The
That dimple is called the philtrum. It form because the upper lip originates in separate pieces coming from the left and right sides to fuse together early in the development of the face.
The first part of this question is easy – it's called your philtrum. Humans aren't the only ones to have some sort of crease in this place. Many mammals have them although they come in all sorts of shapes and sizes. For some animals, it's a way to help moisture travel between the mouth and the nose.
The philtrum is the most characteristic feature of the upper lip. Variations in its morphology can be seen amongst different individuals and races, but unusual presentations of the philtrum are relatively uncommon except in cases of orofacial defects, malformations, certain syndromes, trauma, and pathologies [1-3].
The philtrum is believed to serve as a supply of additional skin to be recruited for oral movements requiring stretching of the upper lip. The inferior margin of the philtrum forms the downward arch of the cupid's bow, while the underlying fleshy fullness is known as the tubercle or procheilon.
Overall, most respondents considered the young face (84%) and the aged face (68%) with philtral contours to be more attractive.
We all have them, though it's puzzled biologists for a long time as to why we do. I'm talking about that odd little groove found below your nose that runs to your top lip. Technically, it's known as your philtrum and it's as ubiquitous to the human face as the nose or eyes.
The philtrum—that groove we all have above our upper lips—may not be a commonly-referenced body part, but in Jewish mystical tradition, it's quite significant. And it's said to be the result of a tap from Lailah, the angel of conception, administered the moment a baby is born.
People with Noonan syndrome have distinctive facial features such as a deep groove in the area between the nose and mouth (philtrum ), widely spaced eyes that are usually pale blue or blue-green in color, and low-set ears that are rotated backward.
Femoral-facial syndrome (FFS), also known as femoral hypoplasia-unusual facies syndrome (FHUFS), is a rare and sporadic multiple congenital anomaly syndrome comprising bilateral femoral hypoplasia and characteristic facial features, such as long philtrum, thin upper lip, micrognathia with or without cleft palate, ...
Bunny lines are diagonal and vertical wrinkles that appear on the bridge of the nose and on either side of the nose with repeated contractions (squinting and laughing) of the nasalis muscle. Bunny lines cannot be found on everyone and are not universally disliked, but some people dislike them and decide to treat them.
Does Your Philtrum Get Longer With Age? Males genetically have a longer philtrum than females. For some men, their philtrum can drop by up to 5mm, whereas a female's philtrum may lengthen by around 3.5mm. With age, it continues to lengthen by an average of 0.5 mm every ten years.
A dent in the nose tip is generally a rare occurrence. It's caused by a relatively uncommon malformation where the nasal cartilages are very prominent and displaced from one another or if the overlying skin is thin and the cartilage edges are exposed.
There is another type of dimple that can be encountered rarely, such as fovea mentalis in the lower part of the mouth. It is observed at the bottom and single or double sided of the mouth corners.
During exercise our skin will thicken somewhat and when that happens the dimple remains attached to deeper tissues but the surrounding skin of the nose swells causing the dimple to appear larger and deeper. This is common on the nose because of the thickness of the skin on the nasal tip.
Williams syndrome is a rare (affecting 1 in 10,000 people) developmental disorder that can affect many parts of the body, including the heart and blood vessels. Children with Williams syndrome have mild to moderate intellectual disability, distinctive facial features, and an outgoing personality.
Jacobsen syndrome is a condition caused by a loss of genetic material from chromosome 11. Because this deletion occurs at the end (terminus) of the long (q) arm of chromosome 11, Jacobsen syndrome is also known as 11q terminal deletion disorder. The signs and symptoms of Jacobsen syndrome vary considerably.
The mouth is often small and the nasal tip is shortened while the philtrum is long and smooth. Some degree of intellectual disability and neurosensory hearing loss soon become evident. There is postnatal growth delay and most individuals are short in stature. The ears are low-set and rotated posteriorly.
Although the philtrum is vestigial in humans, in animals such as dogs, it is a deep channel designed to direct odorants from mouth to smell receptors of the nose. An interesting tradition about the human philtrum is expressed in the 1948 film, Key Largo.
The Latin and Ancient Greek root of “philtrum” is “love charm,” ascribing powers to what they considered one of the most arousing parts of the body. In humans, the shape of the philtrum is treated as a sexual commodity, even, subject to cosmetic surgery and shaping.
Aging of this area is characterized by perioral fine lines, marionette lines, and flattening of the cupid bow. The philtrum becomes longer and ill defined, indirectly contributing to a thinner upper lip. Furthermore, the dynamics of lip movement change with age.
Butterfly lip form is the rarest lip shape. This lip shape gives women strong expression and youthful appearance. Women mostly have this type of lip shape during puberty.
Cupid. Cupid is the rarest of all lip forms. Cupid has a powerful, youthful appearance, and is very prominent in pre-adolescent females. Due to the natural growth process in a female's lips, the fullness of the lips fill in the middle first, then the sides.
Full lips are the most common of shapes and are typically defined by lips that are equally plump on the top and bottom. This shape is easy to accentuate and looks great with bold lipstick looks.
