Physiology of a Muscle Contraction.wmv

[@rh97979797]

Thanks a million for making your videos available. They are fantastic! Easy to understand!

[@TheUndiagnosed]

This is a really good video. I have suffered with weird muscle twitches all over my body for a few years now. This is the first time I find a clear and intelligent description of the topic. Thanks a lot.

[@oriondimension]

Watching this movie for an hour just saved me a day of useless book-study! Thank you so much for sharing your knowledge!!

[@ninetyandthree]

Thanks for providing these videos! They're always insightful and clear! Please continue producing your videos! They've been a tremendous help to me in my A&P course.

[@bullharrier]

@flowewritharoma You are very welcome, I'm glad this helped and thanks for the feedback.

[@ninetyandthree]

I think its pretty rad when "studying" means I get to kick back and watch your videos. Thanks for making them available!

[@RobotsGoRAWRR]

Great video. Sometimes my professor goes to fast so I don't get to retain much information. You were easy to understand and you made it very simple. Thank you! Keep up the good work!

[@dannylabelle6933]

thank you so much for this video.I'm doing A& P 2.we are currently doing the cardiovascular system ( the Heart) and I got confused with some of the events in the cardiac cycle.I needed to revise the basic concepts of membrane potential and skeletal muscle contraction.This was a thorough revision for me.Now i understand the topic better.

Your videos are really helpful! I would just like to ask about 25:52 where the Ca gates open at the boutons of the axon. Aren't these supposed to be Na gates and then the Na ions would be the ones to rush in? Since the depolarization process happens along the axon (wherein Na ions rush into the nerve cell), would it be the same in the axon terminals too? Or is there another explanation for this? Please do explain. Thanks.

Hey Aaron, First off thanks a lot for all your videos! With the calcium, is it actually being used up or does it just stay bound to the actin until the calcium is needed somewhere else? Also after each time the myosin needs to connect to the actin does the calcium "move over again" and block the myosin from connecting or does the connection spot stay open for extended periods of time? Lastly when someone is holding something without moving what is going on? Does it only "cock" so far???

[@bullharrier]

@donacuevas1 Thanks for the compliment, I'm glad this helped.

[@akcmiller]

Aaron Mullallly - Did you ever do a muscle metabolism video?

[@brittanyrendon-holm4865]

My professor speaks very poor English which makes these concepts even more difficult to grasp. Your videos are the only reason I have been successful in this class. Thank you so very much!

[@blondekas]

Thank you. I have a wonderful teacher but this helped fill in some gaps. Truly appreciate your post.

[@kungfu82able]

Thank you for helping me catch up in my Anatomy class. You're a lifesaver!

[@73kenman]

Are you working on some on twitches?

[@jpchristians]

Is the second weblink correct at the beging of the youtube video the physiol.med with the animation. I tried to search for it online but nothing came up. Thanks for your time

[@flowewritharoma]

thanks for creating this educational contents. simple is easy to understand.

[@tuberats99]

very good lecture man!! i'm from the other side of the planet and i can tell you it was awesome!

[@ninetyandthree]

Whats even more unbearable is that someone would criticize this guy after he has been generous enough to make these brilliantly insightful videos. I say "generous" because he could have just sat on his ass and talked shit on the internet (a likely indication of cowardice) instead of providing the public with his videos.

[@rythemailguy]

Great video, I have watched a few of your videos so far and they help my more than my anatomy teacher by a million times. So thank you for being so kind and uploading your lectures. I feel like I am taking a youtube anatomy class, but whatever gets me the A's. You should know I have a 97% in my anatomy class because of your videos:) Also, you could have left out the go Packers, as some of us are from Chicago. Haha j/k

[@jjittles]

Man your lectures are the shit! lol I have used your lectures to studdy at home on every topic since i found your lectures! These are verry helpfull I am glad you have made these!

[@bwabi93]

Thanks a lot Sir..i have really learnt from this and understoood..I sure now know where to come to with related physiology concepts

[@thugricanz]

Wow, your videos are so helpful. I wasn't paying attention in class on these days because I tend to always get lost since she's asian, so I can't understand her sometimes. I understand you very clearly. :)

[@whykayiskay]

Excellent! I finally get it.

[@QueenMinii]

This is great! Thanks!

What happens if you try to move a paralyzed person's body? Like, if someone was paralyzed in their legs, if someone tried to physically extend their leg, would it work?

[@JennVybzItGood]

I, actually, dealt with this when my exboyfriend was shot and paralyzed with a complete T2-T3 spinal cord injury. And when I took care of him for a year, and moved/exercised his legs- most of the time they would gravitate right back down. But sometimes, and I mean spontaneously, they would contract and jolt for a few seconds and then release back down. I really didn't understand that, so I'm very interested in seeing what Dr. Mullally has to say :)

[@anamed]

thank you!!! all your lectures are helpfull for my college classes.

[@hooksinger]

Doink lol this was grrrrreeeeaaat! I needed this!

[@erichaskell8882]

Packers baby!

[@abrhamlee]

thank you thank you very much.

[@CypherCZ]

I´ve made it for the first 20 minutes, but then I was so irritated by all those "Okay?" and "Allright?" that it was unbearable :/. Really a shame - the lecture itself was good.

[@TheWideSmile]

LOL. DOINK.
