How do you make the concepts so easy to grasp in just a few minutes!? Thank you so much!!

For a med student you have made biology easy, I don't understand why you haven't gotten much recognition, you deserve more

How do you guys always manage to post exactly what I need when I need it? Words can't express how grateful I am for all your hard work, you guys unlocked a new way of learning for me that has really brought the fun back into study. I now strive to draw cartoons to help me memorize and it really helps!!! Thank you so much!!!

Me watching this video to understand a concept my university professor would not be able to explain properly even if it meant saving his own life...

Amoeba Sisters are my heroes. I'm 50+, taking anatomy as I start a new career, and I would be lost without these incredible videos. Thank you!!!

You two are absolutely awesome. This has fueled my interest in biology for a long time!

Thank you so MUCH! I always watch a video before I read my chapter, because when I read the physiology-intense language and descriptions, I can see your animations in my head performing that action, and your narration takes over as soundtrack to my reading. It really solidifies the learning for me. I and my future patients thank you!

haven't watched this channel in a while but i must say thank you for helping me pass biology during my freshman year

I hope you guys can expand videos on the general genetics college content. Thank you for all the hard work!!

Biology teacher here - something my students and I have been researching recently is how healthy muscles experience âmicro tearsâ that eventually are healed and eventually result in muscle growth. In patients with Duchenneâs muscular dystrophy, we have learned that the sarcolemma rips without the dystrophin protein to keep myofibrils attached together. This causes a cascade of events that leads to cell death. What we havenât found a good explanatory mechanism for yet is how the oft-discussed âmicrotearsâ occur in healthy muscles. What is actually ripping? What does the healing? Any links, journal articles, or explanations are welcome!
Amoeba Sisters: thank you for your wonderful content !

Please don't ever stop making videos! I don't think I can ever show how much gratitude I have for making me understand things my teachers can't (sorry teachers). Thank you for making this world a better place, and thank you for your beautiful work Amoeba Sisters. More power to you guys! <3

I want to say thank you so much. You probably wont get a chance to read this but I had a surprise cumulative exam of all the info I learned in General Bio 1,2,3 and Chemistry in college. Long story short, I had taken a 6 year break from sophomore year to junior year and your videos saved me so much stress and anxiety. These videos are the perfect refresher for what I thought I had long sense forgotten. You two are literally saviors, without you I wouldn't have felt this confident to do this test.

What would I do without the Amoeba sisters , You make understanding and grasping the concept fun. Thank you â¤

Hi! I just wanted to say thank you, I finished high school not long ago and decided I wanted to look through some things for college. Iâve been watching some of your videos and I actually understand way more than I thought I would thanks to the way you explain it in a light and humorous way!
Thank you so much! Keep up the good work! :)

You guys always make complicated stuff easy and fun, thanks for keeping me sane in these trying times in med school

Unreal video. I was having trouble wrapping my head around the sliding filament theory. The illustrations are hilarious and the explain and description is easy to understand. Thank you so much for your help. All the best and have a wonderful dayQ

thank you! I definitely needed this for my college anatomy class i'm taking right now. I always find your videos at the right time!
