I genuinely appreciate how clear and engaging your videos are! A huge thanks for making complex topics so accessible and fun. Your help has been invaluable!

[@keniabeecroft288]

You are wonderful!!! You can make hard subjects super easy to learn. I truly appreciate all your videos. Thank you so so much for being such a talented teacher!
PS You're funny! You definitely can do sit-down comedy.

[@freedomisinyournextbreatht8870]

Preparing for an exam and I watched about 5 videos on this theory before finding yours! Absolutely love the clear precise way you explain things, draw the pictures as you go, and then recap at the end. So much gratitude to you and you have a new follower. Adding the clips of your family makes it all the better. Thanks again!

[@roosta141]

This is the easily clearest and best video I have come across on this subject.
Thank you so much!

[@kaonastensgaard3725]

Had to complete an assignment for my human physiology class based of this video lol great work!

Your videos and illustrations are absolutely incredible. You explain things where it’s easy to understand, and your illustrations are clear, colorful and beautiful.You make Anatomy enjoyable! I am a fan!!!!

[@amandamarshall7375]

I love your delivery of the material. You are clear, concise, and easy to listen to and understand! Thank you!!

[@OneAccordFitness]

This helped so much as we are to know 22-23 steps to write from excitation to cross bridge and finish with reset. Very clear, thank you.

[@user-wb2wh2rt1w]

Wow!! You made this chapter super easy!! Your art skill made it all!! Actually your explaning skill did most of them haha.
What an awesome lecture!! I am so lucky to watch your lecture. Thanks again!!

[@itsnotme_946]

I owe you my life

[@SiebertScience]

Go do a nice deed for someone else, and I'll consider the debt paid. ;)

[@mejojo924]

but there is atp needed for contraction how come you say there isnt

[@Nyaarlathotep]

Siebert Science

[@rkb8100]

I had Guillain-Barré and was left with weakness in my quads. How many neuro transmitters are there that stimulate a particular muscle? hundreds,thousands,millions? And perhaps mine didn’t all return?

[@SiebertScience]

Each muscle will have somewhere in the hundreds of thousands of muscles fibers, and each fiber has one motor neuron terminal connected to it.
The neurotransmitters are the tiny chemicals released from the axon terminal to the muscle fibers...not sure how many of those there are, but it's a lot!

[@rikkamae]

life saber

[@deltalima6703]

Not exactly. Close though.

[@PS-ch8sx]

Too fast

[@lucybrue1868]

Speak way too fast!

[@SiebertScience]

Sorry! I think you can adjust the playback speed of CZcams videos. Maybe slowing the video down could help?

[@deltalima6703]

Guy is wrong. You do not speak too fast. Volume is good too.
