You're absolutely right! I need to write bigger...I'm going to try to do that in future videos. =)

[@khanacademymedicine]

Actually, my name is Rishi Desai and I work with Sal. No cold...that's just my voice.

[@sansan5507]

OMG THANK YOU SO SO SO MUCH YOU ARE A LIFE SAVER MEN!!!!THAT HELPED ME A LOT!!! so good job and keep the haed work ^^

[@JS-dq7jw]

amazing video, it helped a lot thank you! But, there's a small mistake. Nuclei is when you're referring to the plural form of NUCLEUS therefore you should say 1 nucleus and 2 or more nuclei. Apart from that- amazing video thank you!

[@alexaandlouellacruz442]

Thank you very much! You helped me a lot understanding all these things😊😊😊

[@nellaskitchen6509]

I watched your clip a couple of times to help me for an exam on types of muscle tissues, which I found very helpful. On the day on exam, I was able identify the skeletal muscle tissue, label and state function; furthermore I mentioned that it was the fastest moving muscle tissue. However my teacher said it was wrong (he said cardiac muscle tissues is the fastest). I tried to look in books and internet cant find the answer,WHICH IS THE FASTEST MUSCLE TISSUE????

[@borispetkov5079]

From my understanding of your statement, you want to know which muscle type out of skeletal and cardiac has the shortest contraction time. i.e the shortest time from the moment the muscle produces force in response to increased intra-cellular calcium to the re-absorption of Ca into the SR to dismantle the cross bridges and relaxation of the muscle. This is called a twitch, the brief mechanical contraction induced by a single action potential. If you agree so far, then we are looking for the muscle type that facilitates the fastest twitch response. That being the Type two fast twitch skeletal muscle at around 100ms. The cardiac around 300ms. All info is from my physiology lectures at med school :) I hope this has helped.

[@taibashah9607]

is cardiac muscle contraction slow or fast

[@angie70944]

cardiac muscles also have intercalated disk which is a big difference from the rest of the muscles.

[@nb8947]

Really clear and informative vid. But at the start you attached the rectus femoris to the femur at both ends, that wouldn't allow any movement!

[@auroralucrezia6514]

brilliant video thanks, but what did they do to his voice? voice sounds a bit robotic

[@OneBananaa]

its a different person teaching not by that main guy who founded it....i think

[@avadheshyadav7689]

very good video

[@vennesajanet9545]

[@alinn_tatu]

What type of muscle develops the most strength?

[@psihokiller4]

well actually what about of 3 types of muscles? Strength Explosion Endurance (I hope it's the right name) (how much food does muscle have)

[@SuperBrujita2009]

really good video, thank you! Do you have a video that explains the teased smooth muscle? the voice is not "robotic" it is good :o)

[@swinxfee]

1 nucleUS

[@chickenfarmer321]

Are the muscles in your lungs voluntary or involuntary? You can breathe without thinking about it, but you can control it...

[@henryott5070]

haha

[@523101997]

you can control the intake of air through your nose and mouth which are voluntary but once it reaches your lungs, they will work without you controlling it.

[@drabdirahmansaladibrahim4602]

+Brian Ung is the pressure diffrence also forcing the air out and in

[@galikazoid]

the respiratory diaphragm is the muscle that controls/deals with breathing, it can be voluntary, but it is also activated involuntarily most of the time

[@523101997]

galikazoid yeah, also the lungs arent really a muscle, oxygen and carbon dioxide travel by diffusion, which of couse is involuntary

[@quratulainadnan1162]

love these videos. just one thing though. heart is in the middle of the body, not on the left...its just tilted towards the left

[@HalosWorld214]

Helped Me Do My School Work c;

[@wild.Petals79]

You sound different, is it you khan? Did u have a cold during making that video?

[@cathimccracken6163]

Good content, but hearing you refer to "one nuclei" just sets my teeth on edge. Nucleus is singular, nuclei is plural.

[@David-tb9rf]

Aagh. I didn't want to be a jerk, but same.

[@LonghornLongboarder]

....Or when you give your mom a hug. We don't hug.

[@thecrasianasian4707]

guy sounds like tetraninja

[@Asaji14]

Finally someone to replace Sal, his voice is so annoying

[@KarenSelickKAS]

Nuclei is plural. Nucleus is singular.

[@backinhome4860]

Who is in 2020 lmao

[@asamoahgabriel1268]

🥰🥰

[@krislandoy4670]

hey what is the meaning of nuclei pls msg me i hope thx for your consern

[@MadhuSharma-ob7ne]

it singular of nucleus.

[@studentnursesaima5836]

Am I the only one who thinks the smooth muscle he drew looks like a kakugan... Tokyo ghoul fans?

And nucleiS is not a word.
