Ch25 study guide (newborn nutrition and feeding) Flashcards
structures in the breast that contain alveoli surrounded by myoepithelial cells
- there are approximately 15-20 of these structures embedded in the fat and connective tissue I teach female breast
lobes
milk-producing cells
alveoli
breast structures that transport milk from the milk-producing cells to the nipple
- they form a complex intertwining network
milk ducts
cells that surround the alveoli
- these cells contract in response to oxytocin, resulting in the milk ejection/let-down reflex
myoepithelial cells
rounded, pigmented section of tissue surrounding the nipple
areola
the process of milk production
lactation (lactogenesis)
the lactogenic hormone secreted by the anterior pituitary gland in response to the infant’s suck and emptying of the breast
prolactin
posterior pituitary hormone that triggers the let-down reflex
oxytocin
reflex response of the nipple when the infant cries, suckles, or rubs against the breast
- this response aids in propelling milk through the milk ducts to the nipple pores
nipple erection reflex
nipple type that remains flat and soft and does not protrude, even when stimulated
inverted
plastic device that can be placed over the nipple and areola to keep clothing off the nipple and put pressure around its base to promote protrusion of the nipple
breast shell
clear yellowish, high protein, antibody rich fluid present in the breasts before the formation of milk
colostrum
breastfeeding problem that is best prevented by utilizing correct breastfeeding techniques
sore nipples
newborn behaviors that indicate hunger and a desire to eat, such as hand-to-mouth movements, rooting, and mouth and tongue movements
feeding cues
reflex triggers by the contraction of myoepithelial cells as a result of oxytocin stimulation
- colostrum, and later milk, is transported to the nipple
let-down or milk-ejection reflex (MER)
