Erector spinae (back muscles) 

It's amazing that all this knowledge is being shared by specialists for free on RU-vid. What a time we live in! Thank you for such a great lesson.

I am a doctor who practiced for 37 years. When attending anatomy class we had cadavers that were preserved in formaldehyde. The lab room stunk and after a few hours your eyes began to burn. The use of these amazing models and professors that have a passion for teaching will turn out doctors with a higher understanding of there patients. In my practice 80% of problems seen were musculoskeletal issues and with this knowledge in the beginning of instruction is incredibly useful.

I teach anatomy and physiology and I'm drooling over the vast array of high quality anatomical models you have available

Im a PT and have recently found your videos, they're great! i am dyslexic and find i learn best from videos... you have made my learning so much easier. Thank you!!

I have been suffering from back pain for almost 10 years and I am so happy to have watched this. Utterly empowering and so well explained! Thank you so much!

you are such an amazing teacher, thank you, taking your entire anatomy course, helping me so much thank you

you are incredible at making this simple!

Is it just me , or he really looks as if he is Dr.House's son

Hi! I am Turkish and second class medicine student. Your videos are realy helpfull to me. My English is not that great but your English is as smoot as I can understand. If I said something wrong sory. I just wanted to say thanks😊

I'm a first semester DPT student and this video has helped explain the back muscles tremendously! Thank you!!!

never went to any anatomy classes and binged these videos and then got an 80 on my exam lmao thanks sam

I love the curious tone is Sam’s voice every video...it’s like he’s refreshing himself

this was equally entertaining as it was informative

Thanks so much for your videos. I am in massage therapy school and these videos really help me understand.

I'm doing a yoga teacher training right now and just discovered your channel. All very informative, made simple and explained clearly. Thank you so much. I really do appreciate your videos. There aren't many like this. Very helpful. 🙏

Thanks Sam, i was a bricklayer in my younger days and I now am learning massage .After watching this video it really points out why we get so stiff and sore ,so many layers and groups of muscles .

Thank you for some top-level anatomy classes. Couldn’t find something better. You explain and everything just makes sense now

Amazing! It´s incredible how you can explain things in a relaxed and straightforward manner. As a medical student I really enjoy watching your videos!

Studying for my Level 3 A&P exam and this has been super helpful - thank you!

This was absolutely the best anatomy lesson I've ever heard. I can't wait to listen to the next one. Thank you for sharing your vast knowledge on the back muscles. It helps that you are very funny and make learning interesting as well.

I appreciate this video a lot. A lot of the other videos that come up are for massage or exercise. I don't know what you do for a living, teacher or therapist, but you are good at explaining stuff. I like that you take the time to show us the models and even remind us what medical terminology words mean. I have a big med term book I had to get out trying to watch some other videos but you remind us as you go so we can stay on topic and not get lost. Superb job.

Great video! You are helping me understand my pain.

Thanks a lot, you really make this all make sense and easily understandable!

Omg I love you. I'm a U.S. American nursing student and I really appreciate this video. Thank you! Going to watch a bunch more of yours now!

You're amazing . Thank you 👏 we need more people like you, you take your time to explain BETTER.

I am currently a STOTT Pilates instructor and studying for my certification. You videos not only make learning fun but have provided me with the visual information I need tomato sense of the human body and it biomechanics movements. Thank you so much!! :)

I'm pumped to watch your videos on anatomy, thank you for these

i had skipped this important topic in my first year anatomy as i found it really difficult to study this complicated stuff.. but sir you made it so wonderfully understandable.. i am really in love with your videos and will definately recommend it to most of my friends :)

Prof Webster is a G. Appreciate your content, literally watch you daily 🙏

Sam Webster is Fabulous! Thank you for sharing your wealth of knowledge, we are all richer learning from you!

Yoga instructor in the USA here, your videos are incredibly helpful! Thank you for sharing.

Thanks for sharing your knowledge. A couple of hours on RU-vid and I'm now an amateur massage therapist

I've been doing drawing studies fo the back and this was a much better resource than any drawing tutorial. Thanks so much for the breakdown!

I wish I had an instructor like you...amazing work

Thank you for your videos! I'm a personal trainer and had to learn some basic bone structure. Now I want to know a lot more about our anatomy and musculature so that I can be more effective as a trainer. Your videos are extremely helpful and interesting. I like the way you make things simple to understand.

Awesome anatomy class, now I understand the superficial muscles of the back as well as the deep muscle group. Great explanation!

I have a muscle exam on Friday and this video has saved me considerable time

great video, thank you for making it! I'm looking forward to watching more of your videos :)

It's a funny new fascination watching yours and somanauts anatomy videos. they're SO moreish. I could watch them for hours. I'm a massage therapist and we did a 4hr anatomy, pathology and physiology exam with the Massage training Institute but that was all 6 years ago now and I'm seeing clients for massage most days so these videos are all invaluable help with my CPD. Thanks Sam. Also great to see you walked the Pembrokeshire Coast Path - I'm from St Davids! If you EVER have any public days in the lab sign me up, I'll be there with bells on!

You made me love anatomy…thank you very much for making those videos

Very good style, intelligent fellow. Although I'm a layman on anatomy I can say that the constant pain is simple but the relationships between the causes (back, respiration, rib cage alignment, core, hips) combine to make a complex puzzle that cause millions mental fatigue from all those zaps and jabs. So, students shouldn't begrudge the subject too much, its a heavy hitter in more ways than one! To put it in perspective: After a few years of what i used to call "oh, me back!" I corrected it to the less fashionable "aah, me hips". Discovering the possible contribution from QL made some improvement, I am now considering whether "oh, me back!" may be closer to the truth. My latest search is into the erector spinae, which has led me here. The zaps arent so bad as at least they tend to hit and its over. The trickiest element is the injection like jab received about a third of the way between the top of the iliac crest down the butt over to the side. I get this on both left and right cheeks (this may be due to two separate injuries). These jabs occur all day long, to the point where you begin to weigh up the pros and cons of most simple movements and tasks you perform throughout the day. As soon as you lean forward over a sink or a car bonnet or bend slightly to pick something up, it gives you the nip. It feels like a cord passes from the mid-back over the iliac crest and is tethered somewhere in the glutes. When you bend and start putting weight on the back, rather than the thighs, that cord then complains immediately. It is probably worse when on your knees because you are unable to take much load on your thighs. I have come across quite a few people who describe it this way, but surprisingly the solution is a much harder search.

All the best teachers entertain whilst they teach as it makes the learning fun..Great videos, thank you Sam!

You, Sir, are awesome! N a genius at explaining complicated anatomy. Thanks very, very much. Glad to have stumbled upon your videos.

great video. Just starting my sports therapy courses and this helped

I feel your passion for teaching which makes me like and enjoy anatomy.

Great videos! I love that you keep it real and relatable.

Thanks a lot sir..u r making anatomy so easy n simple to understand

Amazing lesson! Fabulous models and a wonderful presentation making it so much easier to understand. Thank you

I like the way you simplify anatomy, you are the best, thank you.

Thank you for the information and giggles! Thoroughly enjoyed and your passion!

Great explanation, thank you!

Reviewing some anatomy today and stumbled upon your great videos. Thnx so much!!!

This has helped me confirm some muscle imbalances I have been self diagnosing. Imbalance due to a deadlift accident almost 8 years ago. My erector spinae on right side of my body is extremely weak compared to opposite side. Been rehabing slowly using a glute-ham raise, superman holds, back extensions, high rep/low weight good mornings, jefferson curls. Very slow controlled eccentric/concentric. I try and do some of these exercises in a way that it will isolate my right side but it's tricky sometimes. The video is very helpful in giving my understanding and function of the group. Thanks!

Thanks for sharing your knowledge with joy.

you are brilliant i love the way you simplify things, it actually scary when i look into my lecture notes, books, not when i watch yr videos thanks very much

Wow! Thank you so much, you've explained it so it's not so intimidating. I appreciate you for making these videos.

Tu eres el mejor un gran niño grande motivado por una pasión . Thanks so much Teacher Sam

If that sounds complex, imagine when you add in the variable of exercise and dynamic loads. This is what I studied in one of my courses for exercise coaching, and it is important for safely training other people. Adding this to supplement my courses is very helpful, Thank you

Thank you for posting the video it was a huge help!

great lectures!!! Thank you professor Webster!

Really nice video, thank you for making it!

Thank you Sam.... this is a very helpful video. I am a current MT student! Perfect for visual learners

Thank you so much for this channel! I am hopelessly hooked on these videos!

I just wanted to draw vertebrae and I keep watching your videos... I think I am in love with the subject 😊 Thank you!

this is amazing, I swear your videos are the key to making it through anatomy in medical school!!

It is fascinating. I am certainly sharing with my physiotherapist...tomorrow cause now it’s late in Mauritius. Thank you very much. Best wishes

i got prolapsed disc at L3/4 about 18 months ago so i have to stretch whole bottom half of body every few hours 24/7. this helps to show what muscles are involved.

Awesome instructive video. Thanks for sharing!

Thank you so much Dr.

Thank you! I am interested in the Ilicostalis of the deep group. You nailed it. Cheers!

Love your work

My issue that brought me here is i have two knots and im curious if it truly is the erector spinae. One knot on the outter lower back muscle and one where the upper corner of the scapula and sits deep in my upper trapezious

I would have really appreciated it if you were one of my college professors. I like how you teach! Thank you for this video~

What a great video, thanks.

Mr. Webster! Your Awesome! Thank You Doc!

Great, great, great!!! 🙏 THANK YOU 😃

2:57 Serratus posterier inferior, serratus superior (boxer's muscle, helps move arm).

Keep up the good work!

i swear this can't get any clearer. Thanks for the excellent explanation.. btw, I'm here to find out why I can't extend my back.. and this helps a lot.

Awsome video. Thanks for uploading and sharing knowledge. You are amazing.

Cracking video, thanks.

Great video Sam thanks

Another great video.

That's awesome !

Thank you

great videos love the music too

Ohh it’s become very simple in a fantastic way 💛🙏🏻

I'm watching this and I have a molecular medicine exam on genetics tomorrow 😂 RIP... I just love anatomy 😂

Great help for easy understanding of anatomy stuff. And thanks for wearing that Alanya t-shirt :) greetings from Alanya

Thank you 🙏🏼

Ailecek takip ediyoruz Sam abii! Sağol! 🙏❤

You are so wonderful, thanks and much loves from Türkiye 🇹🇷🍀🧿🍀

Thank you so much

Awesome video 👏🏻

Excellent vid

Love this!

Quick question: You mentioned that, because there is a serratus posterior inferior that there must be a serratus posterior superior. Can i assume that if a muscle is named (maybe not related to its position relative to something else but in its actual name) with "inferior" or "superior" that there is a similar muscle to compliment it as given with the serratus posterior muscles? or is this one of a few cases where this happens? Thank you whether you decide answer this question or not as i'm loving these videos.

you are brilliant thank you so so much x

Thank you Doctor ... I wonder that the traversal spinal muscles is the muscles who gives the vertebral bones the chape of S isn't it ?

An10 upper extremities Final written and op coming next friday. Thank you for this Mr. Webster.
