These variations in the number or structure of the mammaryapparatus (mammarium) have become doubly interesting in the light of recent research in comparative anatomy.
The mammary glands which serve this purpose are interesting in so many ways that we may devote a few lines to them here.

The many well-ascertained cases of various male mammals giving milk, show that their rudimentary mammary glands retain this capacity in a latent condition.
The mammary glands and nipples, as they exist in male mammals, can indeed hardly be called rudimentary; they are merely not fully developed, and not functionally active.
The possession by male mammals of functionally imperfect mammary organs is, in some respects, especially curious.
The female often differs from the male in having organs for the nourishment or protection of her young, such as the mammary glands of mammals, and the abdominal sacks of the marsupials.

The young are nourished for a time by milk, or an analogous fluid, secreted by the mammary glands of the mother.

A white fluid secreted by the mammary glands of female mammals for the nourishment of their young, consisting of minute globules of fat suspended in a solution of casein, albumin, milk sugar, and inorganic salts.
Thus, there can be little doubt that the mammary gland was as apparently useless in the remotest male mammalian ancestor of man as in living men, and yet it has not disappeared.
A similar, but still stronger, argument may be based upon the existence of teats, and even functional mammary glands, in male mammals.
The transverse lines indicate the changes in the principal levels: the head, the mammary glands, and the bust (Fig.
The tape measure should completely encircle the thorax in a horizontal plane passing through the mammary papillae.
The buttons of the thoracimeter are applied on a level with the mammary papillae, along the axillary lines (vertical lines descending from the centre of the arm-pits).

The first fluid secreted by the "breast" (mammary gland) after confinement.
The secretory fibers convey the impulse to the cells of the glands and excite the activity of the gland, and its particular product is secreted or evolved, as, for instance, milk in the mammary gland.

Not less than sixty-five to seventy-five per cent of all cancers in women occur in atrophying organs, the uterus and mammary glands.
The mammary glands are typical glands of external secretion.
Now, if in the castrated male is transplanted an ovary, the positive characteristics of the female are evoked, such as enlarged mammary glands, and a tendency to secretion of milk.
This new-comer is the secretion of the activated breasts, the mammary glands.
What seems to happen in fact, is this: the corpus luteum secretion stimulates the dormant cells of the mammary glands, formed during puberty, but latent until the advent of pregnancy.

The vitellus is directly secreted from the arteries, but the albumen from an enteroidal sac or the oviduct, which is finally converted into mammary glands.
The Ornithorynchus is a furred animal, and this would suffice to bring it among the Aistheseozoa, were we even to deny it mammary organs.
If the existence of mammaryorgans be doubtful, as in the Ornithorynchus, the hairs are in that case perfectly distinct.
During pregnancy the mammary glands are in immediate sympathy with the growing reproductive organs of the pelvis; consequently a genuine physiologic enlargement commences in these organs from the beginning of gestation.
The probable signs are: mammary changes, abdominal enlargement, changes in the neck of the womb, and certain changes which are felt on bimanual examination.
Ribbert, again, cut out the mammary gland of a young rabbit and transplanted it into the ear; five months after the rabbit bore young and the gland secreted milk freely.
Mironoff found that, when the mammary gland is completely separated from the central nervous system, secretion, though slightly diminished, still continued.

The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "mammary" in a variety of sentences. We hope that you will now be able to make sentences using this word.
