The philtrum or medial cleft, is a vertical indentation in the middle area of the upper lip, common In humans, the philtrum is formed where the nasomedial and maxillary processes meet during embryonic development. When these . Vermilion border · Frenulum of lower lip · Labial commissure of mouth; Philtrum. Cheek. Why do we have a groove between our upper lip and nose? Why not one on the bottom lip? What is the point located near the upper lip and nose called?. The upper lip is separated from the nose by the philtrum, the area that lies The upper and lower lips meet at the corners (angles) of the mouth, which are called.
Lips can also be used to suck in other contexts, such as sucking on a straw to drink liquids. Articulation[ edit ] The lips serve for creating different sounds—mainly labialbilabialand labiodental consonant sounds as well as vowel rounding —and thus are an important part of the speech apparatus.
The lips enable whistling and the performing of wind instruments such as the trumpet, clarinetflute, and saxophone. People who have hearing loss may unconsciously or consciously lip read to understand speech without needing to perceive the actual sounds.
Tactile organ[ edit ] The lip has many nerve endings and reacts as part of the tactile touch senses. Lips are very sensitive to touch, warmth, and cold.

It is therefore an important aid for exploring unknown objects for babies and toddlers. Lips of a young woman wearing red lipstick Lips of a young man Because of their high number of nerve endings, the lips are an erogenous zone. The lips therefore play a crucial role in kissing and other acts of intimacy.
A woman's lips are also a visible expression of her fertility. In studies performed on the science of human attraction, psychologists have concluded that a woman's facial and sexual attractiveness is closely linked to the makeup of her hormones during puberty and development.
Contrary to the effects of testosterone on a man's facial structure, the effects of a woman's oestrogen levels serve to maintain a relatively "childlike" and youthful facial structure during puberty and during final maturation. It has been shown that the more oestrogen a woman has, the larger her eyes and the fuller her lips, characteristics which are perceived as more feminine.
A woman's lipstick or collagen lip enhancement attempts to take advantage of this fact by creating the illusion that a woman has more oestrogen than she actually has, and thus that she is more fertile and attractive. Women are attracted to men with masculine lips, that are more middle size and not too big or too small; they are to be rugged and sensual.
In general, the researchers found that a small nose, big eyes and voluptuous lips are sexually attractive both in men and women. This article needs additional citations for verification. This technique was met with high patient satisfaction and no adverse effects. Persistence of injected nonanimal-sourced stabilized hyaluronic acid was similar to that seen in other studies. The lips are an essential component of facial symmetry and aesthetics.

Anthropometric studies have shown that wider and fuller lips in relation to facial width as well as greater vermilion height are a mark of female attractiveness. Full lips have become increasingly desirable as they are considered both youthful and beautiful.
Moreover, a trend has been identified toward fuller and more anteriorly positioned lips in models appearing in magazines over the past century.What does your Lips say about You - Thick upper lip & Thick lower lip - Face Reading
Such vermilion hypoplasia, when not present in youth, is often present with aging. Gonzalez-Ulloa 3 has described the changes of the lip with aging, including a less exposed vermilion, a relative loss of vermilion bulk, and lengthening of the lip.
It is possible to enlarge, refine, shorten, and reshape the lips with surgical techniques, 4 - 13 most of which can offer long-term results. The first few generations of injectable soft-tissue fillers such as bovine collagen Zyderm and Zyplast; Allergan Inc, Irvine, California offer patients a nonsurgical, yet short-term, means of improving their appearance.
Labial commissure of mouth
Although injectable collagen offers greater versatility to reshape and augment the lip than any one surgical technique, its short persistence in the mobile lip made it a less desirable choice of treatment. With the advent of longer-lasting, nonallergic, nonanimal-sourced stabilized hyaluronic acid NASHA gel fillers, 14 - 18 injection techniques have evolved.
What follows is my description of a new classification of 15 anatomical lip zones that I use to direct placement of injectable fillers and to improve my ability to customize lip contour and size to the patient's desire. I present my experience using an injectable, NASHA gel product Restylane; Medicis Aesthetic Inc, Scottsdale, Arizona to augment the lips in this fashion, including persistence data based on patient subjective review.
Deglutition Lips push food into the oral cavity proper during the voluntary phase of swallowing where it is ingested and prepared for digestion in the stomach and small intestine. Articulation The lips serve for creating different sounds — mainly labial, and labiodental consonant sounds.
Tactile organ The lip has many nerve endings and reacts as part of the tactile senses. Lips are very sensitive to touch, warmth and cold. Erogenous zone Because of their high number of nerve endings, the lips are an erogenous zone.
The lips therefore play a crucial role in osculation and other acts of intimacy. Facial expressions The lips form an integral part of facial expression e.
Anatomical landmarks of the lip. Lip anatomy The upper lip lies between the nose and the orifice of the oral cavity.
Laterally the lips are separated from the cheeks by the nasolabial grooves that extend from the nose and pass approximately 1 cm lateral to the angles of the mouth. These grooves or folds are easier to observe when smiling.
Philtrum - Wikipedia
The upper lip has an infranasal depression, the philtrum Greek for love-charmthat extends from the external nasal septum, separating the nostrils, to the vermillion border — the sharp demarcation between the coloured edge of the lip and surrounding skin.
The lower lip lies between the mouth and the labiomental groove, which separates the lower lip form the chin . The upper and lower lips are continuous at the angles of the mouth or oral commissures Table 1. In adults the outer lip skin is thicker and contains hair, sweat glands, and sebaceous glands. The edges of the lips are covered with reddish skin, called the vermillion, and are abundantly provided with sensitive nerve endings.
The vermillion is a transition layer between the outer, hair-bearing tissue and the inner mucous membrane. The skin of the vermillion is made up of three to five cellular layers and is very thin compared to the skin on the rest of the face, which is typically arranged in 16 cellular layers.
The mucous membrane of the lip is full of capillaries that are close to the translucent surface of the vermillion, giving it its characteristic reddish colour. In newborn infants the inner surface is much thicker, with sebaceous glands and minute projections called papillae. These structural adaptations seem to aid the process of sucking . The upper lip labium superioris is superior in name only since it is actually somewhat smaller than its partner, the lower lip labium inferioris.
In an ideal world, the lower lip vermillion show should be Phi times greater than the upper vermillion. However, that ratio can vary dramatically with ethnic background, and even from individual to individual within the same ethnic group. Therefore, it does not have the usual protective layer of sweat and body oils which keep the skin smooth, inhibit pathogens, and regulate warmth. For these reasons, the lips dry out faster and become chapped more easily.
The skin of the lips is categorised as stratified squamous epithelium, or flattened tissue cells. The outer lip skin is keratinised stratified squamous epithelium with numerous hair follicles. As the epithelium approaches the so-called red area of the lip, the epithelium becomes non-keratinised stratified squamous epithelium.
This type of epithelium is designed for protection and lubrication during chewing and swallowing.

Anatomy of normal orbicularis oris muscle: Orbicularis oris The orbicularis oris muscle, the lip muscle, is a broad elliptical muscle around the mouth Figure 2. When the orbicularis oris is tonically contracted, the mouth is closed, whereas active phasic contraction causes the mouth orifice to become narrower as when kissing or whistling.
Its lateral fibres join the modiolus, a chiasma of facial muscles held together by fibrous tissue, located lateral and slightly superior to each angle of the mouth.
