How to locate inferior epigastric artery?
The inferior epigastric artery is a branch of the external iliac artery. It is found on the anterior abdominal wall, passing superomedially from the inguinal canal towards the midline….Inferior epigastric artery.
| Origin | External iliac artery |
|---|---|
| Branches | Muscular branches, anastomotic branches, cremasteric artery, pubic branch |
What does the lateral umbilical fold cover?
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.

What does the superficial epigastric artery supply?
The superficial epigastric artery supplies the superficial tissue of the abdominal wall; the superior and inferior epigastric arteries make an anastomosis with each other and supply the muscles of the abdominal wall.
Where does the inferior epigastric artery enter the rectus sheath?
Clinically, the arcuate line is important as the site of entry of the inferior epigastric artery into the rectus sheath. The DIEA enters the rectus muscle in its lateral third and divides into a medial and lateral branch.
Why it is called inferior epigastric artery?
In human anatomy, inferior epigastric artery refers to the artery that arises from the external iliac artery. It anastomoses with the superior epigastric artery. Along its course, it is accompanied by a similarly named vein, the inferior epigastric vein.
What is a urachus?
(YOO-rah-kus) A fibrous cord that connects the urinary bladder to the umbilicus (navel). The urachus is formed as the allantoic stalk during fetal development and lasts through life. Also called median umbilical ligament.
What is the median umbilical fold?
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.
Where does the superior epigastric artery come from?
The superior epigastric artery is a terminal continuation of the internal thoracic artery. It originates at the level of the sixth costal cartilage and takes an inferior course, passing between the costal and xiphoid muscular slips of the diaphragm.
What is the fascia Transversalis?
The transversalis fascia is a thin layer of connective tissue lining most of the abdominal cavity between the posterior surface of the transversus abdominis and superficial to the extraperitoneal fat and peritoneum.
What is the Spigelian line?
Spigelian hernias (alternative plural: herniae), also known as lateral ventral hernias, are a type of abdominal hernia along the semilunar line, resulting in herniation between the muscles of the abdominal wall.
Can you pee out your belly button?
When the wetness is more extreme, it may be because there is an opening, or sinus, from the bladder to the belly button from which urine is leaking. When this happens, it’s called a patent urachus. Urachal abnormalities are much less common in older children or adults.
Can people pee out of belly button?
A patent urachus can cause varying amounts of clear urine to leak at the umbilicus. This occurs when the urachus did not seal close to the umbilicus and leads to a blind ending tract from the umbilicus into the urachus called a sinus.
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.
What is the ligamentum teres a remnant of?
Ligamentum teres (or round ligament) of the liver is a cord-like ligament found within the falciform ligament on the inner surface of the anterior abdominal wall and represents a remnant of the umbilical vein, which is a connecting venous structure between the placenta and the umbilical portion of the left portal vein.
What are the 3 major structures present in the femoral triangle?
The borders of the femoral triangle are composed of the inguinal ligament superiorly, the adductor longus muscle medially, and the sartorius muscle laterally.
Why is it called Hunter’s canal?
The eponym ‘Hunter’s canal’ is named for John Hunter.
