What’s up. Meditay here and in this video, we’ll be going through
0:06
the Fascia you’ll find in the Abdomen. So the fascia of the abdomen vover the
Muscles of the Abdomen
0:11
muscles of the abdomen from both the external and internal side. So here I’ve cut through all the
0:16
muscle layers of the abdomen. And remember, they consist of the external oblique, Internal Oblique
0:22
and Transverse Abdominal Muscle. These three at considered as the lateral abdominal muscles.
0:27
And we have the Anterior abdominal Muscles, like the Rectus Abdominis.
0:30
Our goal in this video is to go through the fascia that you’ll find wrapping around these muscles,
0:36
and separating them from the organs within the abdominal cavity

So In this video, we’re going to go through the Superficial Fascia,
0:43
we’ll go thrgouh the Investing Abdominal Fascia. And we’ll go thrgouh the Endoabdominal Fascia.
0:48
And to do that, we’ll have to make a transverse cut of the abdomen. Remove the upper half,
0:53
and look at it from this perspective. And now we’re gonna try to draw all
0:57
the structures and go through them as we do that. First we have the Skin.
1:01
And right underneath the skin layers, we’ll find the adipose tissue, or fat cells. Underneath the
1:07
fat cells, we can find the External Oblique. Internal Oblique, and Transverse Abdominal
1:12
Muscle. And in the middle here we can find the Rectus Abdominis muscle. So this is a very
1:16
schematic outline of the abdominal muscles. The first fascia we’re gonna go thrgouh is
Superficial Fascia
1:21
associated with the fat Layer. The fascia that cover the fat layer from the superficial side
1:26
is called Fascia of Camper. And the fascia that cover it from the inner side, is called
1:31
Fascia of Scarpa. The two layers of fascia together, form the so called Superficial Fascia.
1:38
So that’s the first one in our list. Next we have a Fascia called Investing Abdominal Fascia.
Investing Abdominal Fascia
1:45
And as the name implies, this fascia is going to surround the abdominal muscles.
1:49
So the investing abdominal fascia si divided into three layers.
1:54
First is the Superficial investing abdominal fascia, aurrounding the external oblique.
1:59
Then there’s the Intermediate Investing abdominal fascia, surrounding the internal Oblique.
2:04
Then there’s the Deep investing abdominal fascia, surrounding the transverse abdominal muscle. Now.
2:10
Underneath the Deep investing abdominal fascia, that’s where you’ll find the third fascia we’re
Endoabdominal Fascia
2:15
gonna talk about, called the endoabdominal fascia. And just underneath the endoabdominal fascia,
2:21
that’s where you’ll find the Parietal peritoneum, which over all of your internal organs.
2:28
Now, the endoabdominal fascia is actually divided into certain parts depending on the location of
2:34
it, So let’s look at that a little bit. So now we’re gonna draw the lateral view of he abdomen.
2:38
First we have the Skin, then the Fat cells, then The external oblique, Internal Oblique and
2:44
Transverse Abdominis. Deeper to those muscles, we’ll find the endoabdominal fascia. And here
2:50
just to orientate, we’ll add a perfectly drawn diagphragm, and add the quadratus Lumborum muscle.
2:56
Now the endoabdominal fascia gets different names depending on its location. If we’re
3:01
looking at the endoabodminal fascia from the abdominal part, it’s going to get the name
3:06
Transversalis Fascia. If the endoabdominal fascia is in the Pelvis, it’s called the Iliac Fascia. It
3:12
has some other names aswell depending on the region, but the transversalis fascia and the
3:16
iliac fascia are the most important ones to know when you’re studying the fasica of the abdomen.
3:21
And again, just underneath the endoabdominal fasica is the parietal peritoneum.
3:25
And that my friends, are the three fascia that I wanted to talk about in this video.
