Adductors, peanut butter leaves me greasy.

What? What did he just say? My favorite acronym in all of anatomy, peanut butter
00:00:2800:00:43
leaves me greasy. Pectineus, adductor brevis, adductor longus, adductor Magnus and
00:00:4300:00:54
gracilis. These are more or less in order of attachment on the femur to. Till here
00:00:5400:00:59
and then its attachment on the tibia, but you guys get what I'm saying. So the
00:00:5900:01:04
adductors kind of go like this, they kind of splay out, each one getting a little
00:01:0400:01:14
longer than the last one, as you can kind of see in this picture. Anybody have a
00:01:1400:01:25
dog, have you ever fed a dog peanut butter? So I had this dog growing up
00:01:2500:01:35
named Amigo he was a great dog, he was a 40-pound rich Chihuahua. No I know that would be a
00:01:3500:01:40
monster Chihuahua. Dingo is my only monster Chihuahua, 22 pounds. He was a,
00:01:4000:01:46
Amigo was a retriever lab mix with one ear up and one ear down all the time,
00:01:4600:01:51
super super cute dog. But I had this thing when I was in high school, he used
00:01:5100:01:54
to love to come home and have peanut butter on a bagel. Has anybody ever had
00:01:5400:01:59
peanut butter on a bagel, delicious, delicious. Super high in calories too, which is
00:01:5900:02:03
probably why I enjoyed it so much as I was growing a lot in high school right.
00:02:0300:02:09
But amigo would always beg for the peanut butter, always beg for the peanut
00:02:0900:02:18
butter, so what did i do? You know exactly what I did. I did the nicest and meanest
00:02:1800:02:26
saying I could ever do to amigo, I took a big finger full of peanut butter, right
00:02:2600:02:31
behind his teeth; because what did it do?
00:02:3200:02:39
He walks away with his tail wagging, like 20 minutes later tail not so wagging
00:02:3900:02:47
anymore, still sucking on the back of his teeth, and my when, as soon as I saw
00:02:4700:02:51
peanut butter leaves me greasy, I don't remember where I got this, that was the
00:02:5100:02:57
first thing I thought of, is poor Amigos greasy little mouth and I'm trying to
00:02:5700:03:02
get that peanut butter out of his back teeth. He was happy for most of it, it was
00:03:0200:03:06
just at the end he would start getting a little annoyed. Alright so hopefully that
00:03:0600:03:10
helps you guys remember your five - pectineus, brevis, longus, Magnus, gracilis,
00:03:1000:03:15
adductors; and if you remember them in this order, it does become a little
00:03:1500:03:20
helpful to remember which ones do what actions. So being that these are called
00:03:2000:03:25
the adductors, what do we think they probably do? I'm going to guess a
00:03:2500:03:29
adduction, just a thought.
00:03:3400:03:50
I don't have a pelvis over there, oh I do have a pelvis over here. This is your
00:03:5000:03:58
pelvis alright, and then this pelvis is broken too, it's got a lot of broken
00:03:5800:04:04
bones around here alright. So can you guys see how the pubis for the most part
00:04:0400:04:11
lies in front of the hip, guess where most of the adductors start, pubis
00:04:1100:04:18
right so they all go from pubis to femur; which means they'll probably contribute
00:04:1800:04:28
to a little bit of what? Good call, as well as a little bit of flexion right,
00:04:2800:04:32
because they're in front of the hip. So they'll contribute a little bit
00:04:3200:04:37
flexion, a little bit to internal rotation, as well as a whole lot to
00:04:3700:04:43
adduction. Have a spine.
00:04:4600:05:01
So we start there, this is what the adductors do, all of them, I guess I'll
00:05:0100:05:23
write down a little nicer, but we have a couple with some special functions. the
00:05:2300:05:33
gracilis is the only adductor to cross the knee, all right and it crosses behind
00:05:3300:05:42
the knee and attaches to the inside of the tibia. So other than these the
00:05:4200:05:47
gracilis will also contribute to what? If it goes behind the knee then it
00:05:4700:06:02
contributes to? Knee flexion. If attaches to the inside of the tibia? Tibial
00:06:0200:06:05
internal rotation.
00:06:1000:06:20
Nice job, we only have one more addition to this. And it's the muscles so big we
00:06:2000:06:26
literally have to divide it in two. Magnus means big right, like that's what that
00:06:2600:06:31
word means. Anybody watch the strongman competitions? You guys remember Magnus
00:06:3100:06:40
Ver Magnuson. I'm like really, your name is big ver son of big. That's literally
00:06:4000:06:45
what your name translates to, and you're a strongman competitor, go
00:06:4500:06:53
figure right. But you're adductor Magnus is kind of the same thing, it's huge. So I
00:06:5300:06:59
talked about most of your adductors attached to your pubis. This is your
00:06:5900:07:07
ischium right, you're adductor Magnus is so big it goes from pubis to ischial
00:07:0700:07:14
tuberosity. So you have a group of fibers that run in front of the hip, and then a
00:07:1400:07:25
posterior head that actually runs behind the hip right, you guys with me. So the
00:07:2500:07:32
anterior portion of the adductor Magnus we're fine with, however we have to make
00:07:3200:07:44
like a note here that the posterior adductor Magnus if it goes behind the hip,
00:07:4400:07:55
what is it going to contribute to? Extension and external rotation, is it
00:07:5500:08:02
still going to contribute to adduction? Yes it's an adductor,
00:08:0400:08:11
fair enough. Has anybody ever felt there aductor Magnus before, soreness. This is
00:08:1100:08:15
actually a very common place, we'll talk about it a little bit when we get to
00:08:1500:08:21
postural dysfunction; where somebody will do leg workouts and they'll continuously
00:08:2100:08:27
get sore and like the back of their inner thigh, not their glute the back of
00:08:2700:08:30
their inner thigh, and what that generally means is they're adductor
00:08:3000:08:35
Magnuss is working harder than it should, and who's not working as hard as they
00:08:3500:08:48
should, the glutes exactly. Alright flexors and extensors of the hip. Alright
00:08:4800:08:56
so hip flexion and extension,
00:09:1000:09:32
who does flexion? Who else does flexion? Psoas, iliacus, TFL, rectus femoris, glute min
00:09:3200:09:42
nice call, adductors everybody except
00:09:4200:09:48
posterior head of addductor magnus which goes over here.
00:09:5100:09:58
Alright who else does extension, who's the big one? Glute Max.
00:10:0600:10:11
You're going to have to name those. So I'm going to end in fact let's break it
00:10:1100:10:19
all the way down hamstrings, medial are,
00:10:1900:10:29
here's what I hear from you guys it's like semitendinosis, so that's semi
00:10:2900:10:55
tendinosis, semimembranosus and then who's my lateral? Biceps femoris. For
00:10:5500:11:04
another exciting graph, oh maybe not that far, but hip internal rotators? TFL good
00:11:0400:11:16
call, gluteus minimus, not medius, adductors,
00:11:2100:11:25
medial hamstrings good,
00:11:3300:11:43
pectineus is part of this adductors right. So this is PBLMG -pectineus. What
00:11:4300:11:55
was that? Anterior, yeah that would be here, which means if anterior Magnus as
00:11:5500:12:02
well as all the other adductors are here, who's here? Posterior.
00:12:1400:12:22
Yeah let's let's just leave piriformis as an external rotator, that's kind of like
00:12:2200:12:27
somebody said gluteus medius, well technically gluteus medius has anterior
00:12:2700:12:31
and posterior fibers and the anterior fibers do internal rotation, what we need
00:12:3100:12:35
to worry about is the posterior fibers that get weak, and our external rotators
00:12:3500:12:43
and are probably in need of a little work. Medial hamstrings all right so lets
00:12:4300:12:49
name those -semimembranosus,
00:12:4900:12:52
semitendinosus.
00:13:0600:13:21
Good if psoas is up here, who else should be iliacus? Who are we missing? Biceps femoris.
00:13:2100:13:25
Yeah if you really want to get technical somebody said it's the long head of the
00:13:2500:13:40
biceps femoris, I heard somebody started. Yeah so the deep rotators would go on
00:13:4000:13:47
this side which is actually piriformis, gemellus superior and gemellus inferior,
00:13:4700:13:54
obturator internus and externus, quadratus femoris. Yeah you got it in your
00:13:5400:14:09
notes. Glute max good call. We'll also put glute medius, sartorius where does sartorius go?
00:14:0900:14:13
It does.
00:14:1900:14:22
Nice job guys.
