So now let's move on to the uterus and specifically
the broad ligament. Now the
broad ligament is essentially
a peritoneal ligament. And because it is
a peritoneal ligament, it has those two layers.
And it's a consequence of the peritoneum
draping down over the pelvic
organs. Now the uterus projects from within the
pelvis, it can actually project slightly
into the greater pelvis. And as the
peritoneum is draping down, it covers
both the anterior and the
posterior surface of the uterus.
So we can see we will have peritoneum
running down what is this posterior
surface of the uterus.
This is the posterior view.
So we will have peritoneum running down on
this side. And we will also have peritoneum running down
on the more anterior side.
So where the lateral margin
of the uterus finishes;
so where the lateral marginal of
the uterus finishes here and here,
the peritoneum laterally comes
together to form this sheet.
The peritoneum comes together to form this sheet.
And it’s this double layer of peritoneum
either side of the uterus
that is the broad ligament.
It is draping down from these structures.
This is your uterine tube here.
And your uterine tube here. It is
hanging down from this uterine tube.
So if I was the broad ligament,
if I personally was the uterus,
and my arms could
be the uterine tubes,
then if a sheet was put over me, then it lay
down my anterior and posterior parts of my
uterus. But it also drape
down like a table cloth
from the uterine tube. And as it's
draping down these two layers
are pushed together. And these two
layers together which we can see here
and here is the broad ligament.
This peritoneal ligament that
helps to stabilize the uterus.
The uterus itself is a hollow
organ. It has thick walls
and it’s found mostly in the lesser pelvis.
The fundus can sometimes creep up
into the greater pelvis. So we
can see it has a nice body here.
It has an neck which is
continuous with the cervix
and that's form a
connection with the vagina.
And we can see this fundus at the top
here and then projecting via laterally
we have the uterine tubes.
As I have mentioned the body lays
between two layers of peritoneum
and laterally they unite
to form the broad ligament.
The broad ligament itself can
be divided into three specific
ligaments called the mesovarium, the mesosalpinx
and the mesometrium and you can see these
on the diagram. So what
you are looking at?
You can see the uterus here and the fundus here.
Here you can see our uterine tubes.
And the portion of the uterine
tube that is covered by peritoneum.
So uterine tube, covered by the
peritoneum, that piece of peritoneum
is called the mesosalpinx.
So this sheet which we can see
running here. This is the mesosalpinx.
And this specific part of the
broad ligament that
covers the uterine tube.
There is also a portion of the
broad ligament that covers the ovary which
you can see here. And this is known as the mesovarium.
So this region that covers the ovary,
the ovary attach to the posterior surface
of the broad ligament is viewed on its
posterior surface is known as the mesovarium.
The remainder of the broad ligament,
so this region around here,
is known as the mesometrium.
So within the broad ligament, there are
three divisions, three parts.
The part associated with the
uterine tube is the mesosalpinx.
The part associated with
the ovary is the mesovarium.
And the portion that is associated
with the rest of the broad ligament,
is the mesometrium, so three parts.
The board ligament passes over the ovarian
vessels as the suspensory ligament.
So if we follow from the ovary here, we can
see we have some ovarian blood vessels.
Remember the ovarian arteries coming from the aorta.
The ovarian vein drains into the left
renal vein or they drain into the IVC.
And these blood vessels are suspended
themselves within a ligament.
And that ligament and extension of the broad
ligament laterally is known as the suspensory ligament.
We also have some other thickenings
within the broad ligament that
connects various structures.
And between the lateral wall of the uterus and the
ovary, we find we have the ligaments of the ovary.
So here we have got the uterus, here we have got the
ovary. Running between the ovary and the uterus
we have the ovarian ligament which we can see here,
the ovarian ligaments or the ligaments of the ovary.
We also have that portion of the
broad ligament that contains
a specific thickening
which is... that passes to the inguinal canal.
And that's known as the round
ligament of the uterus.
The round ligament of the uterus
follows a similar path
as that to the vas deference in the
male and it passes laterally and then forwards
heading towards the deep inguinal
vein. It’s the consequence of
embryological development and it follows like I said,
a similar path of testes and heads towards the
the deep inguinal vein and that
is the round ligament of the uterus.
