Nerves to shoulder muscles

There are a number of important muscles in the shoulder region that move the scapula or the humerus. These muscles have a number of similarly important nerves innervating them, mostly from the very nearby brachial plexus.
Let's look at 6 of the most important nerves and 2 pairs of smaller nerves:
Accessory nerve
Axillary nerve
Suprascapular nerve
Dorsal scapular nerve
Thoracodorsal nerve
Long thoracic nerve
Pectoral nerves
Subscapular nerves
It's going to take a while!

Shoutout from a Brazilian med student, studying in Argentina and having the most of it with your videos! Thank you very much!

[@CokeandSnickersA7X]

Great videos! You make studying for the anatomy final much more manageable, thank you for that.

[@JamalmohamedHassan-nj6kl]

what a great teacher Sam. you just concluded my whole week lecture about shoulder joint muscles in just a few minutes but with profound effect on my understanding. Allow me to make a summary on this comment section just for the sake of learning and to those who want to read through different ways. spinal accessory nerve- trapezius muscle axillary nerve- deltoid muscle supra scapula nerve- supra and infra spinata muscle dorsal scapular nerve- rhomboid major/minor muscle thoracodorso nerve- latissimus dorsi muscle long thoracic nerve- serreteus muscle subscapular nerve- upper/lower subscapular nerve- subscapular muscle pectoral nerve- medial/lateral nerve-pectoralis major and minor muscle

[@pontericky3506]

Thank you for your videos. I'm about to start my physiotherapy degree and you've helped me feel more confident about breaking down the anatomy of some of the major joints etc. Really appreciated

[@hayatmaleeha]

Bless ya sir ! You've really made my study so much easier !! 🤧❤️ Had been struggling with all this and you've helped me understand it in such a better way ! 🌸🥺

[@gulcenuryigit7681]

When i need to study anatomy, i keep coming back to your videos sir. Thank you very much

[@GodOfUninteresting]

You have no idea how much i wished this man was my actual Lecturer! Learnt so much in such a fun way. Thanks

[@AyeshMedic]

Amazing lecture. I got all of it in my brains. Thanks for this Awesome Lecture. I have an exam and you're a blessing.

[@fatimaghasemi7444]

Dr.webster thanks so much for your wonderful teaching ....since I've been watching your videos ... I understood that anatomy is one of the beautiful sciences that human should learn...I'm Iranian & medical student

[@acacianorison]

Dr Sam your approach in these learning videos is wonderfull and full of joy👌

[@jamalshah2376]

God Blessed you.....The most amazing Lectures of Anatomy i have ever seen .....Thnks sir

[@thespartanathlete5021]

Thank you very much for these videos! Really helps me for my physiotherapy studies. Greeting from Slovakia!

[@spirit-of-joy3808]

Very informative video! You've made the nerves easier for me to understand, Thank you very much!

[@LiveTaoism]

Although don't know most of the nerve names, I understand what you were saying fairly clearly and even tried to connect pain with areas to massage according to where the nerves came from. I however won't mix it with my meridian knowledge which may suggest headache to be treated via feet. or lower backpain via hands. Initially learning this as I had difficulties locating acupoints along the spine(feeling too many gaps than it actually has). I found this channel and Autonomy Zone quite helpful. Many thanks.

[@zore4686]

i cant thank you enough! you're a life savour!

[@mourilshah2054]

Excellent video,I was struggling way too much with these especially nerves but you’ve gelled it quite well

[@shashidutt5012]

I love your videos. You are comedienne, very knowledgable comedienne!

[@accouchesousx4822]

A great thank you from France, Sam. Your videos are really good.

[@liliaaaaaaaa]

Thank you very much, well explained and logically described, therefore easy to understand for not just an academic needing to swot for exams but also a lay person such as myself. I had an accident in July 4 months ago, but since I had fractures elsewhere (maxilofacial) no attention was given to my shoulder / arm injury since it was just all lumped together as a "soft tissue injury". 4 months down the line I'm still in agony, waking up from agonising pain in the early hours of the morning, and have already offended one doctor attempting to prod me, telling him I didn't need his physiotherapy advice. Watching this video has now helped me understand I have a shoulder compression injury to the bracial nerve complex in particular to the accessory nerve affecting my trapezius muscle, causing agonising nerve pain, no prodding or physiotherapy will help in the short term and I am better leaving it alone to heal naturally without complication. I've arranged another telephone appointment with another doctor to get some more appropriate painkiller meds. Thank you for your informative video. ✌🙏

[@SUZABQ]

[@kukuhindustanigamer3663]

Can you please do a few videos on embryology? I've been watching your anatomy videos and they are great.. a few videos with embryology models would help a lot..

[@SamWebster]

I have written a textbook (Embryology at a Glance) and have a few podcasts (www.samwebster.net) but I don't have many embryology models. Because embryos change with time it's difficult to show with models. Cheers!

[@kukuhindustanigamer3663]

I'd get the textbook.. thanks!

Wondering why the vagus nerve is not mentioned. Thanks.

[@Fatima-jc4hm]

Sometimes I forget that I'm here to learn anatomy 🤭😶‍🌫 You're an amazing teacher by the way :E

[@nabakhshetyan]

Great videos! The only thing that I think is very important and missing in your videos are some discussions from evolutionary standpoint, so that we can understand much better not only a particular structure, but also the purpose of that structure

[@mosesnsamba2746]

Hi Doc. How to repair one when its damaged. Any remedy to that especially the ones that runs from the back through armpit and down the hand.

[@mobinash8599]

Thank uuuu💕💕💕💕💕

[@pnv2151]

What is the nerve supply for supraspinatus?

[@troymatthews3287]

I get brachialis and serrated edge mixed up because the brachialis makes the bicep look bigger and so as a result I think of being shredded so then I call it the wrong muscle. It's not a knowledge thing it's just a mixing up the words thing.

[@matthewcasilli4340]

Hi Sam, What qualifications do you have in order to teach anatomy? I’m just curious. Thanks!

[@SamWebster]

I've got a BSc in Anatomical Science and a PhD in molecular, cell and developmental biology, but there aren't many anatomy teachers in the UK. We might be looking for an someone to teach anatomy later this year that has some human anatomy experience and enthusiasm for teaching, so requirements are variable.

[@matthewcasilli4340]

Awesome! Thanks for sharing Sam

[@prathibarani5442]

Hello sam, I have pulling sensation nd tightness in the medial border of scapula with weakness of upper back muscles and arm. I dont have shoulder pain.if there is nerve damage in any of the nerves supporting the upper back muscles,how to test nd what is the approach to treat it
