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)

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

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!

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!

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.
