MUSCLES OF FACIAL EXPRESSION AND MASTICATION

There are several groups of facial muscles: the oral group - in other words, muscles surrounding the mouth, the orbital group - or muscles associated with the eye socket, the nasal group - muscles surrounding the nose, the auricular group - or muscles surrounding the ears, and finally, muscles of the forehead and neck.
Let’s start with the oral group. Most of the facial muscles are positioned around the mouth, since this is the part of the face that moves the most. Firstly, there’s the orbicularis oris, which encircles the mouth. It is a sphincter - aka a circular muscle that maintains constriction of an orifice or passage of the body. This muscle helps you close your mouth, or pucker up your lips. It originates from the maxilla and from the other muscles of the cheek and inserts into the lips. The other muscles from the oral group can be divided into an upper and lower group. The upper group includes the zygomaticus major and minor, the risorius, the levator labii superioris, the levator labii superioris alaeque nasi, and the levator anguli oris.
The zygomaticus major and minor help lift the corners of your lips so you can smile. On the other hand, the risorius muscle is involved in the “fake smile”. Its contraction draws back the corners of the mouth into a smile shape. However, this smile does not collaborate with the orbicularis oculi muscles and so does not involve the skin around the eyes.
The levator anguli oris also plays a role in helping you smile by moving the corners of the mouth upwards. Meanwhile, the levator labii superioris alaeque nasi enables a snarling expression.
The lower group of oral muscles include the mentalis, the depressor anguli oris, and the depressor labii inferioris. The mentalis muscle is located at the furrow between your lower lip and chin, and is nicknamed the pouting muscle, since it helps contract the chin when expressing displeasure. The depressor anguli oris pulls down the corners of your mouth. Meanwhile, the depressor labii inferioris draws the lower lip down and sideways. So in general, the upper group generally is more involved in happy expressions, and the lower group is more involved in upset expressions.
The orbital group includes the orbicularis oculi, the corrugator supercilia, and the depressor supercilia. So the orbicularis oris isn’t the only muscle shaped like a donut. You also have a pair of orbicularis oris muscles encircling your eyelids. These muscles help you close your eyes, and again, these are sphincter muscles. The corrugator muscle pulls the eyebrows medially in most people. Finally, there is the depressor supercilia, which are thought to assist in moving and lowering the eyebrows.
The nasal group has three muscles in it. The nasalis is the largest, and can be split into the transverse nasalis and dilator naris. The transverse naris compresses the nares - or nostrils, while the dilator naris opens them. The procerus originates from the nasal bone, and inserts into the lower medial forehead. Its contraction pulls the eyebrows downward, wrinkling the nose. Finally, there’s the depressor septi nasi, which assists the alar part of the nasali in opening the nostrils. It runs from the maxilla to the nasal septum - the bone and cartilage separating the nasal cavity into two nostrils. There are three auricular muscles - the anterior, posterior, and superior auricular muscles.
Finally there is a muscle of facial expression in the forehead, and one in the neck. The frontalis muscle raises the eyebrows and wrinkles the forehead. In the neck, we have the platysma. It has three portions - the nodular, labial, and mandibular. Activation of the platysma causes slight wrinkling of the skin overtop.
Now for the muscles of mastication - these are associated with movements of the jaw. There are four of these - the temporalis, the masseter, and the medial and lateral pterygoids. The temporalis muscle closes the mouth and retracts the mandible. It originates from the temporal fossa and condenses into a tendon which connects to the mandible. The masseter is the strongest of the muscles of mastication. It can be split into two parts - the superficial masseter, and the deep masseter. Both these muscles elevate the mandible to close the mouth.
The medial pterygoid muscle closes the jaw by elevating the mandible. It has two heads - a deep one and a superficial one. The lateral pterygoid again has two heads - a superior and inferior one. Both heads are involved during the opening of the mouth - basically making sure the skull and jawbone are aligned properly at the temporomandibular joint. Finally, there’s the buccinator! This is an accessory muscle of mastication. Located between the mandible and maxilla, this muscle pulls the cheek in towards the teeth so food doesn’t accumulate there.
Your examples make it easy to memorize the muscles. This is such a big help!

Thank you so much😭❤ I was completely lost until I saw your video!
Cool, informative & clarfying! wish there were more animations of muscle movements in videos. Thanks!
Not only that was a very interesting explanation, but is also great for the study if you are into animation and 3D modeling! Thanks a lot!
Interesting to learn about the Pterygoids in relation to the TMJ. Thank you so making this content.
When you said 'supercilii' I legit heard it 'super silly' 🤣
This is glorious. The presenting pattern is very helpull to memorize.
This is such a great video! Thank you so much :)
The visual aid of showing what each muscle does for the facial expression really helps!
I have an exam next week, this really helped :)
Glad to have helped! :-D Good luck on your exam! This might also be helpful for you: ua-cam.com/video/qN5SDUNhQyU/v-deo.html
*Thank* You!!! I've gone through quite a few videos, and Yours is the First I can connect with! I've been a therapist for many years, and still learned something. The speed with which you show all this is best suited for refreshing rather than teaching; it feels a bit rushed to me. Still, excellent- I really like all the various ways you gave examples. : D
Normally I watch UA-cam videos at double speed, this is one of the only ones I’ve slowed down to .75. You can slow it down even further if it helps to take your time looking at the different muscles and making connections.
Nice video! Will repeat it over and over again! Thankyou
Fantastic video. So clear and informative, and you have most of the text below. Very kind of you.
I loved the video and mostly how clearly it was shown and stated . i would love you to talk about the skull, its nerves most especially with this same animation
so nicely done, thank you. it helped me with my spiritual meditation, to reflect on how with delicate care and wisdom we are created
seeing other people take action and have good results motivates me as well
Very very well put together. Thank you.
Very excellent. Thank you very much.
Well done ! Thank you so much
So thankful for these videos they're honestly amazing thank you! As I've dyslexia I struggle pronouncing words. My prime language is Irish so I struggle with English. I'm currently studying facial anatomy and this is an absolute godsend. Amazing amazing thank u

Thank you so much for ur explanation. it's very clear
I still find it genuinely amazing that we can control most of these muscles. 😮
Thanks, my smile looks a little crooked and when I looked closer... a muscle on my chin looked extremely tense and tight. I now know exactly what muscle it is that’s causing this and I can do further research. Thanks for this video!
Winner of a video, I have been researching "facelift yoga" for a while now, and I think this has helped. Have you heard people talk about - Jenrooklyn Facial Mummification - (Have a quick look on google cant remember the place now ) ? Ive heard some great things about it and my mate got great success with it.

Is there a way to enhance/train Zygomaticus major and minor in order to have more friendly expression in neutral? I see some people look more attractive, approachable and friendly based on their neutral expression while having corners of lips lifted by those muscles in their neutral expression, I assume there is some artificial way of altering its structure by for example undergoing beauty treatment injection or something like that but I would like to know if there’s another way to improve in that area, by some kind of exercise or idk.
thanks it hellep alot
Are there any exercises for people that had strokes?

Deep cervical facia
the depressor super silly
I am an artist who seeks to draw better. Bone anatomy is very helpful in understanding the face. But face muscles don't seem to show up well. How can I tell if a given facial form is due to fat or skin or muscle under the skin? In the face, these elements seem merged together. Analysis of photos might be helpful.
That's how yujiro did hmm... interesting
