I can't possibly thank you enough for uploading this. My text book is pretty shitty and couldn't understand a thing by reading it and now that I've come across this video I do understand the bone lever system. THANK YOU! :)
I know it's been a long time since this text but anyway Your elbow act as the fulcrum and insertion point of brachialis muscle is away from fulcrum which act as Effort and the weight can be anything in hand Hence you first have the fulcrum then the effort and then the weight
The first class lever seems incorrect. The load and effort should both be applying force downward. This example shows the the effort applying force upwards as it would be in a second and third class lever.
Muscles can only pull towards their origin. The postural neck muscles (e.g. trapezius) would pull the posterior aspect of the skull downward. On the other hand, the anterior neck muscles (e.g. sternocleidomastoid) would pull the anterior aspect of the skill downwards. Hope that helps :)
@@munsta08 Reverse muscle action is pulling from origin to insertion therefor allowing muscle pull in both directions. I was referring to the diagram of the first class lever and not the actual example of it in the body.
Why exactly is this necessary for our knowledge? Even in a profession? Who the fuck cares whats a fulcrum in the body just as long as we know what body part we're referring to it makes no sense to add the fact that the elbow is a fulcrum like wtf
Uh - If you are a weight lifter you have probably wondered why it is so hard to get the same gains in your calves as in your chest, biceps, etc. It is because they are a second-class lever. This is part of the evolutionary history of the human body and makes for efficiency in bipedal walking. Therefore, to get big gains in your calves you have to "blast" them to overcome the inherent efficiency.

Sumaita Binte Shorif same here
Fantastic video! Informative and straight to the point
I'm sure i will go in to school with all the knowledge i need thanks to this video! thumbs up!
Heel joint is not the fulcrum, the metatarsophalangeal joint is the fulcrum

Thank you! It's amazing how many people get this wrong
ok. Photosynthesis
thx man, that really helped
This is totally helping me understand the different levers of the body. Thanks so much! :)
fac iu ez gaming ez pula gamer ez gg no re
Very good video and has enough information which I needed so I want to thank you so much
omg coz of that I just got a completely point of view how my bones and muscles move.
new*
this is very helpfull for ma during exams . thanks a lot for your kind effort
Good explanation 👍👍👍👍
Thanks
now i learn the diffrent type of lever
Thanks for the video I have learn this from you. Special thanks
Thank you so much. Very helpful video.
This was easy but you could have explained a bit more and slowly
I don't think it's the heel that acts as the fulcrum, but the toes, since the heel is moving up and down, right?
Lets go so great excellent revision g
Simple and to the point
So helpfull ... thank uuu so much😍😍
Fantastic vedio
Thank you DK Baseball Clinics for this link. This is excellent.
thank you. great video
Thank you so much
شكرًا
didnt they get the first lever wrong? the effort going the wrong direction??
Thanks for the given knolage
What single joint in the body can be used as a first- class lever and a second- class lever
Please help me
Simple but wow 😍
best video

amazing way of telling
Thanks a lot
Hello can someone tell me how I can create an animation of the human body like this?
Nice and simple
Which site we want to search for Biomechanics notes for 1st year BPT?
Same question
Isn't Elbow joint is a class 1 lever?
Correct me if I'm wrong
Because fulcrum comes in the center and effort and loads are in the two opposite ends
I know it's been a long time since this text but anyway
Your elbow act as the fulcrum and insertion point of brachialis muscle is away from fulcrum which act as Effort and the weight can be anything in hand
Hence you first have the fulcrum then the effort and then the weight
This is the way Joint Structure and Function says it too
@@Abdul_Basit120 I needed the explanation so thanks
@@safwanshahriar4108 no problem
Can someone explain to me how the anconeus is a first class lever? I don't full understand it.
Thank you, helped
