Thank you so much for all ur videos ! I am studying for step 2 now and I always comeback to ur channel. A true hero 🙏🏻🙏🏻

[@dunndenndonndinn]

Thank you Dirty for another banger. One thing that helps me remember H-zone is "My(H)osin" and I-Band is "I be Actin Up". Good luck to everybody studying for exams, boards, and all the above! Yall are gonna crush it!

[@Rockerfeller26]

I like thinking of M-line as the 'myosin line' or the line that connects the myosin filaments. The 'H' band as the 'heavy' band cause that's where we have the 'heavy'/thick myosin filaments only. Then the A band as the 'all' band as it contains both the actin and myosin (including myosin on its own)

[@afshannizami5339]

great. liked yours better

[@ypk5]

This is hella smart. Ty

[@Rockerfeller26]

@@ypk5 don't make me blush☺️😂❤️ thank you for the kind comment

[@factscrub3755]

Dirty med, you are a beautiful human. I know it takes time and effort to do these and we appreciate everything you do!

[@dvperez14]

You are SO AMAZING! TRULY A BLESSING! YOU are fulfilling your goal of simplifying and making complex concepts so easy to comprehend. I appreciate you greatly.

[@kristelferrol]

This came right after getting an answer incorrect on Uworld. Thanks DM!

[@Dr.dugarte10]

Me too!! Hahahahah

[@srinivasachakradharearni6328]

Me too 😂

[@crystalruiz7609]

in human anatomy you have no idea how much this HELPED !!

[@RaverQuarterHorses]

This is so awesome! Thanks for sharing!

[@muhialdainmuhialdain7938]

[@Sam_1964]

This is an outstanding presentation

[@edward8691]

you are the best Dirty. no one could explains this better and easier than u do

[@kyy4018]

Very well explained. Made it so much easier for me to understand!

[@owensaenz1065]

This is amazing. Thanks, Dirty! If i can add, I also differentiate the H band and I band by looking at the width of the letters. H is thicker than I so it deals with myoTHICK. I is thinner, so I know I am dealing with acTHIN.

[@kathyf97]

this in incredible - thank you!!

[@miladkareem6454]

[@janicebenny3260]

Thank you!!!!!

[@hishamalhaysuni7865]

Thanks!

[@laetitiatraore8934]

thank you for this vid!

[@shubhagatasaha7161]

Perfect!

[@ChristinaMD-dt9vp]

Yes! The German word for midline is Mittellinie and apparently the Z line is "Zwischen= in between". I had no idea those had German origin but now It's going to be easier to remember them. Thank you for another amazing video!

[@deedhymaira2040]

You are the BEST 👌 👍

[@UdegbeDaniel]

Excellent

[@victorprokop9343]

have you looked at Stefan Rauser's stuff on sarcomere structure? its amazing what is being done with crazy resolution tomography

[@asadshah827]

You are a god amongst men

[@meh7070]

This is so not related to what i'm taking now, but i feel like i need to watch it since you uploaded it

[@Jameela201]

Really early on this 😊😊 Thank you Dirty ❤

[@FyslRhma]

Super ❤

[@YogiThenics]

Damm, you made it easy 😭✨

[@tshak7410]

Not sure if you did a video on it yet, but could you do one on bacterial genetics (transformation, transduction, etc), thanks!

[@asmasattar8369]

Hi you can also watch meet patel’s video on bacterial genetics. I found those helpful.

[@hannahbrown2290]

The rigor mortis physiology is actually quite high yield! I've seen it on many Step 1 NBME forms :)

[@deepalisharma8173]

Dirty med, thank you so much, you were absolutely right when you said, you made it easy compared to the overly priced crap i paid for 9:00

[@julietcapulet3082]

i got a question on rigor mortis on comsae! so it was useful haha

[@tysken0251]

how can a single z line move closer to two adjacent m lines simultaneously

[@alejandravalle6542]

I had a physiology question on Uworld about rigor mortis… answer was loss of ATP. ❤

[@andreainzaghi7373]

yes many tutorial videos but so much confusion! you can score where others have missed 😊

[@jtrobinson001]

You were right on, M-line --> mittle (Deutsche for middle) 😂

[@JJ-pn8lb]

😍😍😍

[@TheNeurophysiology]

But THIN filament is NOT only ACTIN. There proteins surrounding actin. Thin filaments include ACTIN, TROPONIN, TROPOMYOSIN. That is why striated muscles are THIN FILAMENT - REGULATED.

[@anantwadpatre3121]

😂😂😀👍

[@DrA902]

Am l the only one watching video to purely enjoyments 😂❤
