Shoulder Joint Muscle Actions

[@trevortonge5687]

I really appreciate how Dr. Goodin said he was going to have to edit out the part where his son interrupts what he was saying, but instead he left it in. So wholesome!

[@cassandraalviz1675]

I love how jack whispers to try to be respectful of your lecture!!! So adorable!

[@DrJacobGoodin]

He's a good little dude!

[@colewaclawski540]

Little Jack was a funny interaction. "Please go because now I have to edit this". Glad you kept it in the video

[@willhopkins4197]

Showing us the motions is actually really helpful. Looking at diagrams doesn't always explain everything.

[@maddie.bonadurer]

Love the little cameo from Jack. I think seeing these diagrams of each individual muscle helps when trying to visualize the action they do versus seeing all of the muscles at once.

[@emmasanchez5975]

The SITS acronym really helped me to memorize those muscles. Also Jack walking in was really cute and shows how working at home is haha.

[@oliviadyck510]

Aww I loved seeing jack! I have the same struggle- I am currently living back with my parents until I can go back to San Diego, and we are a foster family. I have a 3 year old foster brother who only ever wants to play and scream, making it super hard to get studying done here! But I love him lots and hes making quarantine more fun- kids are just the best!

[@DrJacobGoodin]

I love that Olivia! What an amazing way to for a family to share their love and welcome in someone who is truly in the “vulnerable” category in every way. I bet your a great big sister to the little guy!

[@madelinehernandez8838]

I think there needs to be more Jack content, so adorable! I feel like I learned a lot of new things about the different fibers and how they work. Thank you!

[@nicolelewis3329]

The detail in this video (and like everyone is mentioning--the acronym SITS) all really help to remember the detail of the rotator cuff.

[@devinito7660]

With the muscle action videos, doing the movements while you explain them is really the best learning tool I have found.

[@laurenmayheww]

I appreciate the acronym you gave us to remember the rotator cuff muscles. No wonder why conditioning for swimmers on dry land is so important in order to achieve stability while performing in large ranges of motion during each stroke in the water.

[@ameliabrock]

I appreciate how you highlighted the importance of proper technique and conditioning to prevent injuries, especially with the rotator cuff muscles, those seem super easy to throw out of wack

[@chaseplott3199]

SITS acronym was a great tool to remember those muscles. Its amazing how many different components contribute to our shoulder joints.

[@moirabryson5042]

I really like how the pictures shown for each muscle has the muscle highlighted and shown so that we can see it clearly and I also like how you have all the muscles actions listed out for us to see!

[@hannahkefalas9995]

I laughed so hard when Jack popped in! He is so adorable. This video was a much needed review of all of these muscles.

[@Jerel_Q]

I think it’s fascinating how muscles related to the back and shoulder work together to influence a lot of shared movements.

[@user-fw7lg1ve8g]

I have watched tons of your videos, they are extremely helpful. I think one of my favorite parts has been when your boy walked in to talk to you. That made you human to me! lol. its been a struggle being a mom in school, so i appreciated how you interacted with him and then got soft at the end and said "I love you" as he was walking out. thank you for leaving that in the video. it was needed for me!

[@julianasum8481]

Muscle actions are one of the most important things to know. This video was very clear in breaking down each action clearly and concisely.

[@evakoutelieris9550]

I loved when Jack walked in haha, really brings back to covid memories from having to do everything at home!

[@sydneycheng2264]

It's always good to have a reminder of how important our rotator cuff muscles are - and how good technique with exercise and sports are vital to prevent injury

[@katemalicdem273]

When Dr. Goodin brought up taking care of your rotator cuff, it made me be more concerned about my physical body. It is good to know that I'm realizing now that our body is truly underrated and we don't realize how complex our body really is. Learning about the connection between bones, muscles, and joints gave me a perspective to appreciate it more.

[@faithsanchez7000]

The arrows depicting the various movements of the muscles is so incredibly helpful! Sometimes hearing all these anatomical terms can be overwhelming, so being able to visualize the movement in order to perform the actions is very helpful.

[@makaylanorwood1713]

I really like how you highlight the muscles that are being used for a certain action. It really helps me learn better.

[@kennethvogan4708]

Thank you Dr. Goodin. You bring the master list to life!

[@PLNUstephaniekhin]

The numerous amount of movements mentioned blows my mind. I really learned a lot from this video!

[@gracehalcomb]

I loved the images that were included because they only highlighted the specific muscle you were referring to. There are so many muscles in the shoulder joint, so this made it easier to visualize the individual muscles. I also really liked that you were able to draw arrows over them when talking about the movements.

[@coreycollier973]

Talking about the actions of muscle fibers during each component of each muscle action was a breakthrough for myself!

[@NoelleDarquea]

This video is the first time I have ever heard about the Coracobrachialis Muscle and now, with this video, I am able to describe the importance of it, like shoulder flexion, adduction and horizontal adduction and why it is crucial for our body during muscular movement

[@gaelruiz488]

There is so much to take in about the shoulder and the many muscles each having their distinct movements. Thank you for breaking it down one by one and visually doing some movements to help us remember the way they react.

[@user-fj4of3pi1l]

I had no idea how many back and shoulder muscles have the same kind of movements. I was excited to see the rotator cuff on this video because I currently know someone who is dealing with a torn rotator cuff and understanding more deeply the muscles connection and joints will help me help her.

[@alexiaharlow8565]

I really enjoyed going through all these muscles that help the shoulder move! I really want my 'specialty' when I become a PT to be shoulders, so I think it is super important to understand all the muscles that help the shoulder girdle move properly. It is important to know all aspects of the shoulder to diagnose and rehab but knowing the supporting muscles and how to strengthen them are the biggest part of rehab.

[@baileywilliams2821]

As an athlete its so cool to learn about these muscles and how they are working simultaneously to make something like an arm swing possible

[@user-dy4gb9tx3h]

I appreciate you teaching about the lines of pull and the muscle contractions. I also appreciate the visuals because it makes it a lot easy to learn and understand the muscle actions of the shoulder joint

[@makennakaczmarczyk7563]

Although they're small, I think the rotator cuff muscles are a really important muscle group to learn about, so this video was a great reminder of what they do. The pictures also helped me better visualize their origins and insertions.

[@jakebergherm2786]

It is crazy how many different movements that each of these muscles do! It even varies based on where the joint is before the muscle begins to pull on its insertion point!

[@mollytucker567]

This video really helped me better understand how the movements work due to getting to visualize them. It is crazy how much our shoulder joint muscles can do.

[@birileon3559]

Definitely liked each muscle breakdown, makes it easier to understand as it is broken down into "parts" of each muscle movement as a whole.

[@jessedemuth4289]

The shoulder is probably the most fun structure to learn the muscles for. There are so many movements that can be performed and so many muscles that aid in stabilizing the glenohumeral joint.

[@emmafrazier204]

I really enjoyed how you went deeply into each muscles and shared pictures to help everyone watching understand better. Also, the part where you son came in was adorable, he seemed so happy!!

[@tianguyen3897]

This video definitely covered a lot of content, but seeing your son made it ALL BETTER. Your tip of doing the motions as you talked through the slides was very helpful. Thank you!!

[@user-rd2fj3lw6m]

This video served as a fantastic refresher on the functions of the rotator cuff muscles, which are a particularly important muscle group to understand despite their modest size. I could also see their insertions and origins more clearly thanks to the images.

[@kieranmccarty1039]

It is amazing how many shoulder movements there are and how they work. This is definitely a video I will be looking over multiple times!

[@Monaz185]

Outlining what the muscles do on the images helps a lot especially when talking about how the fibers work together!

[@peytonyoshida7500]

The way that you described the different fibers was very helpful to keep them straight.

[@kylesands9693]

So much goes into the shoulder, great job breaking it all down for us to understand. Cool to see all the small different rotator cuff muscles discussed!

[@oliviashaw3148]

Very informative. I liked how you told us the muscle, showed us where it is located, and then explained their actions. It was really helpful that you did this same layout for each muscle, makes it way clearer/easier to learn.

[@chynnakifer1218]

It’s funny that you said the the coracobrachialis does get a lot of love! Your son coming in was the essences of what quarantine was on zoom!

[@emilymerkes8707]

In this video, Dr. Goodin goes over the muscles of the shoulder joint. Most originate on the scapula and clavicle. This includes the deltoid, coracobrachialis, teres major and rotator cuff muscles as well as the latissimus dorsi and pectoralis major. It helped a lot to see diagrams of insertions and origins because that helped me visualize the muscles' actions.

[@sofiawallauch1078]

It was super helpful that there were individual diagrams of each rotator cuff muscle. It really helped be visualize each muscle and what their corresponding actions would be.

[@hannahchacon9621]

Palpating myself and following along with the video was definitely helpful to help memorize the movements. As a visual learner seeing you perform the movements was very helpful. Your son is so adorable!

[@oliviawong7538]

It is super cool to see all of the different muscles and how the different type of fibers do different actions and how that affects other groups. I really like how in depth this video is, I have never gone this deep into these different muscles.

[@alannabergherm8046]

I loved Jack's cameo!! The SITS acronym is going to be really helpful when palpating and studying these muscles.

[@nathanfernandez1568]

After watching this lecture video on the muscle actions of the shoulder joint, I found it extremely interesting how versatile the pectoralis major muscle is! Especially how the lower muscle fibers are able to extend in a flexed position!

[@elisemoreno6252]

As someone who memorizes things best when I use acronyms, I really liked the use of SITS for the rotator cuff muscles. Sometimes it's easy to mix them up, especially when learning so many other muscles, so it really does help.

[@KelseyWilliams-vr8kn]

As a former swimmer, I definitely think rotator cuff injuries are the most common in swim. If you grew up swimming, you definitely knew at least 1 person who had injured theirs (or you yourself did!). Also, loved seeing the little guest star of this video!

[@madelinejewelnebril2871]

Thank you for the reminder of the SITS acronym! It comes in handy when remembering the rotator cuff muscles.

[@ericagurr9008]

I thought this lecture was a great review of the shoulder muscles and I appreciate your advice to practice finding and using these muscles on ourselves and each other!

[@DrJacobGoodin]

Glad it was helpful Erica!

[@hannahlien5137]

Reviewing the muscles in a deep-dive was helpful because they all have so many actions! The SITS acronym helps to remember the rotator cuff muscles easily.

[@jamarmack9626]

Learning the SITS acronym really helped me with being able to remember those muscles and the arrows that were used really helped me with recognizing the muscle movements

[@everoche3754]

I always love learning about the rotator cuff muscles. I learned that even though they are small and may not seem very relevant, they play a huge role in sports and prevention of injury.

[@hunterlong2817]

It is cool to watch how a single muscle can extend over the whole joint and do so many different actions, like the deltoid muscle having three fibers and performing abduction, flexion, etc. The different acronyms were also helpful in memorizing the rotator cuff muscles.

[@lucamarin8565]

The SITS acronym of the rotator cuff muscles helped me so much in anatomy last year.

[@user-ft4jt4zm7u]

Highlighting the muscle use for certain actions was very helpful

[@isabellecousineau302]

I found the SITS acronym to be super helpful.

[@jadenrea1109]

regarding certain muscles like the deltoid, it's super neat that muscle fibers perform specific actions based on their location within the muscle.

[@abartsch0022]

I liked how you focused on each muscles individually so that way we can really see what they do. I like the kid's cameo. That is crazy how the pectoralis major can do both abduction and adduction. I like the acronym you gave, it's very helpful.

[@maggiewolf5692]

I think a lot of these rotator cuff muscles could get confusing when thinking about all of the movements that they do the acronym SITS is super helpful. Super cool to learn about more in depth

[@mackenziehustead4037]

This was a great overview of all of the actions of the shoulder joint muscles. It's a lot, so I will definitely be coming back here to review and see it visually multiple times because that is how I learn best.

[@zanedirenzo5820]

SITS acronym was helpful. And going through the muscles was very helpful. Jack seems awesome.

[@cecevisque408]

Your pneumonic about the Supraspinatus, Infraspinatus, Teres Minor, Subscapularis (SPITS) was really helpful and a great tip to remember! I found it really fascinating how the muscles on our shoulders function and it gives me a better understanding of how to take care of it better.

[@rozalynnlarson8835]

It's so helpful to know the origin and insertion of each muscle to know its actions

[@EmileeWoods-ho3qm]

The Teres Major is a muscle that I typically overlook and it's so interesting to see the variety of functions that it has, like extension, internal rotation and adduction.

[@wyattcarlson7504]

When you were explaining the functions of the pec major muscles I liked that you went through and listed different movements for the different sections of the muscles. Like what activates the lower pec strands versus the upper pectoral muscle strands.

[@dereklinck2672]

I am personally partial to a good acronym from my time in the Marine Corps, so the SITS acronym I think is going to stick with me and be very helpful when recalling the numerous movements of the muscles of the shoulder joint and shoulder girdle.

[@MaryErickson335]

I liked how when you talked about the movements of the muscles, you also showed the movements giving a good visual. It also helped me to follow along better and do the movements myself and feel the muscles. I also liked your son's little debut I'm glad you didn't edit it out

[@catherinegallegos2918]

I didn't realize that there were so many muscles that abduct, adduct, flex, and extends the shoulder. This video was really good at highlighting all of those muscles and how it moves. Also, I thought it was really cute that your son was in the video (even if it wasn't intentionally)!

[@torilucht5871]

This was a great overview of the shoulder joint muscles and I appreciated how you went to explain the movement caused by each muscle that is part of the rotator cuff.

[@user-sd3sv7uq7f]

The numnbr of actions of every muscle is incredible, it has always been a challenge to memorize but muscles are so great

[@aliciahernandez00233]

This was a good refresher for me. Grouping the muscles helps me remember the location and the actions.

[@AlexisRomo001]

Your rotator cuff muscle acronym "SITS" was really helpful. I have trouble with memorizing those muscles so that'll really help.

[@miadenava585]

The SITS acronym is super helpful in memorizing the rotator cuff muscles. I liked how you went deeper into the many different actions that are performed by each muscle. Thank you for this informative video!

[@laurenhan0023]

This video was really helpful to determine the main muscles in the shoulder and it makes sense why shoulder injuries are so common! Especially when exercising and doing and over head shoulder work, it is important to stretch and not use more weight than you are capable of to avoid rotator cuff injuries.

[@morganrolleri9198]

Jack was so sweet!! Having the lines of pull explained was very helpful. I feel now that I know that I will have an easier time understanding the joints. Thank you!

[@thelmasepulveda4481]

I really liked the acronym for the rotator cuff muscles! Thank you for really explaining in detail the movements of each muscles.

[@shannontingleff]

your acronym SITS really helps me remember the rotator cuff muscles

[@user-kq7lc4xr4n]

I appreciate the shown movements as I learn better visually.

[@dylanjames8927]

I thought it was fun to learn about where the muscles origins and insersions are. There are so many muscles that have so many different movements, it's crazy to think of how they all work together without us even thinking about it.

[@jupshaw]

I love learning about the SITS rotator cuff muscles because of how important they are in stabilizing the shoulder, especially in overhead movements. For instance, volleyball players need strength in this group of muscles in order to have healthy shoulders.

[@jackfischer2553]

I haven been surfing for a decade and my right shoulder has been a big problem. It has been very interesting to learn about how the muscles of the shoulder work together and some of the key problem points.

[@joyshang5670]

I appreciated learning about the the muscle actions which helped me better understand how the muscles help move the shoulder joint.

[@gisellemedina4597]

There are definitely a lot of muscles, but seeing how they all play a role with their movements is very interesting.

[@timnoveda4004]

The part where you talked about the upper and lower fibers in the pectoralis major was very informative. It helped me better visualize the actions of the muscles/fibers involved.

[@jonathanrobyn2450]

Thanks Dr. Goodin! It was helpful to have the lines of pull explained. I feel like memorizing the lines of pull is the easiest way to understand the joint on a deep level.

[@isabellarondon235]

Very educational. I enjoyed how you described the muscle, shown out where it was, and then described what it did. It was quite useful that you used the same layout for each muscle; it makes the information much clearer and simpler to understand.

[@dimitricarrion105]

I liked the visual diagrams along with you explaining the functions and examples of movements for each muscle.

[@emilyannhively]

The SITS acronym is very helpful to remember the order of the rotator cuff muscles!!

[@macynunez4455]

Learning about these movements has always been so interesting to me. The SITS acronym has always been an awesome one to help me remember the rotator cuffs. I like the emphasis on proper technique and injury prevention!

[@BrianaReynoso]

im excited to do my own palpitation video this week because i know it will not only help me memorize these actions but help me really learn exactly what is happening! The images were very helpful!

[@ltapia0022]

It is super helpful with the tips you give us for memorization such as the acronym SITS. When taking exams and quizzes tricks like this help me remember key points. Your son also looked so happy coming in to see you. It was an adorable moment I am glad you didn't edit out.

[@celinegriffin3244]

This video was very helpful because the way you explained each movement of the muscle of the shoulder joint with their pictures and doing it at the same time made it easy to go through the motion. I liked how you had an acronym for the rotator cuff muscle
