Different stages of breast development
- Embryogenesis
- Mammogensis
© 2025 Assignment Expert
- Lactogenesis 1
- Lactogenesis 2
- Lactogenesis 3 —ANS: Embryogenesis: mammary gland devo
Guru01 - Stuvia
while 5 wk embryo
Mammogenesis: @ puberty, estrogen influences growth of ducts
and buds
Lactogenesis 1: completion of mammary development from
placenta stimulation; ducts stimulated + colostrum secretion at 16
wks
Lactogenesis 2: Secretory activation when placenta out --> decr
progesterone --> inc prolactin --> inc milk supply
Lactogenesis 3: Milk removal --> mature milk prod; Infant sucking=
^ oxytocin= let down.
Estrogen
Progesterone
Prolactin
Oxytocin
TSH —ANS: Estrogen - ^ during pregnancy; stim growth in ductile
system
Progesterone - ^ during pregnancy; stim alveoli and lobes

Prolactin - frm ant pituitary gland; lands on prolactin receptor sites
to start milk prod
Oxytocin - from post pituitary gland; cause LETDOWN
TSH - ^ responsiveness of mammary cells
Tail of spence: What is it, symptoms —ANS: Mammary gland tissue
that extends to axillary area, connected to milk ducts --> can
cause swollen armpits & mastitis
Accessory tissue: Where are they found? Can they lactate? —
ANS: Diagonal line from axilla to groin area
- can lactate & undergo malignant change

Flat nipples
Pseudo inverted nipple
Retracted nipple
Guru01 - Stuvia
Inverted nipple
- possible issues, short shank, solutions —ANS: Flat - remains flat
after stimulation or retract with compression (short shank) --> diff
w/ latch
Pseudo - seems inverted but erect upon stimulation
Retracted - retracts upon stimulation
Inverted - retracted at rest &s stimulation
Nipple shield may help.
Hypoplasia, what is it? —ANS: Underdevelopment, insufficient
glandular tissue --> can lead to insufficient milk
Active let down
- How is milk ejected into ducts from alveoli? aka let down
- signs of let down
- postions that are helpful for let down —ANS: Myoepitheal cells
encase the aveoli, contract in response to oxytocin. In response to
sucking oxytocin increases
