Super! I'm an MBBS graduate from India currently preparing for my entrance exams to postgraduate medical courses.. Your video simplifies 99% of the stuff! If only my Anatomy teachers had used these teaching aids in my 1st year! Thank you!

SUCH A GREAT STUDYING RESOURCE! Thank you so much for making this, not sure I would've passed Speech A&P without this guide!

How many speech therapy students are here?

Thanks so much! Can't tell you how many times I've watched this video

im from kerala....it helped me alott for my pg prepartion thanks alott

thank you so much for your tutorials. they help me a lot! keep up with the subtitles, they are great help with understanding what you say. not that there is anything wrong with your pronunciation but the terminology is really hard when you're a first year medstudent. could you please also put up tutorials about embryology? it is really hard to visualize how everything forms.

Thank you for this. I'm currently taking an anatomy class and my professor has been making this more confusing than clear. Thanks for that!

i've watches all your tutorials expalining the larnyx... and i'll definitly look over your other Videos too.... Thank you so much !!!

no doubt you are a great anatomist! thank you so much for helping all medicoss....

watching this to cram for my "anatomy for speech" exam tomorrow, you are a life saver!

You don't know how much you helped me

These have been extremely helpful. Thank you for posting.

These videos are GREAT, helpful study aids for my Voice Disorders class!! Thank you!!

thank goodness i saw this video. my exams are 6 months away and your videos have helped me tremendously!

Absolutely brilliant and super helpful. I am in CRNA school and this and your other tutorial are insanely helpful. I feel like I should send you some $...lol :)

I studied from your videos in my first and 2nd year MBBS and now after graduating im studying these for my postgrad exam Thanks Alot God bless you 😀

go ahead .,, one of the best teacher I've ever seen

In love with ur lectures

Thanks for your videos :-). I've used them a lot to supplement my graduate courses.

*Extrinsic muscles* These muscles move the larynx *up and down* during *swallowing* Many of these are attached to the hyoid bone which is strictly not a part of the larynx but attached to it superiorly via thyrohyoid membrane. Elevation 1.The digastric 2.The stylohyoid 3.The mylohyoid 4.The geniohyoid 5.The stylopharyngeus 6.The salpinopharyngeus 7.The palatopharyngeus Mnemonic The genious(geniohyoid) sapien(salpinopharyngeus) drank the milo(mylohyoid) with style squared(stylohyoid, stylopharyngeus). It suited his digestion(digastric) and palate(palatopharyngeus) Depression 1.Sternohyoid 2.Sternothyroid 3.Omohyoid Mnemonic *Stern* treatment made *omo depressed*

i've watched so many of your videos... really awesome stuff... please keep doin this more!!!

Hats off to ur effort

Man You are the best

awesome channel for medical student

Your videos should be taken as an example of how teaching should be , very informative and beneficial , thank you loads!

My right vocal chord has a wave motion when I talk. I do have a TBI suffered in 1977. I do have muscle damage on my right side firm the head to my pelvis, and multiple head injuries.

I am watching in 2018! Thank you so much!

Thank you so much. This was so helpful

awesome walkthrough of the structures! Thank you! :)

Thanks a lot!

Thank You Verymuch

Extremely helpful! Thank you so much.

Thanks for your help

awesome ever. thank you from malaysia

Great video, thank you!

I think you might have got the vertical and oblique parts of the cricothyroid muscle swapped?

This is a good video. Thanks!

U r simply awesome

absolutely awesome. thank you thank you thank you!!!

awesome! greetings from Palestine

Kind of confused how your larynx moves up when making a high pitched sound if the circothyroid pulls the larynx down and forward to tense the cords..

contrary to what most places on the internet says, the lateral cricoarytenoid actually opens the rima glottidis along with the posterior cricoarytenoid.

Great video! !

life saver!!!! thank you!

*Intrinsic muscles* Narrow the inlet Oblique aryteniod ligament Widen inlet Thyroepiglottic Tense the vocal cords Cricothyoid muscle Relax the vocal cord Thyroarytenoid(vocals) Adduct the vocal cords Lateral cricoaryteniod Abduct Posterior cricoaryteniod Approximate aryteniod cartilages Transverse aryteniod muscle

Thanks heaps for this!

AWESOME!

simply amazing

Amazing

helpfull videos thnxxx

Thanks a lot man

does anyone knows whom which anatomy atlas did he find this pics about the muscles?

thanks british guy

Brilliant again :-)

Thanks a lot!! =D

Wow wow wow

is this about a cat's? :(

You blundered in adduction and abduction part .. if there's anyway to edit it then it'll b good..

this isn't really correct, from a biomechanical or acoustic point of view. There are actually multiple ways to raise the pitch, so it's not correct to mention only stretching the folds to increase tension. It's also possible to resist stretch while increasing pressure, thus raising the frequency of oscillation. This bad information is confusing so many people who don't realize they should be figuring out another way to change the pitch! Many are confused by the basic idea that the CT and TA are doing everything people think they are doing. But it's this modeling that is incorrect. It doesn't make any sense at all, and that's even without nonlinear acoustics to explain missing forces contributing to fold closure. We are set up to expect simple muscle antagonism, and it's just not that.

haha your loss on some really good information.

Your british accent and haste makes it very difficult for me to understand :( Can you subtitle more?

:)

nani the fuck

thank you very much

thank you so much
