Breastfeeding Flashcards
(12 cards)
Mature milk changes from the beginning to the end of a feeding. Describe the differences between foremilk and hindmilk
foremilk, is watery, translucent, and rich in lactose and protein. Its purpose is to quench the infant’s thirst.
Hindmilk is delivered toward the end of a feeding. It is opaque, creamy, and rich in fat, and serves to satisfy the infant’s appetite.
compare protein, fat and glucose content of colostrum and mature breast milk
colostrum: high in protein but contains less fat and glucose than mature breast milk
how long without breastfeeding/pumping does it take for the milk supply to end?
Once breastfeeding is stopped for approximately 1 week, any remaining milk will be reabsorbed; in most cases, no more will be produced, even if suckling or pumping is resumed.
Clusters of alveoli that drain to a common duct are called ???; the lactating female has ???(number) of ???organized radially around the nipple
Clusters of alveoli that drain to a common duct are called LOBULES; the lactating female has 12–20 lobules organized radially around the nipple
Breast alveoli are balloon-like structures lined with milk-secreting ??? cells, or lactocytes, that are surrounded by a net of contractile ??? cells.
Breast alveoli are balloon-like structures lined with milk-secreting CUBOIDAL cells, or lactocytes, that are surrounded by a net of contractile MYOEPITHELIAL cells.
The small bumps of the areola (the darkened skin around the nipple) are called ??? glands. What is their purpose?
Montgomery
They secrete oil to cleanse the nipple opening and prevent chapping and cracking of the nipple during breastfeeding.
Mammary glands are modified sweat glands. The non-pregnant and non-lactating female breast is composed primarily of adipose and collagenous tissue, with mammary glands making up a very minor proportion of breast volume.
What happens during pregnancy to the structure of the mammary glands?
the existing ducts expand and branch extensively in pregnancy due to oestrogen and growth hormone
And alveoli bud from the ducts to be ready to produce milk, due to progesterone, hPL and prolactin
how much higher is peak prolactin in pregnancy compared to pre-pregnancy?
10 - 20 times higher
what website did I learn all this stuff about breastfeeding from?

delayed onset of lactogenesis is defined as…
onset >72 hours after delivery and appears to occur more often with preterm delivery and maternal obesity, and may be predicted by markers of metabolic health
the most abundant protein in human colostrum is…
casein, I think!! (according to the given answers)
the micellar casein : whey protein ratio is 40:60, but there are multiple types of whey protein (lactalbumin, lactoferrin, IgA, albumin) so perhaps casein overall is the more abundant single protein
