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!
I love how jack whispers to try to be respectful of your lecture!!! So adorable!
He's a good little dude!
Little Jack was a funny interaction. "Please go because now I have to edit this". Glad you kept it in the video
Showing us the motions is actually really helpful. Looking at diagrams doesn't always explain everything.
I loved the part where your son came in and he looked so excited!! I also really enjoy how you highlight the muscles being used for specific actions!
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.
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.
Understanding the functions and pull of each individual muscle often trips me up. The highlighted segments on the images were helpful in connecting your verbal lecture with a visual representation. I would like for Jack to join us in every class. He's so sweet!
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
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!
The detail in this video (and like everyone is mentioning--the acronym SITS) all really help to remember the detail of the rotator cuff.
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!
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!
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.
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
I think it’s fascinating how muscles related to the back and shoulder work together to influence a lot of shared movements.
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!
With the muscle action videos, doing the movements while you explain them is really the best learning tool I have found.
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.
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.
Muscle actions are one of the most important things to know. This video was very clear in breaking down each action clearly and concisely.
Outlining what the muscles do on the images helps a lot especially when talking about how the fibers work together!
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!!
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.
SITS acronym was a great tool to remember those muscles. Its amazing how many different components contribute to our shoulder joints.
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.
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
I laughed so hard when Jack popped in! He is so adorable. This video was a much needed review of all of these muscles.
I loved when Jack walked in haha, really brings back to covid memories from having to do everything at home!
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.
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
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.
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.
I liked the acronym SITS to help remember the rotator cuff muscles!
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.
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.
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.
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!
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.
Talking about the actions of muscle fibers during each component of each muscle action was a breakthrough for myself!
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
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!!
The numerous amount of movements mentioned blows my mind. I really learned a lot from this video!
I really like how you highlight the muscles that are being used for a certain action. It really helps me learn better.
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!
I loved Jack's cameo!! The SITS acronym is going to be really helpful when palpating and studying these muscles.
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.
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.
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!
Definitely liked each muscle breakdown, makes it easier to understand as it is broken down into "parts" of each muscle movement as a whole.
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!
Thank you Dr. Goodin. You bring the master list to life!
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!
The way that you described the different fibers was very helpful to keep them straight.
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.
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!
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!
I loved the part when Jack came in, he is so cute! I've remembered the SITS acronym since high school anatomy, it is really helpful.
Your rotator cuff muscle acronym "SITS" was really helpful. I have trouble with memorizing those muscles so that'll really help.
This video was well organized in a way so I could easily follow where we were and which muscles we were discussing. I have a better understanding of the shoulder joint muscles and what they do for movement. Thanks!
Thank you for the reminder of the SITS acronym! It comes in handy when remembering the rotator cuff muscles.
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.
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
I found the SITS acronym to be super helpful.
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!
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!
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.
SITS acronym was helpful. And going through the muscles was very helpful. Jack seems awesome.
Thanks for the SITS acronym, that will make it a lot easier to remember the rotator cuff muscles! Also, your son is adorable!
It's awesome how much is involved with the movement of the shoulder! I liked how this was organized and the visuals you provided as it made it more interesting and easier to understand! Also, I thought your son walking in during the video was funny and was a just a wholesome moment!
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!
Glad it was helpful Erica!
I appreciate the shown movements as I learn better visually.
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.
Loved the short feature we got there in the beginning!
This was a good refresher for me. Grouping the muscles helps me remember the location and the actions.
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.
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.
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.
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.
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.
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)!
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.
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.
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!
I really like how you gave examples and showed us the movements. This really helped me visualize the actions of the muscles. I also liked how you told us about exercises to strengthen the muscles.
The SITS acronym of the rotator cuff muscles helped me so much in anatomy last year.
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.
Thank you for giving us an acronym for the rotator cuff muscles, I find them to be helpful in memorizing.I liked that you explained where each muscle connected and further explained how they would contract/stretch to pull on the fibers and move the humerus!
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.
I appreciated learning about the the muscle actions which helped me better understand how the muscles help move the shoulder joint.
It's so helpful to know the origin and insertion of each muscle to know its actions
The layout of your teaching is well organized, and it helps my brain visualize certain muscles better. Also, hearing about covid is giving me horrible flashbacks from being stuck in my house haha!
Aw, I loved seeing Jack! This video has a lot of info but I found it helpful how you highlight the muscles when you are talking about their action. That helps focus my brain and picture it on myself.
your acronym SITS really helps me remember the rotator cuff muscles
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
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.
I find it fascinating how many muscles we have and it can be really hard to comprehend this material but I enjoy the way you explain their functions and make it very fun to learn :)
Didn't realize the different parts of all these specific muscles performed such opposing actions, in anatomy and phis we only really mentioned the different actions of the different parts of the trapezius
I remember learning about the rotator cuff muscles, but your video provided a more in-depth analysis. It is also helpful to picture the direction of muscle fibers and how they relate to different movements.
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.
Thank you for showing us the movements as you talk about them! As a visual learner this definitely helps me to understand the differences between each movement because it can get a little confusing! The SITS acronym was also very helpful to remember the muscles of the rotator cuff! Drawing out the lines of pull also helped to show why each muscle does each movement!
