RATIONALES | PASS GUARANTEED – A+ GRADED
SECTION 1: LACTATION ANATOMY AND PHYSIOLOGY – Questions 1–12
Q1: Anatomy – Milk Ejection Reflex
The student is reviewing the milk ejection reflex. What triggers the release of oxytocin?
A. Infant sucking at the breast
B. Maternal stress
C. Cold temperatures
D. Formula supplementation
Correct Answer: A
Rationale: Infant sucking stimulates nerve endings in the nipple, sending signals to the
hypothalamus to release oxytocin from the posterior pituitary, causing milk ejection. [100%
CORRECT]
Q2: Physiology – Prolactin Receptors
The student is reviewing prolactin. When do prolactin receptor sites increase?
A. During pregnancy
B. During the first few weeks postpartum with frequent milk removal
C. During menopause
D. During weaning
Correct Answer: B
Rationale: Prolactin receptor sites increase during the first few weeks postpartum with frequent and
effective milk removal, establishing long-term milk supply. [100% CORRECT]
Q3: Anatomy – Lactiferous Sinuses
The student is reviewing breast anatomy. Where are lactiferous sinuses located?
A. Behind the nipple
B. In the alveoli
C. In the lobules
D. In the fatty tissue
Correct Answer: A
Rationale: Lactiferous sinuses are widened areas of the ducts behind the nipple where milk collects
before ejection. [100% CORRECT]
Q4: Physiology – Autocrine Control
The student is reviewing milk regulation. What is autocrine control of milk production?
,2
A. Local regulation of milk production based on milk removal
B. Hormonal regulation from the pituitary
C. Regulation by the infant's weight
D. Regulation by maternal diet
Correct Answer: A
Rationale: Autocrine control (local regulation) adjusts milk production based on how much milk is
removed. The Feedback Inhibitor of Lactation (FIL) plays a key role. [100% CORRECT]
Q5: Physiology – Endocrine Control
The student is reviewing milk regulation. What is endocrine control of milk production?
A. Hormonal regulation by prolactin and oxytocin
B. Local regulation by FIL
C. Regulation by infant demand
D. Regulation by maternal fluid intake
Correct Answer: A
Rationale: Endocrine control involves hormones (prolactin for production, oxytocin for ejection).
Autocrine control is local. [100% CORRECT]
Q6: Anatomy – Myoepithelial Cells
The student is reviewing breast anatomy. What is the function of myoepithelial cells?
A. To contract and eject milk
B. To produce milk
C. To store milk
D. To transport milk
Correct Answer: A
Rationale: Myoepithelial cells surround alveoli and contract in response to oxytocin, ejecting milk
from the alveoli into ducts. [100% CORRECT]
Q7: Physiology – Colostrum Volume
The student is reviewing colostrum. What is the typical volume of colostrum produced per feeding in
the first 24 hours?
A. 1–5 mL
B. 10–15 mL
C. 30–60 mL
D. 60–90 mL
Correct Answer: A
Rationale: Colostrum volume is small (1–5 mL per feeding) in the first 24 hours, matching the
newborn's small stomach capacity. [100% CORRECT]
Q8: Physiology – Mature Milk Volume
The student is reviewing mature milk. What is the typical daily milk intake for a 1-month-old infant?
, 3
A. 150–300 mL
B. 300–500 mL
C. 500–800 mL
D. 800–1000 mL
Correct Answer: C
Rationale: A 1-month-old typically consumes 500–800 mL of breast milk per day, increasing to about
750–800 mL by 6 months. [100% CORRECT]
Q9: Anatomy – Nipple Anatomy
The student is reviewing nipple anatomy. How many nipple pores are typically present?
A. 1
B. 5–10
C. 15–20
D. 20–25
Correct Answer: B
Rationale: The nipple typically has 5–10 openings (lactiferous duct openings), though the number
can vary. [100% CORRECT]
Q10: Physiology – Milk Synthesis Rate
The student is reviewing milk synthesis. What is the rate-limiting step in milk synthesis?
A. Lactose synthesis
B. Fat synthesis
C. Protein synthesis
D. Water transport
Correct Answer: A
Rationale: Lactose synthesis is the rate-limiting step in milk production. Lactose draws water into
the milk. [100% CORRECT]
Q11: Physiology – Breast Milk Composition Changes
The student is reviewing milk composition. How does breast milk composition change during a
feeding?
A. Fat content increases
B. Protein content increases
C. Lactose content increases
D. Water content increases
Correct Answer: A
Rationale: Fat content increases from foremilk to hindmilk during a feeding. Protein, lactose, and
water remain relatively stable. [100% CORRECT]
Q12: Anatomy – Mammary Gland Development
The student is reviewing breast development. When does full mammary gland development occur?
