This is really cool Dr. Schaefer! I love the moves, the mnemonics and the music. You taught in 6 mins what most professors spend 2 hours doing. Thanks for sharing your talent.
Thank you, Dr. Schaefer. I first learned this from you in first-year anatomy at MSU. Now I'm a PGY-1 in FM studying for COMLEX Level 3 and am thankful this video is up on RU-vid. This dance has stuck with me over the years. Not only has it helped with many exams but also when caring for patients.
I've been struggling to remember/understand the myotomes for months for my upcoming ED primary exam. I was about ready to throw in the towel and accept i'll probably get any myotome question wrong. YOur dance helped me memorise them in less than 20 mins. You are the best
I am glad mam literally..... Since last year I was trying to learn this myotome and Dermatomes way hard.... But i am not able too...... Today uh made this so easy that i can't even imagine..... May God give you everything you want ☺.... You are the best 👍💯
Today my attending told Juniors to go and see the video. I came here straight away! 100% worth it what an awesome way to learn one of the most difficult topic.
This is super creative! I love coming up with creative things to remember class information so I’m glad I came across this while studying my dermatomes and myotomes for my final tomorrow! 😁
I believe you have some incorrect info, as you say L4 does knee extension. To my professional knowledge, L3 activates quads and does knee extension. L4, therefore, activates Tib Ant for dorsiflexion. L5 does big toe extension by Extensor Hallucis Longus.
Thank you for bringing up the fact that myotomes aren't black and white. Although myotomes are often taught as actions innervated by a single spinal level, multiple spinal nerves are often involved. The quads are innervated by the femoral nerve which is derived from L2, L3 and L4, so in reality, all three of those nerves contribute to knee extension. The dorsiflexors of the foot are innervated by the deep fibular nerve, which is derived from L4, L5, S1 and S2. Usually the spinal level that contributes most significantly is described, however this varies from resource to resource. Long story short, it depends on the resource that you are referencing as to the spinal level that is highlighted. I used Netter's.

Long story short, it depends on the resource that you are referencing as to the spinal level that is highlighted. I used Netter's. I have also noticed the spinal levels given tend to differ depending on whether the resource is intended for physical therapists versus physicians. I teach at a medical school, hence the reason I went with a more physician based resource. My guess is that L4 is highlighted as the knee extension myotome to keep it consistent with the patellar reflex being used to test L4.
Its true... myotomes are not black and white, since each action is performed from the contributions of multiple spinal levels. There are many resources out there that offer slightly different spinal levels or slightly different action. We teach knee extension as L4 to keep it consistent with patellar reflex testing, which is also L4. Bottom line is you can adapt the choreographer to meet your own needs, but hopefully the video at least gives you a baseline to make it your own. Thanks for addressing this important issue.
Thank you for your time doing this videos Iam student in physical therapy and i study from your videos to my final exams Thanks good my marks was excellent I wish you doing more videos and say your Instagram to follow you
