Why is the inside of the stomach folded
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
