Dr. Jacob Goodin is a professor of kinesiology at Point Loma Nazarene University (PLNU), and holds a PhD in Sport Physiology and Performance from East Tennessee State University. He has over a decade of experience as a strength and conditioning coach and sport scientist from the high school to NCAA Division I levels. In addition to his role as a professor and research mentor, Dr. Goodin directs the Athlete Monitoring Initiative at PLNU, which provides testing and monitoring services to over 200 athletes yearly as well as research opportunities for kinesiology students.

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.

[kayleebyon]

I always got confused as to what muscle did what in the arm/wrist, but Dr. Goodin's videos and descriptions helped so much! Especially the flexor muscle doing exactly the name

[IsabellaGunasayan]

i like how dr. goodin talks through the names of the muscles because it helps me picture where they are

[KarissaYeePL]

This video really helped me understand how the muscle actions and joint movements go together in the hand and wrist. This is very useful for refreshing my functional anatomy!

[BrookelynnAnderson]

During anatomy and physiology, the hand and wrist muscles confused me a lot due to how many there are and the long names for each muscle, this video helped me remember them more as Dr. Goodin gives details on how to remember each one.

[EmmaAlbrecht-ft]

I appreciate the way Dr. Goodin breaks down and thoroughly explains everything!

[ElizabethSatterlee]

It was really helpful that Dr. Goodin broke down the names of each so it is easier to remember their actions and make patterns.

[Knepperpepper]

I like how the name can sometimes correlate with its action and the location! Great video!

[rbello_]

I'm always so amazed at how intricate our bodies are and the detailed parts of the wrist flexors and extensors are great example of that. Crazy how one muscle can be for just one single digit.

[MicahMurphy-tyoe]

I loved how each of the actions were very well described and the structure of these videos are super well organized.

[JuliaPinnell]

I found this video to be a really great overview of the muscle actions. I really appreciated the in depth explanation to the flexors because those are the ones I always mix up!

[matthewwadley]

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.

[maceygroves]

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.

[madelinejewelnebril]

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.

[ellienichols]

i like how straightforward and easy to follow this video is!

[AlanaGilliland]

I really liked how much more in-depth this video went to include all the different muscles within the wrist and hand. In anatomy, we only learned a select few of the major ones, I always am so surprised to see how many muscles are in this area.

[laurenwahl]

The way you broke up the extensor carpi ulnaris muscle and showed the ways to remember what it does were really helpful!

[CharlizeSedgwick-bd]

This video was packed with material. I liked how the video was chunked into different sections based on what you were discussing. I appreciate you connecting different muscle actions to one another, helping us to notice a pattern.

[HadenAusland]

I found it helpful that Dr.Goodin always physically describes the muscle on himself as well as a detailed explanation/ way to memorize.

[braedenmoore]

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.
