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.
[1] [2] Mammary alveoli are the site of milk production and storage in the mammary gland. [1] [2] Mammary alveoli cluster into groups called mammary lobules, and each breast may contain 15 to 20 of these lobules. [1] [2] The lobules drain milk through the lactiferous ducts out of the nipples. [1] [2]
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 ...
Breast engorgement occurs in the mammary glands due to expansion and pressure exerted by the synthesis and storage of breast milk. It is also a main factor in altering the ability of the infant to latch-on. Engorgement changes the shape and curvature of the nipple region by making the breast inflexible, flat, hard, and swollen.
The mammary ridge is primordial for the mammary glands on the chest in humans, and is associated with mammary gland and breast development.. In human embryogenesis, the mammary ridge usually appears as a narrow, microscopic ectodermal thickening during the first seven weeks of pregnancy and grows caudally as a narrow, linear ridge. [1]
Hypermagnesemia is an electrolyte disorder in which there is a high level of magnesium in the blood. [3] Symptoms include weakness, confusion, decreased breathing rate, and decreased reflexes. Hypermagnesemia can greatly increase the chances of adverse cardiovascular events. [1] [3] Complications may include low blood pressure and cardiac ...
Sir James Murray. Sir James Murray (1788–1871) was an Irish physician, whose research into digestion led to his discovery of the stomach aid Milk of Magnesia in 1809. He later studied in electrotherapy and led the research into the causes of cholera and other epidemics as a result of exposure to natural electricity.
