the

Peritoneal folds of anterior abdominal wall

okay so this shows the posterior aspect

of the

anterior abdominal wall this region is

the back of the umbilicus and amido it

we can see that there are three

thickening two of two of them are there

are two pairs of thick innings and one

in the midline the midline thickening is

called the median umbilical fold and

then on its lateral sides there are the

medial umbilical faults further

laterally are the lateral umbilical

folds actually the lateral Ambalika

Falls they do not reach the umbilicus

but they are called lateral medical

folds and I think that you can see

through the peritoneum here that these

folds are occupied by vessels these are

inferior epigastric vessels artery and

vein they branch from the the arteries a

branch of the external iliac artery just

before the passes beneath the inguinal

ligament and the artery ascends up and

enters into the rectus sheath this is

the rectus sheath opened from behind in

the artery passes behind the rectus

abdominis muscle the median American

fold which passes to the umbilicus is

the remnant of the Arrakis and to medial

umbilical folds and they are the remnant

of the umbilical artery umbilical artery

brings the blood from the fetus to the

mother it's deoxygenated blood now above

the umbilicus and the region above them

because there is another fold here you

can see we can follow this fold it is

located in the free lower border of the

falciform ligament this is the falciform

ligament the falciform ligament here

which is attached to the liver and in

the free lower border of the first foam

ligament is a rounded thickening a

ligamentum teres which means round

recommend mt rigi parties because it is

destined for the liver and this

represents the left umbilical vein

obliterated left and vertical vein that

carries the oxygenated

blood from the Americas from the mother

to the fetus so all in all we have six

folds one about one above the umbilicus

they mean the ligamentum TAC practice

and five falls below them but it has

median umbilical fold to medial

umbilical Falls and to lateral and

vertical folds which are vascular and

they although they are called and

vertical but they do not reach the

Americas
