1. Lactiferous duct

   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. They are also referred to as galactophores, galactophorous ducts, mammary ducts, mamillary ducts or milk ducts.

1. lactiferous duct

   A lactiferous duct is a small tubular structure in the breasts that carries milk from the mammary glands to the nipple during lactation (breastfeeding). There are about 15 to 25 lactiferous ducts in each breast, each serving a separate lobe of the breast and allowing the passage of milk to the nipple, where it is then ready to be fed to a nursing infant.

1. Lactiferous duct

   Lactiferous ducts form a tree branched system connecting the lobules of the mammary gland to the tip of the nipple. They are also referred to as galactophores, galactophorous ducts, mammary ducts, mamillary ducts and milk ducts. They are the structures which carry milk toward the nipple in a lactating female. Lactiferous ducts are lined by a columnar epithelium supported by myoepithelial cells. Within the areola, the lactiferous duct were thought to dilate to form the lactiferous sinus in which supposedly milk accumulates between breastfeeding sessions. However new research suggests that lactiferous sinus does not exist. When a woman is not lactating, the lactiferous duct is frequently blocked by a keratin plug. This plug prevents bacteria from entering the duct in non-lactating women. The columnar epithelium plays a key role in balancing milk production, milk stasis and resorption. The cells of the columnar epithelium form tight junctions which are regulated by hormones and local factors like pressure and cassein content. Prolactin and/or placental lactogen are required for tight junction closure while progesterone is the main hormone preventing closure before birth.
