ECC Smooth Muscle

1:02... spa ci #pause fic allly

[duswdav]

where's caldesmon and calponin?

[SweepxThexLeg]

HAHHAHAAH this is while I love being half Filipino. We butcher English well.

Smooth muscle histology is also incorrectly shown here. There are no myofibers in smooth muscle.

[onelovelola]

Smooth muscle does contract via the myosin/actin cross bridge cycle. Smooth muscle, however, has a more complex cell signaling pathway for the release of Ca++ into the cytoplasm, as explained above. Calmodulin initiates smooth muscle contraction in the presence of Ca++ in contrast to troponin in skeletal muscle. Also, myosin phosphatase is needed to dephosphorylate the myosin heads before another ATP molecule can bind.

inappropriate information given....corrections 2 b done...

[jrev892003]

Correction: this is not smooth muscle. This is skeletal muscle contraction. :)

[001rizwan]

this is not smooth muscle it is skeletal muscle

[xchizophrenix1]

........ smooth muscle does not contract via a skeletal muscle bridge cycle as shown... that's the skeletal muscle.

thanks for the video! helped me a lot!

[NationalPro]

i have a midterm tomorrow and this is the explanation i get??? WELL NO THANKS!

[crickets37]

learning while having fun! tnx sa video na 'to...somehow, it helped me review for our exam dis week!:D

[floxich]

Salamat! Hanep yon ginawa ninyo! Ina-aralan ko eto =)

[IJoeSimmonsI]

Thank you for making this video and giving us a version in English!

[mrcolourblind]

Help:

i got lost briefly at 2:37

"CCMK phosphorylates the myosin regulatory light chain at the expense of ATP"

where does the CCMK act? Is it sitting on the myosin crossbridge? or does it catalyze binding of the ATP somehow?

Does "Myosin crossbridge" = "myosin regulatory light chain"?

[Gnamakala]

in what language is that?

[mod7t9z731]

good work and nice animation!

the illustration at 2:27 - 2:30 though seems to imply, that this mechanism is occuring at the skeletal muscle, which might lead to confusion.

[recyclingismylife]

really nice video, both in terms of production value and detail/information included, thank you all very much.

[krazyk18711]

calshium! haha

[mskovgard]

excellent detail. just what I needed.

[aymansays]

AWESOME!

[hypnonebula]

thank you...

[SuraSockan]

Awesome, finally a video with relevant details and use of correct terms!

Keep it up.

[Roxrockereyl]

I know they might try to sound "technological" speaking like that, but I think a lot more people would find it a lot more convenient if they speak normally. Still, this video is rather helpful, thanks.

[mikeysmith111]

what is saying, phospholipece? this bitch cant talk

[mrcolourblind]

@mikeysmith111

Haha! For sure!

I assume you meant "what is she saying?"

Maybe one day native english speakers will be smart enough to make quality education videos such as these too.

[eshely]

thanks a lot, well done

[Snyblind]

Much easier to understand now:) thanks

[leonciow]

This video is great explaining it. Thank you very much.
