Lactiferous ducts are ducts that converge and form a branched system connecting the nipple to the lobules of the mammary gland.When lactogenesis occurs, under the influence of hormones, the milk is moved to the nipple by the action of smooth muscle contractions along the ductal system to the tip of the nipple.
A mammary gland is an exocrine gland in humans and other mammals that produces milk to feed young offspring.Mammals get their name from the Latin word mamma, "breast".The mammary glands are arranged in organs such as the breasts in primates (for example, humans and chimpanzees), the udder in ruminants (for example, cows, goats, sheep, and deer), and the dugs of other animals (for example, dogs ...
A blocked milk duct has the following common symptoms: [2] [3] Low fever and breast infection; Pain in a particular side of the breast; Swollen or tender lump in the breast; Slower milk flow; a small white blister on the nipple called a milk bleb; swelling or redness of the breast; areas of the breast that are hot or warm to touch
In recent years, many researchers have been focused on DCIS: ductal carcinoma in situ, the earliest stage of cancer that in most cases remains in the milk ducts and does not invade other tissues ...
Duct ectasia of the breast, mammary duct ectasia or plasma cell mastitis is a condition that occurs when a milk duct beneath the nipple widens, the duct walls thicken, and the duct fills with fluid. This is the most common cause of greenish discharge. [1] Mammary duct ectasia can mimic breast cancer. It is a disorder of peri- or post-menopausal ...
Breast right after surgical intervention for breast abscess. A breast abscess is a collection of pus that develops in the breast with various causes. [13] During lactation, breast abscess develops only rarely, most sources cite about 0.4–0.5% of breastfeeding women. [7] Known risk factors are age over 30, primiparous (first birth) and late ...
An example of true apocrine glands is the mammary glands, responsible for secreting breast milk. [2] Apocrine glands are also found in the anogenital region and axillae. [3] Apocrine secretion is less damaging to the gland than holocrine secretion (which destroys a cell) but more damaging than merocrine secretion .
A galactocele (also called lacteal cyst or milk cyst) is a retention cyst containing milk or a milky substance that is usually located in the mammary glands. They can occur in women during or shortly after lactation. [1] They present as a firm mass, often subareolar, and are caused by the obstruction of a lactiferous duct.
