An easy way to remember arm muscles PART 1

Dr Preddy teaching anatomy at Touro University Nevada

[TropicalChris]

If he started his own AP channel, he could make a lot of money...and I would gladly pay him. His enthusiasm and teaching ability is something I haven't seen in any other AP professor I've had...

Jim, thank you!!

when an arm muscle lecture has about a million views you know just about every med student has peeked it

[afras]

it's insane to think that most of the people who commented on this video are already doctors

[pemassey]

Dr. Preddy was sent here from someplace above us to save us and bring us understandable anatomy. But seriously, love this representing an osteopathic school!

[daveshap]

5 hours of studying, summarized in 10 mins.

I'm a medical student at Touro Nevada and the sad part is that Dr. Preddy isn't even paid to teach despite the fact that he makes anatomy so much easier... He's been coming in for years because he loves teaching and is hoping to land a part-time job here.

Three weeks of lectures didn't manage to teach me what this guy did in 10 minutes. Kudos dude.

[jengeller]

9 years later and this is still one of the best. Thank you!

[juliastrickler]

This guy is an amazing teacher! I’ve been trying to figure these muscles out for days and in ten minutes I’ll never forget them, thank you so much

[mac.health]

For my college anatomy lab, we are expected to read and memorize the diagrams presented in our lab notebook. This method of teaching anatomy and physiology is so much more interesting and effective. Thank you!!

A transcript of sorts:

Upper arm
3 muscles on the front and one on the back.
The three muscles on the front are biceps brachii, coracobrachialis and brachialis.

So the biceps brachii where does it attach to on the humerus? NOWHERE. ATTACHMENT ON THE HUMERUS, it skips the humerus entirely and attaches on the scapula and radius..
On the scapula,  the bicep brachii attaches to the coracoid process and supraglenoid tubercle down to the radial tuberosity.
This causes you to be able to turn your hand (supinate). So everybody, grab your arm like this. <Phd Preddy flexes his elbow pressing his contralateral hand to the contracted mound of his biceps> Now, I want you to stick your pinky <little finger> up as high as you can and try and relax your biceps. <surprised laughter> ...You can't. Because the biceps not only flexes your elbow and flexes your shoulder, it also is the major supinator of your elbow. It turns your hand up like that, <PhD Preddy supinates his hand i.e. turns his palm to face the ceiling >  that is supination. If you hold a bowl of soup you are supinating. <Laughter> <Phd Preddy leans backwards i.e extends from his sacrum> <more laughter> So, supine, supination, pronation supination. <hands pronate and supinate as he says the words>. So pronation,  point your thumb down, that is pronation. This is supination <supinates>, and the major supinator is the major supinator is the biceps brachii.  Now, if you make yourself a muscle <Stands in competition style flexed bicep position with contralateral hand holding contracted mound of biceps> and then turn your hand around. <Pronates wrist and whispers: "Bebe, bebe, bebe"> Do you feel it all go away? Your biceps really only work when your hand is supinated. When your hand is totally pronated your bicep doesn't work because where it attaches onto your radius is facing the wrong way. So the other muscle, the one underneath there, the brachialis, it attaches to the ulna <points to ulna>, not the radius.

At 0:33 I think he meant supraglenoid tubercle instead of supracondylar tubercle

Not sure who I love more, Dr Preddy or the person who filmed and uploaded this :) thanks all the way from Australia!

I have watched this video so many times while studying and it is SO helpful. I wish all professors were like this!

[chicken-nuggies-]

Dr Preddy, what a wonderful gift you have and a sharing with the world. I have never seen anyone teach anatomy in such a way that it flows and stays in my brain. Very grateful in Texas! Melody

[drboo]

This is the best anatomy lecturer I have ever come across!!!!
Dr Preddy, please please please make more videos! You need a YouTube
Your lessons are so exceptional!

[lilbreakdancer]

im here because of an anatomy final tomorrow
lol

[rahisme]

Believe it or not... I almost cried while watching this because I finally started understanding the muscles. Before, no matter how many times I tried, I kept forgetting which muscle is where. This prof at least did it in such a way that he throws in memory triggers... tremendous professor.

[lilliduffy]

I always come back to this video when I'm needing to refresh on the arm muscles. Currently studying for my board exam and came back to this video after 6 months. This guy is the best!!
