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!

@willhopkins4197 2 года назад

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

@colewaclawski540 3 года назад

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

@caitlindonaldson3681 2 года назад

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!

@cassandraalviz1675 4 года назад

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

@DrJacobGoodin 4 года назад

He's a good little dude!

@maddie.bonadurer 5 месяцев назад

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.

@madelinehernandez8838 Год назад

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!

@kaileegross7476 2 года назад

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!

@devinito7660 Год назад

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

@evakoutelieris9550 Год назад

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

@kennethvogan4708 2 года назад

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

@emmasanchez5975 3 года назад

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.

@user-fw7lg1ve8g 9 месяцев назад

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!

@oliviadyck510 4 года назад

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 4 года назад

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!

@nicolelewis3329 2 года назад

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

@makaylageorge9978 2 года назад

I liked the acronym SITS to help remember the rotator cuff muscles!

@ameliabrock 5 месяцев назад

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

@laurenmayheww 10 месяцев назад

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.

@tianguyen3897 2 года назад

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!!

@hannahkefalas9995 3 года назад

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 10 месяцев назад

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

@julianasum8481 Год назад

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

@PLNUstephaniekhin 5 месяцев назад

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

@sydneycheng2264 Год назад

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

@birileon3559 Год назад

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

@chaseplott3199 Год назад

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

@makaylanorwood1713 2 года назад

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

@alannabergherm8046 2 года назад

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

@emmafrazier204 Год назад

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!!

@user-dy4gb9tx3h 10 месяцев назад

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

@peytonyoshida7500 2 года назад

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

@natalievandell Год назад

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!

@kieranmccarty1039 Год назад

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!

@coreycollier973 3 года назад

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

@isabellecousineau302 2 года назад

I found the SITS acronym to be super helpful.

@chynnakifer1218 2 года назад

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!

@zanedirenzo5820 Год назад

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

@Monaz185 10 месяцев назад

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

@faithsanchez7000 3 года назад

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.

@oliviashaw3148 Год назад

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.

@gaelruiz488 10 месяцев назад

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.

@kylesands9693 10 месяцев назад

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!

@hannahchacon9621 Год назад

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!

@mollytucker567 10 месяцев назад

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.

@gracehalcomb 10 месяцев назад

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.

@user-kq7lc4xr4n 5 месяцев назад

I appreciate the shown movements as I learn better visually.

@ilsechavez 2 года назад

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.

@sofiawallauch1078 Год назад

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.

@laurenhufault367 Год назад

Thanks for the SITS acronym, that will make it a lot easier to remember the rotator cuff muscles! Also, your son is adorable!

@alexiaharlow8565 10 месяцев назад

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.

@ClaireStone-jq4wg 5 месяцев назад

Loved the short feature we got there in the beginning!

@madelinejewelnebril2871 10 месяцев назад

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

@gisellemedina4597 Год назад

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

@AlexisRomo001 5 месяцев назад

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

@morganrolleri9198 Год назад

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!

@baileywilliams2821 Год назад

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-rd2fj3lw6m 5 месяцев назад

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.

@shannontingleff 5 месяцев назад

your acronym SITS really helps me remember the rotator cuff muscles

@katemalicdem273 2 года назад

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.

@victoriatilden4053 2 года назад

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.

@matthewdato 10 месяцев назад

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!

@avajgallo Год назад

I appreciate the SITS acronym! This will definitely be helpful in the future.

@aliciahernandez00233 10 месяцев назад

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

@jakebergherm2786 10 месяцев назад

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!

@dimitricarrion105 2 года назад

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

@tylerbarnhill78 2 года назад

I liked the graphs that you kept showing because it gave a visual image

@makennakaczmarczyk7563 Год назад

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.

@oliviawong7538 10 месяцев назад

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.

@lucamarin8565 Год назад

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

@mackenziehustead4037 Год назад

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.

@KatelinNeff 10 месяцев назад

Great video breaking down the muscles that move the shoulder.

@miadenava585 10 месяцев назад

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!

@emilyannhively 5 месяцев назад

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

@rozalynnlarson8835 2 года назад

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

@jessedemuth4289 Год назад

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.

@user-fc3rt5mq8x 10 месяцев назад

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!

@ltapia0022 10 месяцев назад

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.

@thelmasepulveda4481 Год назад

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

@tsalazar0020 2 года назад

I liked the acronyms, highlighting, and descriptions. Was all very helpful in learning the muscle actions!

@jessiesophie 2 года назад

This video was extremely helpful in reviewing all the muscles and how many actions the muscles can do.

@catherinegallegos2918 Год назад

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)!

@abartsch0022 10 месяцев назад

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.

@KylanJohnson-hu1lr 10 месяцев назад

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.

@alexisnoelle1220 2 года назад

I loved seeing Jack in this video! Also really like the SITS acronym and think it will be very helpful in memorization!

@jonathanrobyn2450 3 года назад

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.

@MaryErickson335 10 месяцев назад

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

@isabellarondon235 10 месяцев назад

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.

@soleilgraham3042 Год назад

Hey Dr. Goodin! It was helpful to palpate myself while doing the shoulder joint muscle actions. I could see this skill being super useful on a future iRAT. Also I'm so happy you didn't edit your son coming into the room out of the video. It was so cute!

@hannahlien5137 Год назад

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.

@ericagurr9008 3 года назад

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 3 года назад

Glad it was helpful Erica!

@user-fj4of3pi1l 10 месяцев назад

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.

@joyshang5670 Год назад

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

@Chasebowen23 5 месяцев назад

the acronym SITS was a helpful technique that i have not heard of before!

@emilymerkes8707 10 месяцев назад

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.

@evaozimec 2 года назад

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 :)

@everoche3754 Год назад

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.

@brysonhashimoto2878 Год назад

It is very interesting how there are so many muscles within the shoulder joint and how each help with similar movements of the shoulder.

@michaelfischer3691 2 года назад

Thanks for drawing over the diagrams to show the different fibers!

@jadenrea1109 Год назад

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

@analisabaez-pelayo5914 Год назад

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!
