3D anatomy tutorial on the muscles of the larynx using the BioDigital Human (www.biodigitalhuman.com). This tutorial covers the following muscles:
- cricothyroid (straight, oblique)
- cricoarytenoid (posterior, lateral)
- interarytenoid (transverse, oblique)
- thyroarytenoid
- aryepiglottic
- thyroepiglottic
- vocalis

0:00 - Cricothyroid - pulls cricord forward downward), pulling/tensing vocal cords - Superior Laryngeal Nerve of Vagus nerve*.
3:05 - Posterior Cricoarytenoid - ABD-ucts vocal cords, opening - Recurrent Laryngeal Nerve of Vagus nerve
6:50 - Lateral Cricoarythenoid - ADD-ucts vocal cord - Recurrent Laryngeal Nerve of Vagus nerve
All intrinsic muscles innervated by recurrent laryngeal n. except cricothyroid (superior laryngeal nerve)
Thank you :')
Thanxx
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
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!
I feel you bro.. What shit education we had man...! :/ Have never understood this so clearly...
Divya Markande
which college can I ask ?
Sankhya Chatterjee SDM Medical College Dharwad.
Seriously!! 😔
Me doing neet pg coaching and seeing this comment from 8 yrs back saying the same things I want to say 😅
i've watches all your tutorials expalining the larnyx... and i'll definitly look over your other Videos too.... Thank you so much !!!
watching this to cram for my "anatomy for speech" exam tomorrow, you are a life saver!
These videos are GREAT, helpful study aids for my Voice Disorders class!! Thank you!!
These have been extremely helpful. Thank you for posting.
i've watched so many of your videos... really awesome stuff... please keep doin this more!!!
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.
no doubt you are a great anatomist! thank you so much for helping all medicoss....
In love with ur lectures
Extremely helpful! Thank you so much.
im from kerala....it helped me alott for my pg prepartion thanks alott
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 :)
*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*
You don't know how much you helped me
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!
Great video, thank you!
Hats off to ur effort
Thank you so much. This was so helpful
awesome channel for medical student
absolutely awesome. thank you thank you thank you!!!
Man
You are the best
thank goodness i saw this video. my exams are 6 months away and your videos have helped me tremendously!
awesome walkthrough of the structures! Thank you! :)
Thanks a lot!
Thanks for your help
go ahead .,, one of the best teacher I've ever seen
life saver!!!! thank you!
Thanks for your videos :-). I've used them a lot to supplement my graduate courses.
Thank You Verymuch
AWESOME!
thank you very much
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.
U r simply awesome
awesome ever. thank you from malaysia
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 😀
I am watching in 2018! Thank you so much!
thank you so much
Great video! !
Brilliant again :-)
This is a good video. Thanks!
Your videos should be taken as an example of how teaching should be , very informative and beneficial , thank you loads!
Amazing
helpfull videos thnxxx
awesome!
greetings from Palestine
simply amazing
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..
Thanks heaps for this!
*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
I think you might have got the vertical and oblique parts of the cricothyroid muscle swapped?
presstz4...right
Thanks a lot!! =D
Thanks a lot man
contrary to what most places on the internet says, the lateral cricoarytenoid actually opens the rima glottidis along with the posterior cricoarytenoid.
does anyone knows whom which anatomy atlas did he find this pics about the muscles?
Gray's anatomy... you can get those pictures in the google images
thanks british guy
Wow wow wow
You blundered in adduction and abduction part .. if there's anyway to edit it then it'll b good..
is this about a cat's? :(
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.

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