Question 1

Galactopoiesis refers to:

Accepted Answer

The maintenance of established milk production

Answer

Galactopoiesis is the ongoing maintenance of milk production after it has been established, dependent on continued suckling and prolactin release.

Question 2

Feedback Inhibitor of Lactation (FIL) is a whey protein that:

Accepted Answer

Decreases milk synthesis when milk accumulates in the breast

Answer

FIL is a local autocrine inhibitor that slows milk synthesis when milk accumulates in the alveoli, preventing engorgement injury.

Question 3

A lactating mother follows a strict vegan diet. Her exclusively breastfed infant is at highest risk for deficiency of which nutrient?

Accepted Answer

Vitamin B12

Answer

Vitamin B12 is found almost exclusively in animal products; vegan mothers have low B12 in milk, putting their infants at risk for deficiency and neurological damage.

Question 4

The alveoli in the mammary gland are lined primarily with:

Accepted Answer

Lactocytes (secretory epithelial cells)

Answer

Lactocytes are the secretory epithelial cells that synthesize and secrete milk components into the alveolar lumen.

Question 5

Which statement about iron in human breast milk is accurate?

Accepted Answer

Iron in human milk is highly bioavailable (approximately 50%) due to lactoferrin

Answer

Although human milk contains relatively low iron concentrations, its bioavailability is approximately 50% due to lactoferrin and other binding proteins, compared to only 4-7% from formula.
