It's so nice that the names help to know the location and the action of the muscle. Big thank you to whoever named them!
I appreciate how you separate the muscles into groups based on similar functions, it makes it easier to study and form mental maps.
The fact that the names coincide with their location and function really makes learning these muscles much easier!
Im grateful for the names of the majority of the flexors and extensors. Finally some names that actually help us remember
The aspects of the hands and wrist are so underrated! It's crazy how many bones, tendons, and muscles are tightly packed in such as small space.
I like how you specifically showed pictures of the muscle actions which helps me understand the material more clearly.
There are so many muscles in the wrist and hand. I appreciated how you try to break down what they do by just looking at the name. It actually does make it a lot easier.
Dr. Goodin,
There were lots of muscles to learn in this video but amazingly you always manage to make it short and sweet. Thank you!
Discovering all the muscles isn't as daunting as I initially anticipated because their names are highly descriptive, aiding in understanding their locations and functions. Additionally, your illustrations overlaid on the muscle images were greatly appreciated as they provided a clearer visualization of the concepts.
Enjoying the new material that hasn't been covered in my previous anatomy and Kin classes
Breaking down the names of the muscles really helped with understanding where they're located and what their functions are. Goes to show that taking the time to understand something ends up saving more time than trying to memorize it later!
The organization of the slides was really helpful because the muscles were grouped by their names, and thus their actions, which makes memorizing them much easier.
I didn't realize how many muscles work together to move the wrist and hand. It's very interesting to me.
Learning all of the muscles isn't as overwhelming as I thought because the names are so descriptive and can help break everything down into where they are located and what they do. I also appreciated you drawing over the pictures of the muscles because this made everything more clear to visualize.
Some many muscles in such a small area, the complexity of the human body is truly amazing!
I enjoy how most of the muscles have their action in their name, it makes it easier to identify the different muscles that act on the wrist and hand.
My hand and wrist flexor and extensor muscles got a workout from taking notes on this video! Crazy that there are so many muscles working together to provide wrist and hand movements!
I see what you did there Chris!
The hand muscles have always been a little confusing to me and a lot to remember but the more and more I hear and learn about them the easier it gets. Good video!
I appreciate that when talking about a specific muscle, only that muscle was highlighted. In the forearm, the muscles are very compact together, so it was very helpful.
I like how you separated the muscles into different groups based on what they do, it helps me keep them separate in my mind as well to keep track of them all and their actions
I like how the muscles include the action and location of the body in the name! It makes it much easier to study and memorize.
This video was a nice review of all the muscles of the hand and wrist. I especially appreciate how it’s organized, very straightforward.
I really appreciate that when you described the muscles of the wrist and and fingers you had the anatomical diagram of them up to describe the line of pull with each muscle. It helps a lot to understand where the muscles are attaching to infer what their actions will be.
I like how the name can sometimes correlate with its action and the location! Great video!
I do agree the best way to understand and memorize these muscles are by understanding their names! Very helpful and easy to understand!
Good advice to not just memorize the muscle actions, but to learn how the name can help you tell what their actions are. Also, as per usual with these videos, it was very helpful to have the information organized in such a way that is straight forward.
I really like that the names of each muscle can tell you a lot, such as their action and location for the most part.
It is definitely nice how the names of the muscles give away a lot of information about them.
There are definitely a lot of muscles in the wrist and hand, but I appreciate you giving tips on how to best study and memorize them!
Thank you for painting a clear picture of how these muscles work! I think by understanding the roots in their names, it really helps to memorize their primary movement function.
I like how you connected the names of the muscles with what they do. This helps to group muscles together which is better for studying.
I had taken anatomy two years ago so these videos are a very good refresher. I think this is very helpful when having the muscles differentiate.
I liked the way that you broke down each muscle and then separating between the extensors and the flexor muscles with their actions. It was a great refresher!
I appreciated walking through the meaning of each name before showing the pictures so that I can visualize where the muscles would be and what they would do since the names are indicative of their location.
It makes sense that we need so many different muscles in our hands and wrists for fine motor movements but it is crazy to see them all and their actions.
It's definitely a nice study tip to see how most of these names help tell us the action of the muscle.
I liked how you clearly explained the location of each muscle and gave a visual of the muscles action when you were talking about each muscle. It helped me connect from what I was reading on the slide to what the actions really looked like.
I learned that breaking down the words for each muscles is a key tool in remembering the muscles with their actions!
It's very helpful that the location and function go hand in hand with the name! That is super useful in trying to memorize and understand the action, function and location.
This video really helps to clarify which muscle groups work together to produce the same actions. There's a lot to learn in this section, but this video related the muscles to each other which will help to memorize it all a bit easier.
The final portion of the video actually helped me really narrow down how to study for these muscles and their actions. Memoriziation has always been a tough thing for me to do for anatomy because of how many different names and functions that there are.
Breaking down the muscle names is helpful especially when distinguishing which muscles move what. It was also helpful that you separated the muscles by their actions and whether they move the wrist or hand, this is helpful to remember the many different muscles in this section.
It's really helpful that the names actually give a clue as to wear they cross and are located!
The breakdown of the wrist and forearm muscles is very helpful, as well as the relation between the names and the location and movement.
Its kind of crazy how many muscles are involved in wrist flexion and extension and just all of the movements of the wrist. Our body's are so intricately designed to perform so many functions, its cool to learn about.
It is so helpful that the muscles have hints in the names, such as flexor digitorum profundus --> flexor finger, deep to the superficialis.
I really enjoy how you seperate each muscle into categories based on their action, it really helps remember them. Also all your explanations of the root words based on origin was very informative.
Love the way the muscles are named, like the flexor and extensor muscles. Makes it a bit easier to memorize what actions they do!
I liked how before you dove into the actions of each muscle you broke down some of the names of the muscles which indicated some of the movements it was responsible for, it makes remembering the actions a lot easier!
Having the picture of the muscles action was helpful in studying and remembering the actions
I think that despite there being so many muscles in our hand and wrist, the names will help me determine their location and what they do which is super helpful!
I like the way you separated all the muscles and explained little clues to make it easier to know what each muscle does and where you can find it. I like that you emphasized that anything that does finger flexion does wrist flexion and anything that does finger extension also does wrist extension. Great video for studying and remembering these muscles!
The hand and wrist muscles are complex and can often get very overwhelming. The organization of the muscles, especially the finger muscles was conducive to my learning. Since I interned at a hand therapy clinic over the summer, this video on hand and wrist muscles helped relate to what I learned over the summer.
This makes the muscles i knew from anatomy and other KIN classes make a lot more sense and hearing them according to their groups was helpful
I like how you separated the extensor and flexor muscles when discussing them. I feel like it will help me remember their actions and locations better.
I've always had trouble with the muscles of the forearm that act on the wrist and hand joints, but this video has been super helpful in differentiating each one with its actions, origins, and insertions. This is definitely a video I will be coming back to for additional understanding and studying.
I really liked how for this lecture the muscles were grouped by flexor and extensor it makes it very helpful when trying to connect everything and get a good understanding.
Learning the different names within the muscle like "carpi" really helps me remember where the muscles are located!
The hand muscles are very intertwined but the images and descriptions helped me pick apart each muscle and be able to better identify with the origin and insertion of the muscles. Which also helps a lot with the actions that accompany each muscle.
These muscles in the wrist and hand I remember being the hardest for me to remember in anatomy last year so this was a good refresher and I'll definitely need to be studying them again.
Very beneficial to have the background knowledge that the muscles and their names are directly connected. This will be so helpful when memorizing the different actions of each one
I found this video interesting because it was more in-depth than the material I learned previously.I briefly went over the muscles in hand for anatomy. The information stuck with me after watching the lecture.
Being able to use my prior knowledge from anatomy definitely helps me understand all the muscle actions better. Its also very helpful that most of the names of these muscles also explain the movement they perform.
This video was really helpful because the wrist and hand section in anatomy was only briefly covered so there is a lot I do not remember about this section. This video was such a good refresher and really helped me remember things I have forgotten.
I really like your tip on memorizing the names to indicate their actions! I found it very helpful to study the muscles and where they would be located.
I got to say it is very helpful using yourself as a diagram in front of you. I will definitely do this moving forward!
I didn't realize how much muscles are involved in our wrists and hands! It's fascinating though that there's groups of muscles that handle one finger and groups of muscles that do specific actions!
I is super helpful to remember the roots of some of these anatomical terms! For example, remembering that carpi means wrist, digitorum means fingers, and pollicis means thumb.
This muscle description video was super helpful for me. It allowed me to piece together how each muscle group relates to its specific movement. for example, the flexor pollicis longus allows for flexion of the wrist as well as wrist abduction.
I really like the format of the video! It allows me to take well-formatted notes on the functions, which helps me study effectively
It was really helpful how you broke down each muscle's name and explained what it meant. For the flexor digitorum superficialis, the word digitiorum relates to digits which means fingers, and the word superficialis means superficial or on the surface.
Splitting each of the wrist and hand muscles into categories was very helpful, particularly when it came to separating flexors and extensors. For example, grouping wrist flexors on the anteromedial side now help me visualize the location and, by default, function.
This is a great refresher on A&P, however I now understand a bit more about these muscles and their actions.
There are so many muscles!!! It's nice that the names help with remembering the movements.
Back when I took anatomy, it was hard not to just memorize muscles and bones -- because there are so many in the human body. However, I like that you said knowing the name of the muscles can help us tell what their actions are. It's a huge hint that I know will help me in the future.
The various muscles were well explained and organized in a way I could follow and understand. There are a lot of muscles to recall, and this video was in depth and easy to follow which I could easily go back and study again!
I found this video really helpful as an overview of the wrist extensors especially. It is easy to overlook some with so much to know in this area, so thank you for being so specific in the actions!
The organization of this video really helped me to better understand and categorize each muscle and its actions! I appreciate the names of the muscles and their relation to their location!
This video was awesome in helping simplify all the wrist and hand muscles. There are so many muscles so it can get really overwhelming but this video made it so much easier to understand.
This was really helpful review to remember all the muscles of the wrist and hand. It is also very nice that some of the muscles are named after the action and placement of them.
In this video, Dr. Goodin goes over the muscles of the wrist and fingers and their actions. While discussing the different muscles, he parsed the long names of the muscles which really helped in my understanding of the muscles and will help in memorizing them. One main point I got from it is that all finger flexors/extensors also flex/extend the wrist as they cross the wrist. And some wrist muscles also do weak flexion or extension on the elbow joint.
I really liked in this video how you explained what certain terms meant so we can remember the muscles better. This video was very helpful in understanding the muscle actions of the fingers and wrist!
Very thankful that the key muscle groups all originate from essentially the same place. It feels so much simpler than areas pf the body like the shoulder where it feels like each muscle originates and inserts in a completely unique place
I have never heard of some of those muscles before, I also didnt know that each one of the muscles could do more than one movement. A lot to learn!
I find this video very helpful because of the breakdown of each muscles and the exact function that they produce. The muscles of the wrist and hand all have names that help describe their function which is helpful when studying.
I think knowing a framework, like you described, will be super helpful when remembering what muscle is where and what action it performs.
I like how he pointed out the relation between muscles that do finger flexion and how most also do wrist flexion
It is cool that names of the muscles correspond to their location for the most part!
This video was extremely helpful for me since this is the first time I learned most of the flexor and extensor muscles. It never occurred to me that the finger muscles are attached to wrist muscles as well and this video does an excellent job at explaining these muscles.
The wrist and hand muscles are so intricate and amazing! Loved the study tips at the end, there are a lot of small muscles to memorize.
The extensors and flexors all being on corresponding sides with the joint movement makes it a lot simpler to understand!
This was a good video for refreshing my mind about the muscles I learned from anatomy. I forgot how complicated these muscles can be!
There is a ton of muscles in the wrist and fingers that I have never even heard of! Thank you for explaining them all and adding pictures of where they are located. I find it interesting that theres the exact same muscle name and actions but one extensor version and ones flexor version.
All of these muscles were familar as we went into great depth in them during anatomy- all i could think about was cat dissection! I thought this video was super informative and I really enjoy learning these wrist and hand muscles because they seem so little but are so useful!
I liked that this video delved deeper into what we learned in BIO 1030. We learned most of these muscles; however, muscles such as the flexor pollicis longus were new!
The way yiu structure the video is very helpful and makes it 1000% easier to understand!
I found it very helpful when you explained how the names of the muscles indicate to which part of the hand its located on and it also helps me learn their actions.
A lot of the muscles sound similar! The way you broke it down so we could understand help a lot to visualize and think about!
I thought it was cool how each name tells you it’s action and location. Makes it a lot more easier to remember
This video was really helpful! I appreciated how detailed your explanations of each of the muscle actions were!
