Embryogenesis: mammary gland devo while 5 wk embryo
Mammogenesis: @ puberty, estrogen influences growth of ducts
Different stages of breast
and buds
development
Lactogenesis 1: completion of mammary development from
- Embryogenesis
placenta stimulation; ducts stimulated + colostrum secretion at 16
- Mammogensis
wks
- Lactogenesis 1
Lactogenesis 2: Secretory activation when placenta out --> decr
- Lactogenesis 2
progesterone --> inc prolactin --> inc milk supply
- Lactogenesis 3
Lactogenesis 3: Milk removal --> mature milk prod; Infant
sucking= ^ oxytocin= let down.
Estrogen - ^ during pregnancy; stim
growth in ductile system
Progesterone - ^ during pregnancy;
Estrogen stim alveoli and lobes
Progesterone Prolactin - frm ant pituitary gland;
Prolactin lands on prolactin receptor sites to
Oxytocin start milk prod
TSH Oxytocin - from post pituitary gland;
cause LETDOWN
TSH - ^ responsiveness of mammary
cells
Tail of spence: What is it, Mammary gland tissue that extends to axillary area, connected to
symptoms milk ducts --> can cause swollen armpits & mastitis
Accessory tissue: Where are Diagonal line from axilla to groin area
they found? Can they lactate? - can lactate & undergo malignant change
Flat - remains flat after stimulation or retract with compression
Flat nipples
(short shank) --> diff w/ latch
Pseudo inverted nipple
Pseudo - seems inverted but erect upon stimulation
Retracted nipple
Retracted - retracts upon stimulation
Inverted nipple
Inverted - retracted at rest &s stimulation
- possible issues, short shank,
solutions
Nipple shield may help.
Underdevelopment, insufficient glandular tissue --> can lead to
Hypoplasia, what is it?
insufficient milk
, Active let down Myoepitheal cells encase the aveoli, contract in response to
- How is milk ejected into ducts oxytocin. In response to sucking oxytocin increases
from alveoli? aka let down
- signs of let down Tingling, warmth, fullness, dripping, contractions
- postions that are helpful for let
down helpful in australian/saddle
- Fats: most variable, help brain devo, hi in evenings
-Protein: Casein- allows for iron to be absorbed, mature milk.
Whey- hi in colostrum, contains IGA; has lysozyme that kills
bacteria
What is breast milk composed Carbs: creates acidic environment in gut & has lactose that reg
of? milk vol
Vitamins: A,D,E,K,C, thiamin, riboflavin, b's that influenced by
mom.
Minerals: calcium, phosphorus, magnesium, not affected by diet.
+ 88% water
Implants
- compress milk ducts --> impede milk flow --> compromise
reaching max milk vol
Impact of breast surgery on
lactation
Hyaluronic acid injections
- Implants
- no risk of being absorbed in baby's GI tract
- hyaluronic acid injections
- breast reduction
Reduction
- BF might not be possible after
- BF early + stim bm early
Signs of milk transfer Swallowing, air from nose, ca sound, movement seen

Feeding patterns 24-48 hrs & 48 must stimulate breast

Black to green to yellow (by end of first week). Watery and seedy
How does poop transform? at first
Normal urine output Urine output --> 1 diaper per day of life (e.g: 2 day old infant min
of 2 wet diapers)
