The Mechanism of Muscle Contraction: Sarcomeres, Action Potential, and the Neuromuscular Junction

[@PrettyDocAJ]

I love how a confusing 2 hour class was summed in an easy 12-minute video! Thank you so much!

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

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!

2 hours of lecture, 1 hour of class asking questions, 1 hour of review next class... Students confused. Watch this 12 minute video. Concepts understood.

[@dramatriangle]

Yup

[@AlexNelson-jo5qv]

I've always wondered why this was the case. I think i figured it out. Lectures (and lecturers) contain to much information. They are there to provide all the information required to understand a topic, not necessarily in the best way possible. These youtube videos take you through the big picture concepts, and usually in a more dynamic format. Usually at this point, you'll have sat in a lecture, maybe reviewed the content a few times - and not really fully grasped the forest from the trees. These videos help you to cement the concepts, taking all the little details you've consumed along the way, and give them a proper skeleton to bind. That lightbulb moment or wow i get now, is coming from this process. It can happen in reverse, watch a youtube video prior to a lecture that covers the basics or larger concepts. Then in the lecture, you'll have all these little aha moments. Its quite fun (this is also known as priming)

[@aliyawilliams3584]

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

[@laurenk1139]

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.

[@7792pnaurfr]

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.

[@AKitchell]

@@7792pnaurfr 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.

[@unknownpitch]

I'm a zoology student ... I struggle a lot😭 by searching details in (Physiology/Mechanism of muscle constraction) This is very easy and super details. No wasting time like others videos do. Thank you very much sir. ❤️❤️❤️❤️ It really helps ❤️❤️❤️❤️❤️

In what scenario does a paramedic or nurse need to know this exact process? Serious question, please respond.

[@naomigwolfe8112]

By knowing this you can know how any why someone might be having contractions, seizing or lack of movement. Lack various chemicals in our body. Presence of electricity or other reasons will affect the muscles. The contractions also are important to know how they happen.
