Origins
The standard model of the human breast is largely based on anatomical dissections carried out on cadavers by Astley Cooper and published in 1840 under the title “Anatomy of the Breast”.
This model is based on wax casts and dissections prepared by Cooper. The casting procedure introduced several artefacts. The injection of coloured wax into milk duct openings at the nipple inflated those ducts, giving the impression that near the nipple they expand into milk storage sacs called lactiferous sinuses. Also, in order to illustrate the milk ducts, Cooper – who had likened them to the intertwined roots of a tree – laid them out in an ordered manner for the artist to draw. This ordered lay-out has been copied into anatomy diagrams ever since.
Until 2005, Cooper's results had never been corroborated by modern investigative methods. Consequently, Cooper's model still underlies most practitioners understanding of the lactating human breast.

Famous quotes containing the word origins:
“Grown onto every inch of plate, except
Where the hinges let it move, were living things,
Barnacles, mussels, water weeds—and one
Blue bit of polished glass, glued there by time:
The origins of art.”
—Howard Moss (b. 1922)
“The settlement of America had its origins in the unsettlement of Europe. America came into existence when the European was already so distant from the ancient ideas and ways of his birthplace that the whole span of the Atlantic did not widen the gulf.”
—Lewis Mumford (1895–1990)
“The origins of clothing are not practical. They are mystical and erotic. The primitive man in the wolf-pelt was not keeping dry; he was saying: “Look what I killed. Aren’t I the best?””
—Katharine Hamnett (b. 1948)
