1.Different stages of breast development
- Embryogenesis
- Mammogensis
- Lactogenesis 1
- Lactogenesis 2
- Lactogenesis 3
: Embryogenesis: mammary gland devo 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.
2.Estrogen
Progesterone
Prolactin
Oxytocin
TSH
: 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
3.Tail of spence: What is it, symptoms
: Mammary gland tissue that extends to axillary area, connected to
milk ducts –> can cause swollen armpits & mastitis
4.Accessory tissue: Where are they found? Can they lactate
?: Diagonal line from axilla to groin area
– can lactate & undergo malignant change
5.Flat nipples
Pseudo inverted nipple
Retracted nipple
Inverted nipple
- possible issues, short shank, solutions
: 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
