SECTION 1: BREASTFEEDING PHYSIOLOGY AND HORMONES
Q1. What are the two major hormones of lactation, and where are they secreted
from?
A. Estrogen and progesterone from the ovaries
B. Oxytocin and prolactin from the pituitary gland
C. Thyroxine and cortisol from the thyroid and adrenal glands
D. Growth hormone and insulin from the pancreas
Correct Answer: B
Rationale: Oxytocin and prolactin are the two primary hormones of lactation, both
secreted from the pituitary gland. Oxytocin is released from the posterior pituitary and is
responsible for milk ejection (let-down reflex). Prolactin is secreted from the anterior
pituitary and is responsible for milk production. Estrogen and progesterone play
important roles in breast development during pregnancy but are not the primary
hormones of lactation .
Q2. What is prolactin responsible for during lactation?
,A. Milk ejection (let-down reflex)
B. Milk production
C. Breast tissue development during pregnancy
D. Inhibition of milk synthesis
Correct Answer: B
Rationale: Prolactin is the primary hormone responsible for milk production
(lactogenesis). When the infant suckles, nerve signals travel to the hypothalamus,
triggering the anterior pituitary to release prolactin into the bloodstream. Prolactin then
travels to the breast, where it stimulates milk-producing cells (alveoli) to produce milk .
Q3. What triggers the shift from Lactogenesis I to Lactogenesis II?
A. Increased estrogen production
B. Prolactin surge during labor
C. Delivery of the placenta and subsequent drop in progesterone
D. Oxytocin release during the first feeding
Correct Answer: C
Rationale: The shift from Lactogenesis I (colostrum production during pregnancy) to
Lactogenesis II (secretory activation, or "milk coming in") occurs when the placenta is
delivered, causing a dramatic drop in progesterone levels. This allows prolactin to bind
to receptor sites in the breast, initiating copious milk secretion. This typically occurs 2–5
days postpartum .
Q4. What is oxytocin primarily responsible for in lactation?
A. Milk production
B. Milk ejection (let-down reflex)
C. Breast growth during pregnancy
D. Suppressing lactation during pregnancy
Correct Answer: B
, Rationale: Oxytocin causes the myoepithelial cells surrounding the alveoli to contract,
pushing milk out of the milk-producing cells and through the ductal system. This is
known as the milk ejection reflex or let-down reflex. Prolactin, not oxytocin, is
responsible for milk production .
Q5. Which of the following is NOT one of the three mechanisms that trigger
oxytocin release?
A. Conditioned response (baby's smell, touch, or cry)
B. Nipple stretching from proper latch
C. Infant hand massage on the breast
D. Prolactin surge during feeding
Correct Answer: D
Rationale: The three mechanisms that trigger oxytocin release are: (1) conditioned
response—the mother's brain associates sensory cues like the baby's smell, touch, or cry
with feeding; (2) nipple stretching from a proper latch; and (3) infant hand massage on
the breast. Prolactin surge does not trigger oxytocin release; rather, prolactin and
oxytocin work through different pathways .
Q6. How do prolactin levels behave between nursing sessions and during nursing?
A. Levels rise between sessions and decrease during nursing
B. Levels remain constant at all times
C. Levels go down between nursing sessions and rise during nursing
D. Levels are highest in the morning regardless of feeding
Correct Answer: C
Rationale: Prolactin levels decrease between nursing sessions and rise during nursing in
response to nipple stimulation. Infrequent nursing leads to lower baseline prolactin
levels and a reduced surge even with the same amount of nipple contact. This is why
frequent feeding is essential for establishing and maintaining milk supply .
