We've learned about the types of muscle, including skeletal muscle, and we know then when these muscles contract, we are able to move our bodies around. But how exactly does this happen on the molecular level? There is an astonishing amount of chemistry happening to make this work, so let's dive into those sarcomeres and take a look at the neuromuscular junction!

Crazy that I feel exactly the same way, come from sport science and sometimes the explanations of stuff are a bit hard to understand because too confusing, instead this make more sense

PROFESSOR DAVE sir you just saved my life. No amount of 'thank you's' could amount to how grateful I am for your videos!!

@mesozoicperiodvlogs8323 2 года назад

I just wanted to thank Professor Dave for helping me succeed in my scientific studies. I am a pre med student struggling to understand the complex inner workings of muscle contraction. I have been studying for at least eight hours now and i am absolutely exhausted, but this was a good final lecture to finish off the evening, and i will be returning back tomorrow to watch this video and others hes posted which are related to it., .thanks again Dave, we all sincerely appreciate you!

Totally cleared things up, my Anatomy and Physiology prof couldn't teach this well in the hour and 15 minutes I spend in that class.

@itsgonnabeanaurfromme Год назад

Prof dave is great and all but all he did was basically read out the steps. This can be found in physiology books. If you couldn't understand it before it means you weren't paying attention in class.

@draco4569 Год назад

@@itsgonnabeanaurfromme Reading from a textbook or listening to a lecture isn't a good learning method for some people, however. Sometimes, a video can cause these concepts to "click" within a person's mind in ways that reading from a textbook or listening to a lecture may fail to do. As such, these videos are much appreciated.
