I love this video. 11 minutes you can understand the muscle of mastication VERY clearly. It totally worths. Though he repeated the same idea again and again, I never find him boring, instead, he is telling us not to confuse the origin and insertion. I would recommend this vid to everyone i know.

[@Gresilde]

Well done: clearest animation yet on the lateral pterygoids. They are the bane of my nocturnal bruxism and daily muscle dysfunction.

[@Anatomyzone]

No problem, I enjoy making them! I will definitely continue to produce them - I have just been extremely busy in the last few months and have had limited internet access, but look out for new tutorials in the near future! :)

[@zhiwaskalimba4096]

can't thank you enough ... those critising probably none of them could have done it quarter as good as you did..keep going

no problem! more to come soon, and looking to improve them as well! :)

Sir, m from India.. And m preparing for my post graduate course in medicine.. Ur videos are extremely useful for my exams.. Thanks a lot .. Million and billion of thanks..I got a good orientation of human anatomy ..

You must be an established specialist now? God bless you

[@topbidder1963]

Just for your benefit, there are many sources which indicate that the lateral pterygoid inserts both onto the condyle of the mandible, as well as the articular disk. Their belief is that the pterygoid is helping to anchor the disk to avoid any pathological dysfunction where it might pop anteriorly over the condyle (as a result, defeating its purpose within the joint). H owever, this video was extraordinarily helpful. Thank you so much!!! It is really appreciated!

[@bigbucksboer1]

I wish for just 1/2 doctors that I have visited had only 1/4 of the knowledge you have!!!!

[@ironlife615]

great video! not commonly talked about, but the mandible also has lateral movements during unilateral muscle activation

[@maestroh2986]

8:30 - removes the masseter: "cool" 8:34 - removes the mandible: "Waah!"

[@Anatomyzone]

Thank you for the comment, and sorry for my delay in replying. I have annotated this information into the video! :)

[@RicardoRodriguez-qb8kn]

It would help a bit more if you elaborated on how the lateral and medial pterygoids influence the TMJ and their action on bringing the jaw back to neutral at the end phase of mastication.

[@OJASVIVYAS]

sincere efforts are always appreciated...sooner or later...the amont of hardwork thats gone into this ....needs true appreciation..plz take care of contents also that r there in triangles..its a request..bye tc.

Thank you for the thorough explanation. Much appreciated!

[@wikayatzil530]

Mastication is the grinding and chewing of solid frod by the teeth.food is broken down into small pieces and mix with the saliva

[@jarvispereira6287]

you forgot to mention the lateral pterygoid is the only depressor of the mandible! quite significant as its the only muscle out of the 4 which does that! and its the zygomatic process of temporal bone not maxilla!!

[@drnimish333]

Nice video. Keep posting more of such videos.

[@pratyu2203]

omg!!!daz a awesome work ...thanku so so so much sir... am preparing for pg, n it helps me a lot... expecting more n more... .plz keep updating ..

[@ryanwrengifo3598]

great vids! couple of strange mistakes... you call the temporal process of the zygomatic bone the "zygomatic process of the maxilla". also you call the zygomatic process of the temporal bone the "zygomatic bone". (c. 4:25)

[@Notthetimeforit]

Ryan W Rengifo from what we have been told by my anatomy lecturer and by further research done from other university site I've found the zygomatic process of maxilla the origin along with the zygomatic arch.

[@genelakenetau]

Excellent video. You’ve summed up the basics in 12 minutes what I learned in a week long course. Great revision for me. Thank you so much for taking the time to post this.

[@praisycreates]

Superficial fibres of Lasseter does protraction and the deep fibres does retraction

[@Notthetimeforit]

Just for those reading the comments the zygomatic process of the maxilla along with the zygomatic arch for the origin of the masseter is right.

[@danyadanya1079]

very helpful but u confused between the orgin and insertion more than one time

The Masseter Muscle can also do Protrusion

[@Jiggy77XD]

No it cannot

[@palbrodin1558]

Jiggy77XD To prevent opening the Masseter and other jaw closers have to be active during Protrusion caused by the external Pterygoid muscle

[@Roy-dh9nt]

Jiggy77XD fucking idiot, when you say ‘no’, you should give a reason and explanation for the ‘No’

[@mutazaljuaid3650]

MISTAKE!!! 4:20 temporal process of zygomatic and zygomatic process of temporal. NOT zygomatic process of MAXILLA thanks 4 the video ;)

4 movements of mandible retraction ppsteriorly , protucion anteriorly Elevation superiorly Presses

[@radio-teb2018]

at 9th minute of the video you change the origin and insertion of Petrygoid muscles few times, I assume You mean Origination of the Petrygoid muscles are from Lateral Ptreygoid muscles Am I right? And the insertion of the lateral Pterygoid muscle is on Condylar mandible. Please help me with this confusing part of anatomy. Besides, why clinically these two muscles only originate from Lateral Pterygoid muscle I mean what is the clinical importance of it. Why medical Pterygoid muscle does is not supposed to originate from Medial plate of Pterygoid process? what you happen if so?

[@chrismyers7568]

cheers man making anat100 dealable

[@LyricsLandTrr]

Medial pterygoid elevation and Side to Side movement

[@niveditar2910]

The pterygoid muscles ORIGINATE on the lateral pterygoid, right? You kept saying insert.

[@devjanichaudhuri5356]

zygomatic arch = zyg proc of temporal and temp proc of zyg

[@lolazimmerman9779]

Great video!! Thank you!

[@blackout4338]

You forgot side to side movement. The muscles involved with side to side movement are, Medial pterygoid, Lateral pterygoid, Masseter and Temporalis.

[@Notthetimeforit]

Steven Hartshorn side to Side movement would just be the lateral and medial pterygoid. Masseter: jaw closure Temporalis: jaw closure, protrusion and elevation. Medial: protrude, elevate mandible and grinding. Lateral: protruding, sliding and grinding (back and forth, side to side

[@1TalldrinkH2O]

Great study! Thank you!

[@llubitzaslaviza]

Thank you so much for the video is very nice

[@dpbharkher4981]

Does medial pterygoid INSERT into the medial surface of lateral pterygoid plate? BD Chaurasia's Anatomy says it ORIGINATES from there. please confirm. Regards🙏

[@TahirKhan-kn6cd]

Please clarify how the mouth opens during mastication.

would you please give me a download link to that model.. im really confused of not being able to find an anatomical skull in my town

How long does mastication take?

why do you keep mixing origin and insertion again and again

Great series of videos but you always confuse insertion points with origins of muscles and I concur that coughing should be muted.

1:58 how to improve this muscle

[@hayabusa47]

Put implants like Brad Pitt :p

[@xxmonster45xx]

love your videos man theyre awesome but this isn't your greatest one at least with respect to the pterygoid haha-- its not really your fault though that model isn't exactly helping. if anyone is using this video for boards review id def recommend cross referencing a chart for the origins and insertions of the pterygoid muscles here. theres also some extra sort of minor actions that arent covered for some of the other muscles

[@LyricsLandTrr]

Masseter elevates the mandible

[@fatemabucheery7008]

Thank you!

[@cruzcham]

Thanks sir!

[@tarynswanton2447]

Amazing thank you.

[@syedatooba8848]

this video was definitely not of AZ's standard. Informative but could have been so much better if there wasn't so much confusion about insertion origin.

[@spirito96]

thanks a lot

[@papaaaaaaaaim]

wait... masseter does adduction AND protrusion! also what about the unliateral conractions? just reviewed the vid now for my upcoming finals and allthough i usually really like your videos, this is not one of your best =( sorry to say that... but keep on doing this vids! thanks for your effort!

[@Jiggy77XD]

Masseter does not protrude. Whoever has taught you that is incorrect. It can only elevate the mandible, nothing else. Protrusion of the mandible is produced initially by the lateral pterygoid for minor movements, and also medial pterygoid for larger protrusions.

[@Shalevbm]

Jiggy77XD you are mistaken, It would be great if you could back your information up with a verified source. please look at the following chart, taken from Moore - Clinically Oriented Anatomy 7th edition: www.dropbox.com/s/oi5uz7mffasq626/Capture.JPG?dl=0

[@animeshtalukder5422]

Just for your information, you've confused us & also yourself about the insertion of Lat. & Med. Pterygoid mus. All muscles here should insert in Mandible. But no offense! I really appreciate your endeavor. Please carry on!!

There isnt that much to explain about 4 muscles... and if he only said it once you'd have to play it over and over again anyway, unless you remember every insertion and origin the first time you hear it, if so I envy you :)
