There are 42 individual facial muscles in the face. To examine how each of these muscles impacts facial expressions, the researchers worked with people who are specially trained to be able to activate each and every one of those 42 muscles.
Are there 42 or 43 muscles in the face?
There are 43 muscles in the face, most of which are controlled by the cranial nerve (facial nerve). Seventeen of those muscles are used when you smile, and 43 of them are working when you frown.

- Temporoparietalis muscle.
- Procerus muscle.
- Nasalis muscle.

A muscle used in facial expression, primarily for smiling, the levator anguli oris elevates the angles of the mouth. The levator anguli oris originates roughly 1 cm inferior to the infraorbital foramen from the canine fossa of the maxilla and is located in the deepest layer of mimetic muscle.
What is Zygomaticus major?
Of all the muscles in the face, the zygomaticus major is perhaps the most noticeable. Sitting between the corners of our lips and the upper part of our cheeks, it controls the way in which we smile. The muscle sits atop the zygomatic bone, otherwise known as the cheekbone.
Where is the Triangularis?
Muscles of the head, face, and neck (labeled as triangularis near chin). The depressor anguli oris muscle (triangularis muscle) is a facial muscle. It originates from the mandible and inserts into the angle of the mouth. It is associated with frowning, as it depresses the corner of the mouth.

How many muscles it takes to frown?
Song of the University of Chicago Medical Center, however, frowning requires 11 muscles while smiling requires 12. This method of counting the number of muscles used in generating a facial expression does not take into account the energy consumed by each muscle or the individual variability in facial muscles.
How many muscles does it take to kiss?
Kissing can involve a variety of different facial muscles, with the orbicularis oris being the main skeletal muscle involved. Simple kisses use as few as 2 muscles and burn only 2 to 3 calories, whereas passionate kissing can involve as many as 23 to 34 facial muscles and 112 postural muscles.

Is there muscle in your cheek?
There are many muscles in the cheek region. The masseter muscle is the largest in the cheek region. The masseter contributes to the lateral fullness of the cheek, but its primary function is mastication. The lower part of the orbicularis oculi muscle contributes to the superior part of the cheek.

Participants found it easier to smile when exposed to images of smiles; the same effect was observed for frowns. Humans are wired to respond in kind because of mirror neurons, brain cells that fire both when we perform an action and observe the same action performed before us.

Zygomaticus major shown in red. The zygomaticus major muscle is a muscle of the human body. It extends from each zygomatic arch (cheekbone) to the corners of the mouth. It is a muscle of facial expression which draws the angle of the mouth superiorly and posteriorly to allow one to smile.
Where are the Frontalis?
Generally, the frontalis inserts at the eyebrow dermis and terminates laterally at the temporal ridge, but there is some variance and occasionally may terminate more medially as well. [10][11] While overall, it is a thin muscle with high vascularity, the bulk of it is located right above the brow.
What is Oris anatomy?
In human anatomy, the orbicularis oris muscle is a complex of muscles in the lips that encircles the mouth. It is a sphincter, or circular muscle, but it is actually composed of four independent quadrants that interlace and give only an appearance of circularity.
What muscle do you use to wink?
The orbicularis oculi muscle closes the eyelids and assists in pumping the tears from the eye into the nasolacrimal duct system. The orbital section of the orbicularis oculi is more involved in the voluntary closure of the eyelid, such as with winking and forced squeezing.
What is the platysma muscle?
The platysma is a broad muscle which arises from the fascia that covers the upper segments of the deltoid and pectoralis muscles. Its thin muscle fibers cross over the clavicle and proceed obliquely superiorly, laterally and medially over the neck.
What is the Risorius muscle?
The risorius muscle is a narrow bundle of muscle fibers that becomes narrower from its origin at the fascia of the lateral cheek over the parotid gland and superficial masseter and platysma muscles, to its insertion onto the skin of the angle of the mouth.
What is Buccinator muscle?
The buccinator muscle plays an active role along with orbicularis oris and superior constrictor muscle during swallowing, mastication, blowing, and sucking. It aids in mastication and blowing by compressing the cheek inwards.
Is the Platysma and sternocleidomastoid more anterior?
Platysma muscleArterybranches of the submental artery and suprascapular arteryNervecervical branch of the facial nerve
What's the action of depressor Anguli Oris?
Function. Depressor anguli oris pulls the angle of the mouth inferolaterally. Its action plays an important part in facial expression, as it helps expressing feelings of sadness or anger.
Where is the Procerus muscle?
The procerus muscle is a pyramidal-shaped muscle arising from the fascia of the superior nasal region, near the junction of the nasal bones, and the superolateral nasal cartilage. [1] The procerus muscle fibers run superiorly and merge with the frontalis muscle. Muscle fibers insert into the skin between the eyebrows.
