Winking is a form of non-verbal communication that has been reported since biblical times. It involves the rapid closing and opening of one eye to convey a message, suggestion, or signal. While winking may be done in a joking spirit or to indicate friendliness, it can also suggest sexual interest. Interestingly, winking requires the coordinated contraction and relaxation of numerous muscles, with some sources stating that up to 49 muscles may be involved! The primary muscles responsible for winking include the orbicularis oculi, which closes the eye, and the levator palpebrae superioris, which opens it. These muscles, along with others like Müller's muscle, also play a crucial role in blinking and squinting.

What You'll Learn
The orbicularis oculi muscle
In some medical conditions, such as Marcus Gunn Jaw-Winking Syndrome and hemifacial spasm, winking can occur unintentionally. The inhibition of the orbicularis oculi muscle can lead to swelling under the eyes due to fluid buildup.

The levator palpebrae muscle
Winking is the rapid closing and opening of one eye to convey a message, suggestion, or signal. It is a form of non-verbal communication that involves the contraction and relaxation of multiple muscles in the face.
The orbicularis oculi is a facial muscle that closes the eyelids. It is connected to the lacrimnal pump mechanism, which aids in tear drainage and the lubrication of the eyes. The contraction of the orbicularis oculi muscle is essential for both involuntary blinking and voluntary winking.
In certain medical conditions, such as Marcus Gunn Jaw-Winking Syndrome and hemifacial spasm, individuals may experience unintentional winking. These conditions are believed to be associated with abnormal innervation or dysfunction of the levator muscle.

The Müller's muscle
Winking is the rapid closing and opening of one eye to convey a message, suggestion, or signal. It is the most universal non-verbal communication in the form of a facial expression that has been reported since biblical times. Winking may be done in a joking spirit or to suggest a feeling of friendliness, affection, or greeting. In certain cases, depending on the situation and associated body language, it might also signal a sexual interest.
The act of winking involves the coordinated contraction and relaxation of as many as 49 muscles. The main muscles involved in the upper eyelid, which control the opening and closing of the eye, are the orbicularis oculi and levator palpebrae superioris (LPS) muscle. The orbicularis oculi closes the eye, while the contraction of the levator palpebrae muscle opens it.
The Müllers muscle, or the superior tarsal muscle, is one of the muscles in the upper eyelid that is responsible for widening the eyes. It works in conjunction with the inferior palpebral muscle in the lower eyelid. These muscles are not only imperative in blinking but also important in many other functions such as squinting and winking. The inferior palpebral muscle is coordinated with the inferior rectus to pull down the lower lid when one looks down.
The Müllers muscle is, therefore, one of the many muscles involved in the complex process of winking. It works in coordination with other muscles in the eyelids to produce the rapid eye movements associated with winking.

The inferior palpebral muscle
Winking is the rapid closing and opening of one eye to convey a message, suggestion, or signal. It is a form of non-verbal communication that has been reported since biblical times. The orbicularis oculi and levator palpebrae superioris muscles in the upper eyelid control the opening and closing of the eye. The orbicularis oculi closes the eye, while the levator palpebrae causes the eye to open.
The levator palpebrae superioris muscle, often referred to as LPS, is a skeletal muscle that plays a crucial role in upper eyelid elevation. It originates in the posterior orbit and inserts into the orbicularis oculi muscle fibres of the upper eyelid. The LPS is responsible for eyelid opening, along with the smooth-muscle lid retractor, known as Müller's muscle. The LPS has a baseline level of tonic activation linked to alertness, and its function ceases during sleep.

Winking as non-verbal communication
Winking is a facial expression made by briefly closing one eye. It is a form of non-verbal communication that has been reported since biblical times. Winking is a rapid closing and opening of one eye to convey a message, suggestion, or signal. It is the most universal form of non-verbal communication through facial expressions.
Winking is an informal mode of non-verbal communication that usually signals shared hidden knowledge or intent. It is inherently ambiguous and highly dependent on additional context. Without this context, a wink could be misinterpreted or even nonsensical. For example, in some regions of the world, a wink may be considered rude or offensive. In China and some conservative parts of India, winking is not taken lightly. Instead, it is regarded as an expression of sexual advance.
Winking is one of the more subtle gestures, usually involving eye contact between the people involved. In most cases, it is only meant to be known by the sender and their intended receiver. However, in some cases, it can be more widely intended. A single wink is usually a friendly gesture, implying a degree of solidarity or intimacy. A typical use of the wink is to quietly send a message that third parties are not aware of. In certain cases, depending on the situation and associated body language, it might also signal a sexual interest.
There are different types of winks, such as the single wink and the double wink, each carrying a different connotation. A single wink may be done in a joking spirit or to suggest a feeling of friendliness, affection, or greeting. A double wink, on the other hand, may be used to imply that something said by the sender is "sneaky", "tricky", "misleading", or "untrue". In English-speaking countries, this has also led to the expression of saying "wink wink" while winking, or even without winking, to signal that one's words should not be taken literally but as a hint or euphemism.
