Q

uterus involution process
-3 steps

A

-the uterus is returning to the pre-pregnant state!
1. contraction of the uterus
2. autolysis of myometrial cells
3. regeneration of the epithelium

**results from reduction in cell SIZE, not reduction in cell number

Q

Q

Lactation

  2. milk ducts: each contains 4-18 primary milk ducts that converge at the nipple
  3. basic glandular unit: contains 4-18 lobules, each containing alveoli for milk ejection
  4. nipples and areola: become darker during pregnancy
  5. montgomery tubercles: located IN areola; sebaceous glands that provide protective secretion and lubrication to the nipple
63
Q

physiology of lactation
1. mammary changes during pregnancy
2. lactogenesis I
3. lactogenesis II
4. lactogenesis IV

A
  1. mammary changes during pregnancy
  2. lactogenesis I
    -early pregnancy to third day postpartum
    -dependent on HORMONAL changes
    -secretion of small amounts of colostrum: high concentrations of immunoglobulins, oligosaccharides
    -approx. 100 ml of breastmilk produced on pp day 1
  3. lactogenesis II
    -days 2-4 postpartum
    -second stage initiated by: delivery of placenta, decrease in progestin, increase in prolactin
    -VOLUME: increases; no approx. 500 mL on day 4 pp, COPIOUS milk production, “milk coming in”
  4. lactogenesis IV
    -begins between 7-14 days pp
    -mature milk established
    -maintenance of milk supply depends on supply-demand relationship (frequent milk transfer –> suckling stimulated nipple –> sends message to hypothalamus to secrete prolactin and oxytocin –> prolactin stimulates milk production) –> oxytocin is the hormone responsible for stimulating contraction of myoepithelial cells; the contraction of cells causes milk ejection aka “the let-down reflex”
64
