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!

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!

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.

You were the best like all the timme but a little bet in a hurry. The speed of teaching was somewhat faster. But it was 100 times better than what other teachers explain.

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 Жыл бұрын

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!
