What does Procerus mean?
Medical Definition of procerus : a facial muscle that arises from the nasal bone and a cartilage in the side of the nose and that inserts into the skin of the forehead between the eyebrows.
Where does the Procerus originate from?
Nasal bone
Procerus muscle
| Origin | Nasal bone, (superior part of) lateral nasal cartilage |
|---|---|
| Insertion | Skin of glabella, fibers of frontal belly of occipitofrontalis muscle |
| Action | Depresses medial end of eyebrow, wrinkles skin of glabella |
| Innervation | Temporal, lower zygomatic or buccal branches of facial nerve (CN VII) |
Where is the procerus muscle?
superior nasal region
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.
How do I relax my procerus muscle?
This stretch is great for relaxing the procerus….Stretching exercise :-
- Keep your face in a neutral position and place both of your index fingers on the bridge of your nose.
- With moderate pressure, glide your fingers firmly in an upward direction. Move through the stretch and hold for 5 seconds.
- Rest and repeat.
What is the origin of the nasalis?
Nasalis muscle
| Origin | Alar part: Frontal process of maxilla (superior to lateral incisor) Transverse part: Maxilla (superolateral to incisive fossa) |
|---|---|
| Action | Alar part: Depresses ala laterally, dilates nostrils Transverse part: Wrinkles skin of dorsum of nose |
| Innervation | Buccal branch of facial nerve (CN VII) |
What is the Modiolus of mouth?
The Latin term modiolus literally means “the nave of a wheel” and in dentistry refers to the point lateral to the angle of the mouth where several facial muscles converge. It has been described as coinciding with a muscular or tendinous node in the cheek and is considered to be important clinically.
What does the glabella do?
Typically, frown lines are the vertical lines between your eyes, while glabellar lines appear above your eyebrows and run horizontally. Frown lines don’t just come from making sad faces. When you smile, laugh, or look worried or surprised, the glabella muscles tug and pull the skin that covers them.
What nerve Innervates the procerus?
the facial nerve
In all specimens, the procerus muscle was supplied by the buccal branch of the facial nerve, which coursed infraorbitally. The number of the buccal branches varied: three in 47.8%, two in 47.8%, and one in 4.4% of the specimens.
What muscle makes angry eyebrows?
The corrugator supercilii muscle is a strong muscle that extends from bone near the top of the nose to the underside of the skin just above the mid portion of the eyebrow (glabella). Contraction of the corrugator causes vertical wrinkles between the eyebrows, often called “frown lines.”
Why do I furrow my brow when I sleep?
Sleep wrinkles are not attributed to muscle movement. They develop from repeated forces of stress or compression caused by the position of the head during sleep.
What causes the 11 wrinkles on forehead?
The 11’s are those vertical lines that appear between your brows and result from muscle contractions. When you concentrate, squint, or frown, the muscles between your brows contract, causing your skin to furrow and fold. After years of frequent contraction, those wrinkles can linger even after the muscles are at rest.
What is the longest muscle name?
levator labii superioris alaeque nasi muscle
The levator labii superioris alaeque nasi muscle is attached to the upper frontal process of the maxilla and inserts into the skin of the lateral part of the nostril and upper lip. It has the longest name of any muscle in an animal.
What is the skin below your eyebrow called?
The glabella, in humans, is the area of skin between the eyebrows and above the nose. The term also refers to the underlying bone that is slightly depressed, and joins the two brow ridges.
What does the procerus muscle do?
When contracting, the procerus muscle depresses the medial parts of the eyebrows and wrinkles the skin between them. This action enables frowning, making procerus an important contributor to the expansive array of human facial expressions.
What are wrinkles between eyebrows called?
Frown lines (also known as Glabellar lines) are vertical lines that develop between your eyebrows and nose when you frown due to contraction and movement of two facial muscles called the Procerus and Corrugators.
What muscle causes 11 lines?
These wrinkles are most commonly called 11 lines because they usually form in pairs on either side of the procerus muscles which run from the bridge of the nose to the center of the forehead. This is the muscle that acts to pull the skin of the center of the forehead down.
What are sad eyebrows called?
A frown (also known as a scowl) is a facial expression in which the eyebrows are brought together, and the forehead is wrinkled, usually indicating displeasure, sadness or worry, or less often confusion or concentration.
What is a furled brow?
When you concentrate really hard so that furrows appear in your forehead, you furrow your brow—an expression that means “worry, puzzle over.” When you lower a sail and wrap it tightly around the mast to secure it you furl it. If you can furl your brow you belong in a sideshow.
What is the origin of the procerus?
Procerus muscle originates from the nasal bone and superior part of the lateral nasal cartilage. Its muscle fibers diverge superiorly, mostly inserting into the dermis of skin over the glabella. A small portion of muscle fibers indistinguishably blend with the lower part of the frontal belly of occipitofrontalis muscle.
What happens when the procerus muscle contracts?
When contracting, the procerus muscle depresses the medial parts of the eyebrows and wrinkles the skin between them. This action enables frowning, making procerus an important contributor to the expansive array of human facial expressions.
What nerve innervates the procerus?
Innervation to procerus comes from the temporal, lower zygomatic or buccal branches of facial nerve (CN VII). Procerus muscle is supplied by the angular and lateral nasal branches of facial artery. Procerus muscle depresses the medial end of eyebrows and wrinkles the glabellar skin.
