So we're going to go over anatomical
positions, anatomical directions,
anatomical planes. We're going to go over a whole lot of vocab in the beginning.
What you first need to realize is that functional anatomy more than anything is
just a language and like learning any language, at first, it's not going to make
any sense. And then as you get more words together, you start seeing how everything
fits and you start realizing that there's a logic behind anatomy. Hopefully
by the end of the day you are going to start to put some big groups of
pieces together and you'll be like, "Oh yeah," this isn't just a bunch of random
words in Latin. Let's start with anatomical position. Everybody stand
up. Everybody stand in the anatomical position. Oh yeah, so that's eyes facing
forward, I don't know why they have to specify eyes but they do. Palms forward,
feet forward. Is this ideal posture? No, obviously we do not walk around with
our palms forward. It would be a little weird and I hope you use your eyes to track more
than the things directly in front of you. But what is anatomical position good for?
It's a reference point. So when we start talking about muscles, at least initially,
you got to learn joint actions, you have heard the term
joint actions before? So when we talk about joint actions, what joint
action a muscle will cause, we're generally talking about from this position,
initially. Does that make sense? When we talk about something called anatomical
directions, we're generally referring to where something is based on your body
being in anatomical position. Does that make sense? Everybody one more time, show
me anatomical position. Engrain it in your mind, etch it, laser it, build an
app for it, something. Next, you can go ahead and sit.
Anatomical directions, how many of you have heard of anatomical directions
before? How many you have heard of directions before? How many of you guys
have given directions before? How many of you just gave up and went GPS? No?
All right so directions, we need directions in the human body just like
we need directions to get someplace. We just use a little different words.
Let's start with the first two. Each one of these is in pairs. We got superior
and inferior. Well if I tell you that your boss is superior to you, what does
that mean? Above and in the human body, superior means the same thing. Superior
means above. If you hire on an intern and you're the boss your intern is what?
Inferior to you, which means below. Probably not a good thing to tell your
intern, that's not going to help their confidence any. But you get
superior versus inferior? Superior might be in this direction,
inferior is going to be in this direction, generally if we're talking
from the anatomical position. We're going to play a little game here in a second.
Medial versus lateral. What does medial sound like? Middle, so where would the
middle of your body be? Yeah, directly down the center line. What about
lateral, what do you do that has the word lateral in it? Raise your
arm. How many you guys who do lateral raises? Nobody's done a lateral raise? I
don't have that many gym rats in here yet? Some lateral raises for your
shoulders. Lateral raises are in which direction? Towards the outside, so
lateral is the opposite of medial and is toward the outside. Anterior
and posterior. Anybody ever been told to sit on their posterior? Has anybody ever
been told that? Good. I'm glad I wasn't the only one growing up, "Sit on your
posterior." Where's your posterior? Your backside.
So what do you think anterior means? Front. Anterior and posterior delt.
Where's your anterior delt? Everybody touch your anterior delt. Palpate.
Everybody knows what the definition of palpate is? To touch in a professional
manner. Posterior delt is where? Everybody palpate their posterior delt.
Good good good good good. These are probably the tricky ones: proximal and
distal. How many of you have heard these terms before? Proximal.
What does that word sound like? Proximity. Proximity means what? Close. Now the
question is close to what? What are we talking about being close to? Well, in the
human body, it's the trunk. You can think of putting a little bull's eye right
here, right over your bellybutton. All right so it's in proximity to this. Now
distal sounds like what word? Distance, so now we got to think what's the furthest
distance from this proximal point? What would be the first farthest things from
this? Fingers and toes. You almost have to think of proximal and distal
as if your body was like this. That make sense? Then we have supine and prone.
You know these? Supine, face or palm up when lying on back. The way
I was taught how to remember this is if you hold a bowl of
soup right you are supine and then if you pro it out... oh it's only going to get
cheesier. I know that was bad right. Wasn't it? All right so everybody supine,
pro. Good all right so everybody's got their anatomical directions. Think
you got this? All right stand up, because now we get to play a really fun
game. It's called "Brent Says." It's why I think it's a fun game. Why
are we going to play "Brent Says?" Because actually it's really annoying to say
"Simon Says" after every direction that I give you. So here's what I want you
to do. Touch the posterior aspect of your head. Good. Touch the anterior aspect of
your head. Good so now we're on your face. Let's let's do the
lateral aspect of your face. Good. Didn't get anybody yet. Medial aspect of your
face, your nose would be medial. Could you have touched here too? Yeah that's still
mid-line. What about here? All right so we all got we got medial down. Good let's do
the superior portion of your face.
Proximal portion of your face. Oh got you got you, where's proximal portion of your
face? What's proximal mean? Closer to the torso right? So this would be the
proximal portion of your face. What would be the inferior portion of your face?
Same spot. Same spot. What would be the distal portion of your face?
Let's mix this up a little bit, let's mix this up. What do I got for you?
Let's do...medial trunk. Good.
Superior shoulder. Posterior thigh. Anybody else feel like they're playing
anatomy twister. I just kind of realized that. We need a
little spin thing. All right let's do lateral trunk. Let's do proximal arm.
Yeah so it'd be your proximal arm, your shoulder. Let's do distal arm. Anterior thigh.
Let's do inferior shoulder. Got a couple of you. I started mixing up the
pairs and I got a couple of you already. How you doing though, you still
getting it? Should we really take it up a notch? How many of you guys are ready for
groupings? You ready for groupings? Touch your, you can think about
this one for a second, remember this ain't Jeopardy. No points for answering first.
Where's your anterolateral, anterior and lateral, trunk? Yeah so I'd be referring
to anything here. Anterolateral. All right let's do posteromedial head.
Everybody feel that bump on the back of their head? You ready for a fancy
word? It's called your external occipital protuberance. Right there, got that?
Anybody know what muscle inserts into that? None nobody? Your traps, they come to your
external occipital protuberance, that's just a little prelude to what's to come.
Let's do, oh I like this one let's do the dorsal, did I explain dorsal?
I didn't explain dorsal, how did I not explained dorsal? So I told you you
got anterior and posterior. Occasionally, you are going to hear
reference to other anatomical directions, like ventral or dorsal. Ventral generally
means forward, dorsal what does that word sound like? You know a word that has
dorsal in it. Dorsal fin. Like on a shark, like jaws right like the dorsal
fin - tun tun tun tun tun. You got the dorsal fin, where is that located on
an animal? Back or top surface. Or you'll also hear dorsal
referred to as like the top surface of something, like your foot.
I gave away the next one but I'm going to still make
you do it anyway. I want you to touch the dorsal aspect of your distal,
everybody still with me, lower extremity.
You can immediately tell who has flexible hamstrings in this room because
about two-thirds of you went like this and then by a third of you went, "Screw
that!" All right let's do the posterior and proximal aspects, posterior proximal
aspect of your lower extremity. That's right, I got you all palpating your
glutes, what? We'll find out later why the glutes are my favorite muscle.
It's true, it's true. There's a big functional reason for that. All right you
can sit. You think you got anatomical directions down a little bit?
