a natural extension of pregnancy
breastfeeding
period of milk production by the mother’s mammary glads to feed the baby
lactation
a learned behavior
breastfeeding
feeding of breastmilk only
exclusive breastfeeding
process of milk synthesis and secretion of mammary gland
lactogenesis
highly specialized secretory glands, composed of glandular tissues, connective tissues, and fat
female breast/
mammary glands
basic structure of breast
milk-producing cells (glandular epithelium)
duct system - embedded in connective tissue and fat
Mature breast weighs approx. ____ g

postpartum amenorrhea
LAM
lactation amenorrhea method
LAM is more than 98% effective if the following criteria are met:
Amenorrhea (no menses)
;
Exclusive breastfeeding
The infant is less than 6 months of age
synthesis of milk components
milk secretion
milk passes along duct system
milk propulsion or ejection
MILK PRODUCTION STAGES
1 milk secretion
2 milk propulsion or ejection
HORMONES OF LACTATION
- prolactin
- oxytocin
- estrogen
- growth hormones, chorionic somatomammotrophin
- ACTH, tyroxine, thyrotrophine-releasing hormone
REFLEXES
- prolactin reflex
- let-down reflex
stimulates milk production
inhibits ovulation
prolactin
stimulate milk ejection
promotes uterine contraction
oxytocin
inhibits milk production
estrogen
initiation of lactation
growth hormones, chorionic somatomammotrophin
continuation of lactation
ACTH, tyroxine, thyrotrophin-releasing hormone
stimulates the nerve endings in the nipple»_space; stimulates the anterior pituitary gland to release prolactin
sucking
milk-secretion reflex
prolactin reflex
A psychoneuro-hormonal mechanism regulated by CNS
,
Affected by emotional factors; Be inhibited by embarrasment or stress or can be released by the mere thought of the baby;
Process of streams of milk flowing out of the nipple
let - down reflex
EXPRESSION OF MILK
