If we move onto the peritoneal relations
associated to the liver.
These are important in enabling
the liver to be suspended from the diaphragm
If you remember, this is the superior view
looking down onto the liver
then this is posterior here, this is anterior here.
Then again we have got these
layers of peritoneum that are running
along the surface so we have got
visceral peritoneum running on the surface.
These two layers converge and then
migrate towards the anterior abdominal wall
here as the falciform ligament.
These two penitential layers.
They also come up in this direction.
They also extend up in this direction.
And that's what we can see in other diagram over here.
where it’s passing upwards
and it's passing upwards. Now, over here
we have the diaphragm. So this
image here is projecting the diaphragm
and then the coronary ligament
running over the surface of the liver then
reflex to the diaphragm so then run along
the underside of the diaphragm. And we have two of these.
We have one running around here.
And we have one running around here.
And this ligament here, and this
ligament here form the coronary ligaments.
This coronary ligament has
got this anterior and the posterior layer.
Anterior layer here and
the posterior layer here.
Remember the peritoneal ligaments
have these two layers through them.
So this is the anterior and
the posterior layer of the peritoneal ligament.
We can now see that the liver
is actually suspended from the diaphragm.
We can see now that we have this space
that doesn't have any peritoneum space on the liver.
That doesn't have any peritoneum adhere to it; because,
we have got this reflection here and here.
No peritoneum here. And that means this
region of liver is known as the bare area.
There is no peritoneum attached
to this bare area.
There are some other ligaments that
are attach the liver to the
lateral, to the right body wall and
to the left body wall, to the diaphragm.
And these are known as the triangular ligaments.
Where this bare area here doesn't contain any peritoneum.
Where this anterior layer of coronary ligament
here converge with the posterior coronary ligament
which we round underneath here.
We have left and right triangular ligament.
Where these anterior layers of the
coronary ligaments converge at the extreme.
Together, the coronary ligament and the triangular ligament
are important in suspending the liver
from the diaphragm, from
the body wall holding it in place.
We also have the inferior vena cava
running up through the liver specially on this
posterior surface and that
helps to anchor the liver in place also.
