughing, exercise, or bowel movements, are absent in about a third of patients. Symptoms often get worse throughout the day and improve when lying down. A bulging area may occur that becomes larger when bearing down. Inguinal hernias occur more often on the right than left side. The main concern is strangulation, where the blood supply to part of the intestine is blocked. This usually produces severe pain and tenderness of the area. Risk factors for the development of a hernia include: smoking, chronic obstructive pulmonary disease, obesity, pregnancy, peritoneal dialysis, collagen vascular disease, and previous open appendectomy, among others. Predisposition to hernias is genetic and they occur more often in certain families. Deleterious mutations causing predisposition to hernias seem to have domina ...

Lateral Inguinal Fossa
The lateral inguinal fossa is a structure described in human anatomy. It is a shallow concave stretch of peritoneum on the deep surface of the anterior abdominal wall and is best seen from the greater peritoneal cavity, looking anteriorly (as, for example, during laparoscopy). Boundaries It is a shallow depression on the inner aspect of the abdominal wall lateral to the lateral umbilical fold. Clinical significance It is a site of herniation for indirect inguinal hernia.
