honestly this is just easy enough for me to still understand but it is absolutely mind-blowing that it basically happens instantly. I think go a car engine starting for example, as soon as you turn the key it sends the signal much like the Neurons do, and then the engine has to turnover, pump in fuel and air, ignite the mixture, allow it to explode, which moves the crankshaft and thus the drive shaft (well ignore the transmission) which turns the wheels and makes the care move. this whole process takes like a second or so and even still its unhealthy because you should bring your oil temp up and allow the transmission to engage properly before you just turn the engine on and go. But with our muscles its literally instant, which is so insane, its just as, if not more, complicated yet as soon as you think off something that action happens.
That chicken looks good.
what a great analogy he uses XD
Muscle Hank strikes again.
Who else is here from Mr.Wagner
Who is watching this during corona crisis?
OMG! you're so funny. Thank you.
I was not expecting to find Hank here lol
I'm actually taking a course on Exercise Physiology and these videos are really helpful since I learn better visually than just by reading and listening. Do you have a video on Neuro-muscular junction? Or, can you make one?
Superb….,why did you not include ligament in this video
I love Assassin's Creed, and I play it alot but thanks to you now I know how they are able to move around like that .Super humans with great muscle strength.
In his defense assasins creed it the best
hes so fine
