The art of nostril flaring, also known as nasal dilatation or nasolabial expansion, has been practiced for centuries in various cultures and spiritual traditions. This technique involves expanding the nasal passages to enhance breathing, meditation, and overall respiratory well-being.
When it comes to flaring your nostrils, several key muscles play a crucial role in this process. The primary muscles responsible for nostril flaring are the Nasalis muscle and the Alaris muscle, both of which belong to the nasal cavity’s musculature.
The Nasalis muscle is located between the nostrils and is composed of two layers of smooth muscle tissue. When the Nasalis muscle contracts, it pulls the septum (the thin wall of cartilage and bone that separates the left and right nasal passages) laterally, widening the nasal cavity and expanding the nostrils. This contraction occurs involuntarily when the individual takes a deep breath or exhales forcefully.
The Alaris muscle is located at the lateral aspect of the nose and helps to dilate the nostrils by pulling the nostril walls outward and upward. The Alaris muscle works in conjunction with the Nasalis muscle to ensure proper nasal expansion and breathing.
In addition to these muscles, several other accessory muscles also contribute to nostril flaring, including:
The Levator Labii Superioris Muscle: This muscle helps to lift the upper lip and also plays a role in expanding the nasal cavity when the individual takes a deep breath.
The Zygomaticus Major Muscle: This muscle is responsible for smiling, but it also contributes to nostril flaring by pulling the nostrils outward and upward.
The Tensor Veli Palatini Muscle: This muscle helps to tense the soft palate and also plays a role in regulating nasal airflow when the individual practices nostril flaring exercises.
To effectively flare your nostrils, it’s essential to engage these muscles in a coordinated manner. One way to do this is by using specific breathing techniques, such as alternate nostril closure or box breathing.
When performing alternate nostril closure, the individual closes one nostril with the thumb and breathes through the other. This technique helps to strengthen the Nasalis muscle and improve nasal flexibility. Box breathing involves breathing in for a count of four, holding the breath for a count of seven, exhaling for a count of eight, and holding the breath again for a count of eleven. This pattern helps to calm the nervous system and regulate the breathing patterns.
Regular practice of nostril flaring exercises can lead to several benefits, including improved respiratory function, enhanced meditation skills, and increased overall well-being. By engaging the correct muscles in a coordinated manner and using specific breathing techniques, individuals can master the art of nostril flaring and unlock its numerous health benefits.
The act of flaring one’s _nostrils_ , also known as _flaring the nostrils_ , is a facial expression that involves the contraction of specific muscle groups in the face and head.
When the nose is flared, the following muscles are involved:
1. The Nose Lift muscles: These are small muscles located in the upper part of the nose, just below the nasolabial fold . They play a crucial role in lifting and flaring the nostrils.
2. The _Zygomaticus major muscle: This is a fan-shaped muscle that originates from the malar bone and inserts into the nose and lip. It helps to lift the corners of the mouth and, when activated, can cause the nostrils to flare.
3. The Nasalis muscle: Located in the bridge of the nose, this small muscle is responsible for spreading the nose outward and upward, which results in flaring the nostrils.
4. The Tarsal plate muscles: These are thin, fan-shaped muscles located in the lower part of the eyelid and surrounding the _tarsal cartilage_. When activated, they can contribute to the widening of the nasal opening and flaring of the nostrils.
5. The Orbicularis oculi muscle: Although primarily responsible for closing the eye, this muscle can also play a role in contracting the nostrils and causing them to flare when it’s involved in the coordinated movement with other muscles.
It’s worth noting that flaring the nostrils is not just about moving specific muscles; rather, it involves a complex interplay of facial expressions, breathing patterns, and even emotional states. For instance, when we’re excited or surprised, our body responds by tensing up, which can cause various muscle groups, including those involved in flaring the nostrils, to contract.
This intricate relationship between muscles and their corresponding functions highlights the incredible complexity of human facial expressions and the importance of understanding how different muscles work together to convey emotions and intentions.
External Nasal Muscles
The external nasal muscles are a group of muscles that control the movement of the nostrils, playing a crucial role in various facial expressions and functions.
- The primary muscles responsible for flaring the nostrils are the levator labii superioris alaeque nasi, which is part of the external nasal musculature. This muscle originates from the bony ridge above the root of the nose and inserts into the skin of the upper lip.
- Another important muscle in this group is the depressor septi nasi, which helps to narrow the nostrils by depressing the lower cartilage of the nose.
The levator labii superioris alaeque nasi muscle has two distinct functions: it elevates the upper lip and also helps to flare the nostrils when we’re excited, upset, or in situations where we need to express strong emotions. When this muscle contracts, it pulls the skin of the upper lip upwards and outwards, creating a widened appearance of the nostrils.
The movement of the levator labii superioris alaeque nasi muscle is involuntary, meaning that we don’t have conscious control over its contraction or relaxation. Instead, it’s regulated by the autonomic nervous system, which allows for automatic and reflexive responses to certain situations or emotions.
- Other muscles that contribute to the movement of the nostrils include the orbicularis oris, which encircles the mouth and helps to control the size of the nostrils; the zygomaticus major, which is responsible for smiling and raising the corners of the mouth; and the nasalis superior, which elevates the nasal bridge.
- The external nasal muscles also play a role in other facial expressions, such as frowning or squinting. When we’re feeling stressed or anxious, our nostrils may become flared and our eyebrows may furrow, all of which are influenced by the contraction of these muscles.
In addition to their role in facial expressions, the external nasal muscles also have functional implications for breathing and respiration. For example, when we flare our nostrils, it can help to increase airflow into the lungs during inhalation, allowing for more efficient oxygen uptake.
Internal Nasal Muscles
The internal nasal muscles, specifically the nasal conchae and surrounding smooth muscles, play a crucial role in regulating airflow and maintaining nasal patency.
These muscles are composed of cartilage and smooth muscle tissue, allowing for precise control over the movement of the nostrils.
- The nasal conchae are three pairs of curved bones located within the nasal cavity.
- They are covered in a thin layer of mucous membrane, which contains many tiny blood vessels and sensory receptors.
- The cartilaginous structure of the nasal conchae allows them to expand and contract, regulating airflow into the nose.
The surrounding smooth muscle fibers further aid in this process by providing additional control over the nostrils.
When these muscles contract, they draw the alar margin (the edge of the nostril) closer together, increasing airway resistance and promoting nasal congestion.
Conversely, when they relax, the alar margin spreads apart, decreasing airway resistance and facilitating easier breathing.
The movement of the nasal conchae and surrounding muscles is often referred to as “nasal constriction” or “rhinitis,” which helps regulate airflow and protect the delicate tissues within the nasal cavity.
For example, when we feel a cold coming on or are exposed to allergens, our body responds by increasing the size of the nasal conchae and surrounding muscles, preparing for an influx of mucus production.
In addition, these internal nasal muscles also play a role in other bodily functions such as regulating emotions, influencing social behavior, and controlling the involuntary response to threats or stressors.
Accessory Muscles and Nerve Control
The act of flaring one’s nostrils, often associated with intense emotions or strong reactions, involves the contraction of several accessory muscles.
These accessory muscles are smaller than the primary muscles responsible for breathing and are innervated by the _autonomic nervous system_, which regulates involuntary actions such as heart rate, digestion, and respiration.
The Zygomaticus major muscle, a key player in smiling, also makes a significant contribution to nostril flaring. This muscle is located within the _facial region_ and is responsible for elevating the outer corner of the mouth and, by extension, the nostrils.
When the Zygomaticus major contracts, it draws the lateral canthi (corners of the eye) closer together, creating a more pronounced smile. Simultaneously, it helps to flare the nostrils outward, as the nasal labial folds, which connect the nose and mouth, become more prominent.
The Facial nerve, a branch of the _cranial nerve VII_, is responsible for innervating the Zygomaticus major muscle among other facial muscles. This complex network of motor neurons allows for precise control over facial expressions and, consequently, the subtle movements involved in nostril flaring.
Other accessory muscles that contribute to nostril flaring include the _Orbicularis oris, which encircles the mouth, and the Nasalis muscle, which helps to expand the nasal passages. However, the Zygomaticus major plays a disproportionate role in this specific movement due to its unique anatomy and innervation.

The coordination of these accessory muscles is crucial for the subtle changes in nostril shape that occur during emotional expressions or other physiological states. By understanding the complex interplay between muscles and nerves, researchers can gain insight into the intricacies of human behavior and emotion regulation.
Furthermore, the study of facial expression and accessory muscle control has implications for fields such as psychology, neuroscience, and even medicine. For instance, alterations in facial nerve function or Zygomaticus major activity may be indicative of various neurological or psychiatric conditions.
