The fascial system. How many of you have heard of fascia?
00:00:0900:00:13
Good. This is your connective tissue. This is your connective tissue.
00:00:1400:00:16
It's gotten a lot more popular over the last few years.
00:00:1600:00:19
A lot more research is being done, but we're going to keep it simple today.
00:00:2000:00:22
A ligament.
00:00:2200:00:24
A ligament attaches what to what?
00:00:2500:00:27
Bone to bone.
00:00:2700:00:30
Wait a second, we already saw something that was bone to bone.
00:00:3100:00:32
What was that?
00:00:3300:00:35
Joints are bone to bone.
00:00:3600:00:38
Which means if a ligament attaches bone to bone,
00:00:3800:00:40
then it does what?
00:00:4100:00:43
Supports joints.
00:00:4300:00:47
So we're going to find ligaments at every joint
00:00:4700:00:49
because that's what helps keep them together.
00:00:5300:00:55
What do tendons do? Connect what to what?
00:00:5500:00:59
Muscle to bone, so generally speaking muscles don't attach to bones.
00:00:5900:01:01
Tendons attach to bones.
00:01:0100:01:05
So muscles pull on tendons which then moves bones...at a...
00:01:0700:01:09
which is supported by
00:01:1000:01:12
ligaments. Just putting it all together.
00:01:1300:01:15
This is the Achilles tendon.
00:01:1600:01:18
You all know where your Achilles tendon is?
00:01:2000:01:22
We'll do a little flash forward here.
00:01:2200:01:26
What muscles does the Achilles tendon attach
00:01:2600:01:28
to the calcaneus, the heel bone?
00:01:2800:01:30
Soleus and gastroc, good.
00:01:3000:01:32
The Achilles tendon is a big tendon that takes my calf
00:01:3200:01:35
and basically attaches it to my calcaneus.
00:01:3600:01:37
Got that?
00:01:3900:01:43
Fascia. When we us the term fascia without using the term as a global thing
00:01:4400:01:47
usually we're talking about sheets of connective tissue.
00:01:4800:01:52
You have things like the epimysium that covers the muscles
00:01:5200:01:54
and gives them shape.
00:01:5400:01:57
You remember epimysium, endomysium and perimysium?
00:01:5800:02:00
I won't quiz you too hard on that.
00:02:0000:02:03
But the epimysium is just a big sheet of fascia that shapes muscles.
00:02:0600:02:08
This fascia right here
00:02:1000:02:13
this very thick fascia, at least that's what I tell people.
00:02:1300:02:15
It's not fat, it's just fascia.
00:02:1800:02:22
Why would I have connective tissue over this area?
00:02:2500:02:29
Yeah, I mean is connective tissue weak or strong stuff?
00:02:3000:02:34
Strong. It's not nearly as elastic as muscle tissue.
00:02:3500:02:36
Does that make sense?
00:02:3800:02:40
You have connective tissue which is a little less elastic,
00:02:4000:02:42
a little bit more resistant
00:02:4400:02:46
over my abdominal cavity to protect
00:02:4800:02:51
maybe my internal organs, that would be probably a good thing.
00:02:5300:02:55
We have my internal organs here to protect.
00:02:5600:02:59
What is this area of my body lacking
00:02:5900:03:01
that this area of my body has?
00:03:0200:03:04
Ribs. So my thoracic spine
00:03:0500:03:07
is much more stable because of my ribcage and
00:03:0700:03:09
all the bony attachments.
00:03:1000:03:12
Another thing that this fascia does is
00:03:1200:03:14
is it helps protect my lumbar spine a little bit
00:03:1400:03:16
by keeping me from doing what?
00:03:1800:03:21
Yeah, it helps resist that motion a little bit,
00:03:2100:03:23
gives me a little bit more stability.
00:03:2400:03:27
There's actually some fascia on the other side too, we saw this picture.
00:03:2800:03:30
Anybody know what this is called?
00:03:3200:03:34
Your thoracolumbar fascia.
00:03:3500:03:38
You have seen that in every picture, I'm not sure you knew it had a name.
00:03:3900:03:43
Yeah, that fascia is there for a reason, it helps stabilize the lumbar spine as well.
00:03:4400:03:47
Interesting that we have this corset of connective tissue
00:03:4700:03:49
where we lack bony support.
00:03:5100:03:52
And there's fascia all over the body.
00:03:5200:03:54
There is definitely connective tissue all over the body
00:03:5500:03:57
supporting us, giving us shape,
00:04:0000:04:02
protecting internal organs
00:04:0200:04:04
and of course transmitting force.
00:04:0600:04:08
A little deeper into our educations, we'll see where some
00:04:0900:04:13
some of these fascial sheaths are connections for multiple muscles
00:04:1300:04:15
transferring force from one to another.
00:04:1700:04:19
Your thoracolumbar fascia,
00:04:2000:04:21
connects your glutes to your lats.
00:04:2200:04:24
That's an interesting combination of muscles.
00:04:2500:04:27
You think that would help transfer force between your
00:04:2700:04:28
lower and upper extremity?
00:04:3000:04:31
Is that important?
00:04:3100:04:34
Sure, do you pull open a door with just your arms?
