now we're going to talk about the scapula.
And the scapula is really fascinating
the free-floating bones of the body, just
like the clavicle is.
So, the clavicle scapula are the free
floating bones of the body and
they're embedded in muscles.
So, the scapula is embedded in the
It is embedded with the Teres Major, the
But I want to just kind of get into the
functionality of the scapula,
because the scapula, you know, enables
things to kind of just move around.
You know what i'm saying?
So, it's really important to understand
And to understand that, its not just
another part of the body that
is not free floating cause it's kind of
working in it's own ways, and
that's kinda what makes this really
So, I pointed out before that the scapulas
are a really good place to find landmarks.
As you could see the landmarks of the
scapula right here.
Landmarks right here.
So you kinda know where you are at.
The other things is that, when you raise
your arms up,
you notice that the scapula doesn't move
till right there.
Now, if you raise it above ninety degrees,
notice that the scapulas actually start to
Now go down.
Okay right there.
So the scapula's always flat like that.
So, I'll explain.
So if we have a rib cage.
With the scapula like this.
Well first of all,
we can see where are landmarks are.
But here, the scapula is just going to be
If your hand is down here, if your arm is
down this way,
even if your arm is this way.
The scapula will not move.
Now, when the scapula, and let me just do
it over here.
So, if you have the ribcage here and
you're 90 degrees.
That's what they look like.
Now if you raise them, let's raise them.
Then all of a sudden once the arms are
raised, there's two things that happen.
There's two things that happen.
One, that the deltoid is starting to
And it's pinching because the scapula is
actually now moving like that.
So, here you've got a pretty dynamic
pinch, the second you go over 90 degrees.
So, the arms go up, scapulas move.
The arms are here or anywhere like this,
scapulas stay still.
That's important to know.
looking at the musculature of the scapula,
it's kind of important to understand a
basic understanding of that.
Because, they're really looked upon as the
foundation of the shoulders,
foundation of the shoulder girdle.
So you could see
here is the, scapula.
The bone of the scapula.
And then here, you've got your
is your acromion.
So here is the infraspinatus
[NOISE], and right in here,
you have the bone, the humerus bone
that comes out, like that.
So, you have the humerus bone here.
Here you have your infraspinatus.
Here you have your teres minor muscle
attaching here to the back of the humerus.
Here's your teres minor.
And then you have your teres major muscle,
which is attaching to the front of that
humerus from over here.
And then of course,
you have your tricep muscle which is
attaching behind the scapula here.
I guess I could just draw over this.
That direction, don't really wanna get too
much into that, but, it is there.
So, important to note the infraspinatus
covers the majority of the scapula here.
The teres minor muscle, here, attaching to
the back of the humerus, and
the teres major muscle attaching to the
front of your humerus.
So these are, these are just kind of
some basic muscles that you should know
you look at the scapula, cuz it's
the scapula is not only beautiful, but
incredibly functional and incre dynamic,
that's what it is, the scapula is dynamic.
