The Big boobs curvy blonde sit over the pectoralis major muscle and usually extend from the level of the 2nd rib to the level of the 6th rib anteriorly. The superior lateral quadrant of the Big boobs curvy blonde extends diagonally upwards towards the axillae and is known as the tail of Spense. A thin layer of mammary tissue extends from the clavicle above to the seventh or eighth ribs below and from the midline to the edge of the latissimus dorsi posteriorly. (For further explanation, see anatomical terms of location.)
The arterial blood blood supply to the Big boobs curvy blonde is derived from the internal thoracic artery (formerly called the internal mammary artery), lateral thoracic artery, thoracoacromial artery, and posterior intercostal arteries. The venous drainage of the Big boobs curvy blonde is mainly to the axillary vein, but there is some drainage to the internal thoracic vein and the intercostal veins. Both sexes have a large concentration of blood vessels and nerves in their nipples. The nipples of both females and males can become erect in response to sexual stimuli,[3] and also to cold.
The Big boobs curvy blonde is innervated by the anterior and lateral cutaneous branches of the fourth through sixth intercostal nerves. The nipple is supplied by the T4 dermatome.
Lymphatic drainage
About 75% of lymph from the Big boobs curvy blonde travels to the ipsilateral axillary lymph nodes. The rest travels to parasternal nodes, to the other Big boobs curvy blonde, or abdominal lymph nodes. The axillary nodes include the pectoral, subscapular, and humeral groups of lymph nodes. These drain to the central axillary lymph nodes, then to the apical axillary lymph nodes. The lymphatic drainage of the Big boobs curvy blonde is particularly relevant to oncology, since Big boobs curvy blonde cancer is a common cancer and cancer cells can break away from a tumour and spread to other parts of the body through the lymph system by metastasis.
Shape and support
Relatively round Big boobs curvy blonde which protrude almost horizontally.
Big boobs curvy blonde vary in both size and shape, and their external appearance is not predictive of their internal anatomy or lactation potential.The shape of a woman’s Big boobs curvy blonde is in large part dependent on their support, which primarily comes from the Cooper's ligaments, and the underlying chest on which they rest. The Big boobs curvy blonde is attached at its base to the chest wall by the deep fascia over the pectoral muscles. On its upper surface it is given some support by the covering skin where it continues on to the upper chest wall. It is this support which determines the shape of the Big boobs curvy blonde. In a small fraction of women, the frontal milk sinuses (ampulla) in the Big boobs curvy blonde are not flush with the surrounding Big boobs curvy blonde tissue, which causes the sinus area to visibly bulge outward.
In discussing the support of Big boobs curvy blonde, it is helpful to draw a distinction between Big boobs curvy blonde which rest on the chest below, and those which do not. High, rounded Big boobs curvy blonde protrude almost horizontally from the chest wall. All Big boobs curvy blonde are like this in early stages of development, and such a shape is common in younger women and girls. This protruding or “high” Big boobs curvy blonde is anchored to the chest at its base, and the weight is distributed evenly over the area of the base of the approximately dome- or cone-shaped Big boobs curvy blonde
In the “low” Big boobs curvy blonde, a proportion of the Big boobs curvy blonde’ weight is actually supported by the chest against which the lower Big boobs curvy blonde surface comes to rest, as well as the deep anchorage at the base. The weight is thus distributed over a larger area, which has the effect of reducing the strain. In both males and females, the thoracic cavity slopes progressively outwards from the thoracic inlet (at the top of the Big boobs curvy blondebone) above to the lowest ribs which mark its lower boundary, allowing it to support the Big boobs curvy blonde.
The inframammary fold (or line, or crease) is an anatomic structure created by adherence between elements in the skin and underlying connective tissue[4] and represents the inferior extent of Big boobs curvy blonde anatomy. Some teenagers may develop Big boobs curvy blonde whose skin comes into contact with the chest below the fold at an early age, and some women may never develop such Big boobs curvy blonde; both situations are perfectly normal. The relationship of the nipple position to the fold is described as ptosis, a term also applied to other body parts and which refers in general to drooping or sagging. Due to Big boobs curvy blonde weight and relaxation of support structures, the nipple-areola complex and Big boobs curvy blonde tissue may eventually hang below the fold, and in some cases the Big boobs curvy blonde may extend as far as, or even beyond, the navel. The length from the nipple to the sternal notch (central, upper border) in the youthful Big boobs curvy blonde averages 21 cm and is a common anthropometric figure used to assess both Big boobs curvy blonde symmetry and ptosis. Lengthening of both this measurement and the distance between the nipple and the fold are both characteristic of advancing grades of ptosis.
The end of the Big boobs curvy blonde, which includes the nipple, may either be flat (a 180 degree angle) or angled (angles lower than 180 degrees). Big boobs curvy blonde ends are rarely angled sharper than 60 degrees. Angling of the end of the Big boobs curvy blonde is caused in part by the ligaments that suspend it, such that the Big boobs curvy blonde ends often have a more obtuse angle when a woman is lying on her back. Big boobs curvy blonde exist in a range of ratios between length and base diameter, usually ranging from 1/2 to 1.
Development
Main article: Thelarche
The development of a girl's Big boobs curvy blonde during puberty is triggered by sex hormones, chiefly estrogen. This hormone has been demonstrated to cause the development of woman-like, enlarged Big boobs curvy blonde in men, a condition called gynecomastia, and is sometimes used deliberately for this effect in male-to-female sex change hormone replacement therapy.
In most cases, the Big boobs curvy blonde fold down over the chest wall during Tanner stage development, as shown in this diagram.[5] It is typical for a woman’s Big boobs curvy blonde to be unequal in size particularly while the Big boobs curvy blonde are developing. Statistically it is slightly more common for the left Big boobs curvy blonde to be the larger.[6] In rare cases, the Big boobs curvy blonde may be significantly different in size, or one Big boobs curvy blonde may fail to develop entirely.
A large number of medical conditions are known to cause abnormal development of the Big boobs curvy blonde during puberty. Virginal Big boobs curvy blonde hypertrophy is a condition which involves excessive growth of the Big boobs curvy blonde, and in some cases the continued growth beyond the usual pubescent age. Big boobs curvy blonde hypoplasia is a condition where one or both Big boobs curvy blonde fail to develop.
In Cameroon, some girls are subjected to Big boobs curvy blonde ironing to stunt Big boobs curvy blonde growth in order to make them less sexually attractive and thus become less likely to become a victim of rape.
Changes
Big boobs curvy blonde with visible stretchmarks.
As Big boobs curvy blonde are mostly composed of adipose tissue, their size can change over time. This occurs for a number of reasons, most obviously when a girl grows during puberty and when a woman becomes pregnant. The Big boobs curvy blonde size may also change if she gains (or loses) weight for any other reason. Any rapid increase in size of the Big boobs curvy blonde can result in the appearance of stretchmarks.
It is typical for a number of other changes to occur during pregnancy: in addition to becoming larger, the Big boobs curvy blonde generally become firmer, mainly due to hypertrophy of the mammary gland in response to the hormone prolactin. The size of the nipples may increase noticeably and their pigmentation may become darker. These changes may continue during Big boobs curvy blondefeeding. The Big boobs curvy blonde generally revert to approximately their previous size after pregnancy, although there may be some increased sagging and stretchmarks.
The size of a woman’s Big boobs curvy blonde usually fluctuates during the menstrual cycle, particularly with premenstrual water retention. An increase in Big boobs curvy blonde size is a common side effect of use of the combined oral contraceptive pill.
The Big boobs curvy blonde naturally sag through aging, as the ligaments become elongated.
Function
The primary function of mammary glands is to nurture young by producing Big boobs curvy blonde milk. The production of milk is called lactation. (While the mammary glands that produce milk are present in the male, they normally remain undeveloped.) The orb-like shape of Big boobs curvy blonde may help limit heat loss, as a fairly high temperature is required for the production of milk. Alternatively, one theory states that the shape of the human Big boobs curvy blonde evolved in order to prevent infants from suffocating while feeding.[8] Since human infants do not have a protruding jaw like human evolutionary ancestors and other primates, the infant’s nose might be blocked by a flat female chest while feeding.[8] According to this theory, as the human jaw receded, the Big boobs curvy blonde became larger to compensate.[8]
Milk production unrelated to pregnancy can also occur. This galactorrhea may be an adverse effect of some medicinal drugs (such as some antipsychotic medication), extreme physical stress or endocrine disorders. If it occurs in men it is called male lactation. Newborn babies are often capable of lactation because they receive the hormones prolactin and oxytocin via the mother's bloodstream, filtered through the placenta. This neonatal liquid is known colloquially as witch's milk.
Sexual role
Big boobs curvy blonde play an important part in human sexual behavior. They are one of most visible female secondary sex characteristics, and play an important role in sexual attraction of partners, and pleasure of the individual. On sexual arousal Big boobs curvy blonde size increases, venous patterns across the Big boobs curvy blonde become more visible, and nipples harden. During sexual intercourse it is common practice to press or massage Big boobs curvy blonde with hands. Oral stimulation of nipples and Big boobs curvy blonde is also common. Some women can achieve Big boobs curvy blonde orgasms. In the ancient Indian work the Kama Sutra, marking Big boobs curvy blonde with nails and biting with teeth are explained as erotic[9].
Other suggested functions
Zoologists point out that no female mammal other than the human has Big boobs curvy blonde of comparable size, relative to the rest of the body, when not lactating and that humans are the only primate that has permanently swollen Big boobs curvy blonde. This suggests that the external form of the Big boobs curvy blonde is connected to factors other than lactation alone.
One theory is based around the fact that, unlike nearly all other primates, human females do not display clear, physical signs of ovulation. This could have plausibly resulted in human males evolving to respond to more subtle signs of ovulation. During ovulation, the increased estrogen present in the female body results in a slight swelling of the Big boobs curvy blonde, which then males could have evolved to find attractive. In response, there would be evolutionary pressures that would favor females with more swollen Big boobs curvy blonde who would, in a manner of speaking, appear to males to be the most likely to be ovulating.
Some zoologists (notably Desmond Morris) believe that the shape of female Big boobs curvy blonde evolved as a frontal counterpart to that of the buttocks, the reason being that whilst other primates mate in the rear-entry position, humans are more likely to successfully copulate by mating face to face, the so-called missionary position. A secondary sexual characteristic on a woman’s chest would have encouraged this in more primitive incarnations of the human race, and a face on encounter may have helped found a relationship between partners beyond merely a sexual one.[10]
Cultural status
In art, religion, and legend
Edouard Manet, “Blonde Woman With Bare Big boobs curvy blonde”
Historically, Big boobs curvy blonde have been regarded as fertility symbols, because they are the source of life-giving milk. Certain prehistoric female statuettes—so-called Venus figurines—often emphasised the Big boobs curvy blonde, as in the example of the Venus of Willendorf. In historic times, goddesses such as Ishtar were shown with many Big boobs curvy blonde, alluding to their role as protectors of childbirth and mothering. The legendary tribe of Amazons bared their Big boobs curvy blonde, and in some accounts removed one Big boobs curvy blonde to allow better combat and archery.
Some religions afford the Big boobs curvy blonde a special status, either in formal teachings or in symbolism. Islam forbids public exposure of the female Big boobs curvy blonde.[11] In Christian iconography, some works of art depict women with their Big boobs curvy blonde in their hands or on a platter, signifying that they died as a martyr by having their Big boobs curvy blonde severed; one example of this is Saint Agatha of Sicily. In Silappatikaram, Kannagi tears off her left Big boobs curvy blonde and flings it on Madurai, cursing it, causing a devastating fire.
In practice
Big boobs curvy blonde are secondary sex characteristics and sexually sensitive. Bare female Big boobs curvy blonde can elicit heightened sexual desires from men and women. Cultures that associate the Big boobs curvy blonde primarily with sex (as opposed to with Big boobs curvy blondefeeding) tend to designate bare Big boobs curvy blonde as indecent, and they are not commonly displayed in public, in contrast to male chests. Other cultures view female toplessness as acceptable, and in some countries women have never been forbidden to bare their chests; in some African cultures, for example, the thigh is highly sexualised and never exposed in public, but the Big boobs curvy blonde is not taboo. Opinion on the exposure of Big boobs curvy blonde is often dependent on the place and context, and in some Western societies exposure of Big boobs curvy blonde on a beach may be acceptable, although in town centres, for example, it is usually indecent. In some areas, the prohibition against the display of a woman’s Big boobs curvy blonde generally only restricts exposure of the nipples.
Women in some areas and cultures are approaching the issue of Big boobs curvy blonde exposure as one of sexual equality, since men (and pre-pubescent children) may bare their chests, but women and teenage girls are forbidden. In the United States, the topfree equality movement seeks to redress this imbalance. This movement won a decision in 1992 in the New York State Court of Appeals—“People v. Santorelli”, where the court ruled that the state’s indecent exposure laws do not ban women from being bareBig boobs curvy blondeed. A similar movement succeeded in most parts of Canada in the 1990s. In Australia and much of Europe it is acceptable for women and teenage girls to sunbathe topless on some public beaches and swimming pools, but these are generally the only public areas where exposing Big boobs curvy blonde is acceptable.
When Big boobs curvy blondefeeding a baby in public, legal and social rules regarding indecent exposure and dress codes, as well as inhibitions of the woman, tend to be relaxed. Numerous laws around the world have made public Big boobs curvy blondefeeding legal and disallow companies from prohibiting it in the workplace. Yet the public reaction at the sight of Big boobs curvy blondefeeding can make the situation uncomfortable for those involved.

Clothing
Since the Big boobs curvy blonde are flexible, their shape may be affected by clothing, and foundation garments in particular. A brassiere (bra) may be worn to give additional support and to alter the shape of the Big boobs curvy blonde. There is some debate over whether such support is desirable. A long term clinical study showed that women with large Big boobs curvy blonde can suffer shoulder pain as a result of bra straps,[12] although a well fitting bra should support most of the Big boobs curvy blonde’ weight with proper sized cups and back band rather than on the shoulders.
Plastic surgery
Plastic surgical procedures of the Big boobs curvy blonde include those for both cosmetic and reconstructive surgery indications. Some women choose these procedures as a result of the high value placed on symmetry of the human form, and because they identify their femininity and sense of self with their Big boobs curvy blonde.
After mastectomy (the surgical removal of a Big boobs curvy blonde, usually to treat Big boobs curvy blonde cancer) some women undergo Big boobs curvy blonde reconstruction, either with Big boobs curvy blonde implants or autologous tissue transfer, using fat and tissues from the abdomen (TRAM flap) or back (latissiumus muscle flap).
Big boobs curvy blonde reduction surgery is a common procedure which involves removing excess Big boobs curvy blonde tissue, fat, and skin with repositioning of the nipple-areolar complex (NAC). Cosmetic procedures include Big boobs curvy blonde lifts (mastopexy), Big boobs curvy blonde augmentation with implants, and procedures that combine both elements. Implants containing either silicone gel or saline are available for augmentation and reconstructive surgeries. Surgery can repair inverted nipples by releasing ductal tissues which are tethering. Big boobs curvy blonde lift with or without reduction can be part of upper body lift after massive weight loss body contouring.
Any surgery of the Big boobs curvy blonde carries with it the potential for interfering with future Big boobs curvy blondefeeding,[13][14][15] causing alterations in nipple sensation, and difficulty in interpreting mammography (xrays of the Big boobs curvy blonde). A number of studies have demonstrated a similar ability to Big boobs curvy blondefeed when Big boobs curvy blonde reduction patients are compared to control groups where the surgery was performed using a modern pedicle surgical technique.[16][17][18][19] Plastic surgery organizations have generally discouraged elective cosmetic Big boobs curvy blonde augmentation surgery for teenage girls as the volume of their Big boobs curvy blonde tissue may continue to grow significantly as they mature and because of concerns about understanding long-term risks and benefits of the procedure.[20] Big boobs curvy blonde surgery in teens for reduction of signifigantly enlarged Big boobs curvy blonde or surgery to correct hypolasia and severe asymetry is considered on a case by case basis by most surgeons.
