Muscular and Fascial System 2: Video #23 of Introduction to Functional Anatomy
This video is a comprehensive introduction to the anatomy of the muscular and fascial systems. It covers the origin and insertion points of the major muscles, how they move and attach, and the role of fascial tissue in stabilizing the body. The video also includes illustrations of different muscle groups, demonstrating how they interact with other tissues and structures. The materialis presented in an easy-to-follow, step-by-step manner and is suitable for learners of all levels.

You guys already know the three rules of
00:00:0500:00:10
muscles we talked about it yesterday, but
00:00:1000:00:16
the muscular system, all of the muscles that cross a joint are going to play a
00:00:1600:00:26
role in joint motion, all of them. Think about that for a second. All of them have
00:00:2600:00:31
a role to play. So when we learned all the muscles of the shoulder yesterday, and we
00:00:3100:00:35
learned that the pectoralis did this, and the posterior deltoid did that, and the rotator
00:00:3500:00:42
cuff did this, realize anytime you move they're all on, doing something. All
00:00:4200:00:48
muscles act in multiple planes to concentrically accelerate, isometrically
00:00:4800:00:55
stabilize, and eccentricly decelerate motion. Another one of those things for
00:00:5500:01:01
you guys to start letting circle in the back of your head, every muscle you can
00:01:0100:01:06
think of has its function are those three functions depending on what the
00:01:0600:01:15
movement is. Some muscles and this is this is one of the next steps in your
00:01:1500:01:21
learning, in your analysis which we started working on yesterday, is to start
00:01:2100:01:28
thinking in functional groups. The reason I graph you guys to death is to start
00:01:2800:01:35
getting you to think in groups of muscles, not just oh yeah my PEC does
00:01:3500:01:41
this, that's great if all you're going to do is be a gym rat. If you're going to be
00:01:4100:01:43
more than a gym rat you're going to create some really sophisticated
00:01:4300:01:47
routines to push performance forward regardless of the sport, from
00:01:4700:01:52
bodybuilding, powerlifting to basketball to football to lacrosse
00:01:5200:01:56
whatever it happens to be, you're going to have to think a little bit bigger
00:01:5600:02:02
than that. When I say internal rotators of the shoulder, you better be thinking
00:02:0200:02:07
more than pectoralis, you guys with me.
00:02:0900:02:13
The fascial system, we talked a little bit about what the fascial system does. We
00:02:1300:02:15
talked about it a little bit this morning ,we talked about a little bit
00:02:1500:02:19
during core, let's talk about how it affects movement. It transmits force from
00:02:1900:02:23
one muscle to another, right there's some of these pieces of fascia I told you
00:02:2300:02:26
like, we keep talking about this thoracolumbar fascia, it also connects my
00:02:2600:02:33
glute to my latissimus dorsi. So it'll help transmit force from lower extremity to upper
00:02:3300:02:38
extremity providing I have a nice stable core through this piece of fascia, it'll
00:02:3800:02:47
help. It'll restrict motion if it becomes adaptively shortened. So if a fascial
00:02:4700:02:56
system becomes tight or bound one layer to another, that's going to affect motion.
00:02:5600:03:03
Elastic recoil that you were just talking about the elastic limit right. So
00:03:0300:03:08
the elastic limit of fascia is different from the plastic limit, we could get
00:03:0800:03:16
really really far on this, but just power movements what you're kind of doing is
00:03:1600:03:24
taking fascia into its elastic limit, what do you guys know of elastic bands
00:03:2400:03:28
they'll break them if you take them all the way too far, so you can't take them
00:03:2800:03:32
too far, that is kind of what happens during a strain right. But if I take it
00:03:3200:03:41
to an elastic limit and then I let go what happens? Force is produced right, the
00:03:4100:03:50
fascia didn't contract it recoiled. Power training is about matching that to what
00:03:5000:03:54
other thing that's going to help you produce force? Concentric contraction of
00:03:5400:04:02
muscles, you guys with me there on top of stretch reflex.
00:04:0200:04:06
So that's part of how the like, you guys have heard of plyometrics before right,
00:04:0600:04:13
it's an eccentric load, stimulate my attic reflex, take fascia into that
00:04:1300:04:20
elastic range, and then I consciously concentrically contract and try to match
00:04:2000:04:30
those three things. Oh densely invested with proprioceptors. There is a good
00:04:3000:04:37
chance that fascia is a sensory organ unto itself. That little thing we just
00:04:3700:04:48
did right fascia is densely invested with receptors. I have a little fascial
00:04:4800:04:52
hypothesis that these big pieces of fascia like your thoracolumbar fascia,
00:04:5200:04:58
your abdominal sheath, your iliotibial band are like nature's motherboard. You guys
00:04:5800:05:04
know a little bit about computers right, what does a motherboard do in a computer?
00:05:0400:05:11
It holds a lot of vital stuff right so that this information can ping off the
00:05:1100:05:17
motherboard and go back and do whatever the computer needs to do. From the way I
00:05:1700:05:22
see this fascial research, one of the things that we can start to look at is
00:05:2200:05:27
if two muscles connect to the same fascial sheath there might be something
00:05:2700:05:35
there about how those receptors within that fascia affect the tone. That's not
00:05:3500:05:39
the fake tone that's not how it looks, but the activity level of those two
00:05:3900:05:44
muscles and how that's going to affect a motor plan. If you pull on this fascia it
00:05:4400:05:49
might tone up this, muscle tone down this muscle which is going to affect force
00:05:4900:05:55
production and how we move. Does that make sense? It'll make a little bit more
00:05:5500:05:58
sense once we go through all the roles muscles can play.
