Whole muscle 3- Length/tension relationship

[@xoxlinds0]

YOU ARE SERIOUSLY THE BEST! I love your down to earth "dude's" and a little bit of "violence" that makes learning this enjoyable! ;) This is a very hard subject to grasp, but you definitely help make things make sense to us common folk! Thank you!

[@Chibbit1000]

I couldn't understand this before, and you've explained this perfectly in 7 minutes! I fully understand now, thank you, from Ireland !

[@alpr1864]

You rock. I'm a medical student and never have seen like you in my life.👌🏻

[@Onyi18]

I just want to say thank you. Thank you and thank you again. I wish you were my physio prof in med school. Nobody has ever explained it that way. Sometimes a little guidance is needed to understand intuitive concepts and you've done just that.

[@AlondraHernandex]

The last example about the runner was such a perfect way to picture it! Thank you. Love the energy!!

[@remma4403]

I did not understand this at all in my A&P class and now it makes complete sense. Thank you so much.

[@kelsseypierrelouis36]

OMG THANK YOU SO MUCH. WE FOR SURE NEED MORE TEACHERS LIKE YOU AND IM SO THANKFUL FOR THIS INFO.

[@markjones1444]

The intuitive part you are describing are proprioceptors. The muscle spindle detects the length of a muscle, while the Golgi tendon organ is responsible for monitoring the tension of a muscle.

[@cvetomirkirov9023]

Hi, great video! Can you please provide with a scientific reference about that?

[@namioncampusfsu7016]

love your energy and way of teaching!!

You can make your biceps longer by also extending at your shoulder.

[@dridihosni4140]

Full video please, I'm interested in the next unit which is flexibility

[@jocicalifornia]

Literally the best way this could have been explained, thank you! Plus you have a good mic, pls make more videos

[@sarahadam703]

I never understood that clear ... you are very gifted prof. I wish you teach us in our school

[@waggabidgee6781]

Hate to disagree with your explanation but...the primary reason for the difference in strength over the range of movement for this forearm flexion movement is the lever effect which changes the line of pull of the muscle. When lifting against gravity (vertically downward force) the optimal opposing force (vertically upward force) is when the elbow is at 90*. You will note in the sarcomere length-tension relationship that within the body the range of length in the sarcomere is only over the short middle range of the theoretical total length of the sarcomere. Therefore the lever design for the biceps favors maximal contraction when the elbow is flexed and is the real explanation of the change in strength over the full range of motion.

Wagga Bidgee Wendy's explanation is at the muscle cellular level, not practical real world use biomechanical level.

[@paulnicholas1278]

she's looking at each individual muscle cell not the whole muscle which has more of a gradient in positions

[@StevenLouisKane]

so so SO helpful thank you for ALL you've posted WENDY!!!

[@Mr_Ananas_]

I'm 7 years late lol But it's the best explanation I've ever seen, thank you so much 🙏

[@dusant.6370]

This is freaking awesome! Why does not professors explain like this?

[@husenkuliev157]

Enjoyable and very easy to understand!

[@keinyienchong1991]

Good video! Happy to find this video when I want to learn this concept.

[@silvertix2996]

Omg you’ve made doing medicine so much easier 😭❤️

[@thatboywolf9123]

great job explaining !!!

[@amarg7657]

thank you sooo much your explanation was so helpful

[@Playwithstudy664]

Nice explanation love❤😘 for your good teaching

[@jonathanjuarez3097]

really good video! it helped a lot

[@wildman166]

You rock Wendy !!!!!!

[@iskate40]

Wow this was super helpful thank you so much

[@shubhamthakur467]

You are the best teacher :) thank u so much for this awesome video; :)

[@dr.saadsiddiqui7343]

Best undoubtedly 👍👍

[@matanpeer2504]

So interesting! But I have one question: How come that the change in the actin-myosin overlap is only caused by the movement of the actin? It's clear for me that the actin is connected to the Z lines, and I thought that the myosin is connected to them as well... But now I see in your video that the myosin filament is not connected to the Z lines, so how does it stay static?

[@markjones1444]

Matan Peer The myosin is anchored in the middle by the "M" line.

[@mariatobin8385]

Awesome video. Makes me laugh. Thank you!

[@mahmoudabuelenein889]

Exceptional exceplaination

[@yousefalwkherii7112]

Good

[@kassygrapin1777]

you are the best thank you so much!!! :)

[@Fearless-1]

Whew...just a long winded way of saying peak muscle force is at mid length contraction!

[@jaysargent3502]

i love it :D

[@serpentus1488]

why is this a women teaching.

[@lbp7693]

I hope Lydia is divorced now.
