SECTION A: Breastfeeding Physiology & Anatomy
1. The primary hormone responsible for milk production in lactating women is:
A. Oxytocin
B. Prolactin
C. Prolactin
D. Estrogen
Explanation: 👀 ** Prolactin stimulates the alveolar cells in the breast to produce milk;
oxytocin is responsible for milk ejection.
2. Which hormone triggers the milk let-down reflex?
A. Prolactin
B. Oxytocin
C. Progesterone
D. Cortisol
Explanation: 👀 ** Oxytocin causes contraction of myoepithelial cells, pushing milk from
alveoli through ducts.
,3. The functional unit of the breast that produces milk is the:
A. Lobule
B. Alveolus
C. Ductule
D. Areola
Explanation: 👀 ** Alveoli are small sac-like structures where milk is synthesized and
stored.
4. Colostrum is produced primarily during:
A. First week postpartum
B. First few days after birth
C. First month postpartum
D. Last trimester
Explanation: 👀 ** Colostrum is the initial thick, yellowish milk rich in antibodies and
nutrients, produced in the first 2–5 days.
5. Which part of the breast contains the largest number of milk-producing alveoli?
A. Nipple
B. Areola
C. Lobes
D. Cooper’s ligaments
Explanation: 👀 ** Each lobe contains multiple lobules, each with numerous alveoli for
milk production.
6. Milk ejection (let-down) is inhibited by:
A. Stress and pain
B. Prolactin
,C. Suckling
D. Oxytocin
Explanation: 👀 ** Stress, pain, or anxiety can inhibit oxytocin release, delaying milk flow.
7. The hormone responsible for ductal growth during pregnancy is:
A. Progesterone
B. Prolactin
C. Estrogen
D. Oxytocin
Explanation: 👀 ** Estrogen promotes ductal proliferation, preparing the breast for
lactation.
8. True or False: Milk volume is determined solely by breast size.
A. True
B. False
Explanation: 👀 ** Milk production depends on demand (suckling) and hormonal
regulation, not breast size.
9. The areola contains sebaceous glands that:
A. Produce milk
B. Lubricate the nipple during breastfeeding
C. Protect against bacteria
D. Stimulate prolactin
Explanation: 👀 ** Montgomery glands secrete oils to protect and lubricate nipples.
10. Lactogenesis II refers to:
, A. Onset of copious milk production 2–3 days postpartum
B. Colostrum formation
C. Involution of the breast
D. Milk ejection reflex
Explanation: 👀 ** Lactogenesis II occurs 48–72 hours postpartum, when milk volume
increases significantly.
11. Suckling stimulates the release of:
A. Prolactin only
B. Oxytocin only
C. Both prolactin and oxytocin
D. Estrogen
Explanation: 👀 ** Prolactin stimulates milk production; oxytocin causes ejection.
12. The primary source of immunoglobulins in colostrum is:
A. Alveolar cells
B. Fat globules
C. Maternal plasma
D. Lactocytes
Explanation: 👀 ** IgA antibodies are transferred from maternal blood to colostrum,
providing passive immunity.
13. Lactose is synthesized in:
A. Ductules
B. Alveolar cells
C. Nipple
D. Areola
