When it comes to puckering up, there's a lot more going on beneath the surface than meets the eye. The primary muscle involved in kissing is the orbicularis oris, which outlines the mouth and changes shape depending on how you move your mouth. This muscle is responsible for puckering the lips. However, it's just the beginning. A total of 34 facial muscles and 112 postural muscles are engaged during a kiss. Several muscles, including the genioglossus, styloglossus, palatoglossus, and hyoglossus, move the tongue during a kiss. The facial nerve plays a crucial role in carrying impulses between the brain and the muscles and skin in the face and tongue, transmitting sensations and triggering the release of hormones like oxytocin, dopamine, serotonin, and adrenaline.

The orbicularis oris muscle is the primary muscle involved in kissing
Kissing is a complex behaviour that requires significant muscular coordination. In total, 34 facial muscles and 112 postural muscles are used during a kiss. However, the primary muscle involved in kissing is the orbicularis oris muscle, which is also known informally as the kissing muscle. This muscle runs along the outside of the mouth and changes shape depending on how you move your mouth. When you kiss someone, the orbicularis oris muscle puckers your lips.
The orbicularis oris muscle is the star of the show when it comes to kissing, but it's not the only muscle involved. Several other muscles also play a supporting role in a kiss. For example, the zygomaticus major, zygomaticus minor, and levator labii superioris muscles all work together to pull your upper lip and the corners of your mouth upward. Additionally, if you decide to use your tongue during a kiss, several muscles come into play, including the genioglossus, styloglossus, palatoglossus, and hyoglossus muscles, which move your tongue.
The facial nerve is also an important component of kissing. It carries impulses between the brain and the muscles and skin in the face and tongue. During a kiss, the facial nerve transmits messages from the lips, tongue, and face to the brain, keeping it updated on all the latest developments. The brain then responds by releasing a cocktail of hormones and neurotransmitters, including oxytocin, dopamine, serotonin, and adrenaline. These chemicals play a role in attachment, emotion, pleasure, mood, and increasing heart rate, contributing to the intense physical and emotional experience of kissing.
While the orbicularis oris muscle is the primary muscle involved in the act of kissing, it's important to recognise that kissing is a multifaceted behaviour that involves a complex interplay between muscles, nerves, hormones, and emotions. The coordination of these various elements creates the unique experience and sensation of kissing. So, the next time you lean in for a kiss, remember that there's more to it than meets the eye!

Zygomaticus major, zygomaticus minor, and levator labii superioris pull the upper lip and mouth corners upward
The zygomaticus major, zygomaticus minor, and levator labii superioris are muscles that contribute to the movement of the upper lip and mouth corners. These muscles work together with other facial muscles to produce a range of expressions, including smiles, grins, and even expressions of contempt.
The zygomaticus major and minor muscles are responsible for lifting and everting the upper lip, contributing to various facial expressions, including smiling and grimacing. The zygomaticus minor, in particular, works in unison with other tractors of the upper lip to facilitate these expressions.
The levator labii superioris is a muscle located in the treatment area along with other facial muscles. It is a superficial elevator muscle of the nose and upper lip, utilised in oral-facial expression. This muscle works in conjunction with the upper lip's other muscles to elevate and evert the upper lip, exposing the maxillary teeth and deepening the nasolabial lines. The levator labii superioris is also involved in making certain facial expressions, such as smiling, grinning, and expressing contempt.
The identification of the levator labii superioris muscle can be challenging due to its proximity to other muscles, such as the levator labii superioris alaeque nasi (medially) and zygomaticus minor (laterally). These muscles also contribute to lifting the upper lip.
The zygomaticus major, zygomaticus minor, and levator labii superioris muscles play a crucial role in facial expressions, particularly in the upward movement of the upper lip and the corners of the mouth, contributing to the formation of smiles and other expressions.

Genioglossus, styloglossus, palatoglossus, and hyoglossus control tongue movement
Kissing involves several muscles, including those that move the tongue. The genioglossus, styloglossus, palatoglossus, and hyoglossus muscles all play a role in tongue movement. These are known as extrinsic muscles, which means that they originate outside the tongue but are functionally associated with it.
The genioglossus muscle is a large, thick, fan-shaped muscle that contributes significantly to the shape of the tongue. It originates from the mandibular symphysis and inserts onto the body of the hyoid bone and the entire length of the tongue. Bilateral contraction of this muscle depresses the central part of the tongue, creates a longitudinal furrow, and protrudes the tongue outside of the mouth. Unilateral contraction, on the other hand, will deviate the tongue contralaterally.
The styloglossus muscle is a thin, paired muscle located on either side of the oropharynx. It originates from the styloid process of the temporal bone and nearby stylomandibular ligament. To reach the tongue, it passes through the oropharyngeal triangle and inserts into the posterolateral aspects. By contracting, the styloglossus muscle retracts or retrudes the tongue and elevates its lateral aspects.
The palatoglossus is a bow-shaped muscle associated with both the tongue and the soft palate. It is the only muscle among the four mentioned that is supplied by the vagus nerve (CN X) rather than the hypoglossal nerve (CN XII).
The hyoglossus muscle is quadrangular in shape and originates from the body and greater horn of the hyoid bone. It passes through the oropharyngeal triangle and inserts into the inferior or ventral parts of the lateral tongue, between the genioglossus and styloglossus muscles. The hyoglossus muscle is involved in depressing and retracting the tongue.
These four muscles work together to produce tongue movements essential for various functions, including mastication (chewing), speech, and deglutition (swallowing). They also enable the tongue to protrude, retrude, depress, and elevate, movements that are integral to the act of kissing.

Muscles in the head, neck, and shoulders tilt the head during a kiss
Kissing is a complex behaviour that requires significant muscular coordination. A total of 34 facial muscles and 112 postural muscles are used during a kiss. The most important muscle involved in a kiss is the orbicularis oris muscle, which is used to pucker the lips and is often referred to as the kissing muscle. This muscle runs around the outside of the mouth, changing its shape as you move your mouth.
However, the orbicularis oris is just the beginning. Muscles in the head, neck, and shoulders tilt the head during a kiss. About two-thirds of people naturally tilt their heads to the right to avoid their noses colliding with their partner's. This preference may originate in the womb, as fetuses tend to favour turning their heads to the right.
Several other muscles also play a role in a more passionate kiss. For example, the zygomaticus major, zygomaticus minor, and levator labii superioris pull the upper lip and the corners of the mouth upward. Additionally, the genioglossus, styloglossus, palatoglossus, and hyoglossus muscles move the tongue.

The facial nerve carries impulses between the brain and the muscles and skin in the face and tongue
Kissing is a complex behaviour that involves significant muscular coordination. A total of 34 facial muscles and 112 postural muscles are used during a kiss. The orbicularis oris muscle, which runs around the outside of the mouth, is the primary muscle involved in kissing. This muscle changes the shape of the mouth during speech and puckers the lips during a kiss, making it the "kissing muscle".
However, several other muscles are involved in a more involved kiss. The Zygomaticus major, zygomaticus minor, and levator labii superioris pull the upper lip and the corners of the mouth upward. The genioglossus, styloglossus, palatoglossus, and hyoglossus move the tongue.
During a kiss, the facial nerve carries messages from the lips, tongue, and face to the brain, which then responds by ordering the body to produce various hormones and neurotransmitters. These include oxytocin, which fosters feelings of attachment and devotion, dopamine, which is involved in processing emotions and pleasure, serotonin, which affects mood, and adrenaline, which increases heart rate and triggers the fight-or-flight response.
Thus, the facial nerve plays a crucial role in transmitting impulses between the brain and the muscles and skin in the face and tongue, contributing to the complex emotional and physiological responses evoked by a kiss.
