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

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!

[michellethompson]

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

[zunazi]

How many speech therapy students are here?

[RoSii]

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.

*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*

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.
