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.

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

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!!

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

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

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

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

you are incredible at making this simple!

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!

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

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!

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

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

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😊

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 .

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

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. 🙏

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

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

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.

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

Great video! You are helping me understand my pain.

this was equally entertaining as it was informative

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

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

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

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!

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

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!

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.

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!

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

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

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

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

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

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 :)

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

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

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

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

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.

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

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

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

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

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

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

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!

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

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

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

Really nice video, thank you for making it!

Great explanation, thank you!

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

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

Thanks for sharing your knowledge with joy.

great lectures!!! Thank you professor Webster!

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

Mr. Webster! Your Awesome! Thank You Doc!

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

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.

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

having just had lumbar spinal stenosis surgically treated ( L3-5) I now understand why the recovery is accompanied by excruciating pain....cutting thru the many muscle layers to get to the inner core of the spine to remove osteophytes etc which was compressing spinal cord. recovery slow but steady.

Awesome instructive video. Thanks for sharing!

What exercise can I do to relief the pain of the Erector spinae?

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

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

Hi, Great video. I have a question that has been bugging me for a while. Hope you have the time to answer @samwebster I see the lats are covering the erector spinae muscles in the lower back area. Why then are the erector spinae muscles so prevalent in the lower back area?

Great, great, great!!! 🙏 THANK YOU 😃

I'm really interested by your videos, and could you please recommend some books or apps regarding to muscle and especially the methods to identify problematic muscles that hurts in a specific movement or posture. I recently hurt my back muscle and find it difficult to identify if it's erector spinae muscle or other back muscles.

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 ?

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

Keep up the good work!

What a great video, thanks.

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

Love your work

great info! any recommendations on where to get the mini muscular model you used in this video?

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

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

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

Thank you so much Dr.

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

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

Cracking video, thanks.

That's awesome !

Another great video.

Sam please how to fix neurhogenic thoracic outlet due to weakness one on side of body snd compensation on the right , should thr lower back muscles of the left weak dide lats go up be activated and strengthen traps etc but scalene last please help with what order or seqience if activation on weaker side

Great video Sam thanks

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

Love this!

thank you, Sam! Iºm not a professional at all. Iºm trying to find a muscle, or muscles that could widen (? make it wider) the spaces between the vertebraes is there specific ones to do that? To strech the spine upwards? Would that be the ªtransversal spinal musclesª youºve mentioned in this video? would you have specific videos on the muscles I need to know?

God, I love this human.

Awesome video 👏🏻

great videos love the music too

When you talk about the erector spinae muscles, would a good body weight exercise for these group of musclea be just bending over and coming back up?
