I’m a 72 year old old orthopedic surgeon. I love watching your videos and I’m learning more than when I was a med student

[IHaveMagicPowers]

I'm a 6th year RN and going back into a cardiac specialty after a couple years away. This made more sense than when I was in Uni. Thanks team!

Amazing explanation. Studying for nursing school finals and this made an insane amount of sense!

[chelsead]

I watched this video a few times in undergrad while i was taking an anatomy course & here i am again now that Im in nursing school. no one describes this better than you lol

[fff]

This is absolutely the BEST explanation! Until now I honestly thought I was too dumb to grasp the concept of this, but now I realize no one has EVER been able to explained it in a way (to someone who has zero knowledge) that one can get their head around it and truly understand. Not just try remember a whole lot of info and hope it sticks, but completely understand! Which will only aid in further study, of the ECG for example. This then makes the next subject easier to understand and get your head around and so on and so on. Thank you so much!!!! you guys do an amazing job!!!!

This is my third time taking A&P and I'm sure I'll be here again in a year when I have to take it again but I've never understood mechanisms with such ease until your videos! Thank you so much from health profession students everywhere:)

[schola]

I've been reading about this and has been hard for me to understand. But after watching your video it has been so easy to get the concept. Please don't get tired of making our studies easier. Be much blessed

Brilliant! Your explanation, organization ( not to mention your wonderful accent ) help me tremendously! I wish I could give you my tuition fee! My professor should be ashame! Got an exam this Thursday! Feel better after watching this! We'll definitely watch your other videos. Keep it coming!

[dawnyyya]

tbh I really wish my instructor discussed this the way you do. Thank you, Dr. Mike, you saved me.

[marziarangel]

Thank you SO much for explaining in such an organized way, I am struggling with a professor who is brilliant, but disorganized so I had trouble following all the steps. This is perfect. THANK YOU AGAIN!!!

[sajadkasem]

Thank you sir
No body in my medical school did it like you
You're the best ❤❤

[AHMAaAD]

you don't understand how much your videos help me, thank you sir.

Great explanation! On another note, the calcium channel yields more calcium inside by triggering the through the sarcoplasmic reticulum. This maintains the plateau at phase 2 of the the action potential.

[jennifersalinas-alvarado]

You my friend have a gift. I could not make sense of this till I saw your video ( which came recommend by my teacher) I love how you give enough info without over loading us and you talk calm and smooth ( not fast and loud) amazing thanks again.
