CBC Lactation Physiology & Anatomy 2

Question 1

What is the primary hormonal trigger for the onset of lactogenesis II after birth?

Accepted Answer

The rapid drop in progesterone after delivery of the placenta

Answer

Delivery of the placenta causes progesterone to fall, removing its inhibition of prolactin's milk-producing action.

Question 2

A mother on day 5 postpartum reports no breast fullness and heavy bleeding with clots. Which condition should the counselor suspect may be delaying her milk coming in?

Accepted Answer

Retained placental fragments

Answer

Retained placental tissue keeps progesterone elevated, which can delay lactogenesis II.

Question 3

Which mechanism best explains why a full breast slows its own rate of milk synthesis?

Accepted Answer

A whey protein called feedback inhibitor of lactation (FIL) accumulates

Answer

FIL accumulates in retained milk and locally down-regulates milk production, an autocrine control.

Question 4

What is the main function of the Montgomery glands on the areola?

Accepted Answer

Secreting an oily substance that lubricates the nipple and provides a scent cue for the infant

Answer

Montgomery glands secrete a protective, antibacterial lubricant whose scent may help guide the newborn to the breast.

Question 5

Which structures provide the primary suspensory support for breast tissue?

Accepted Answer

Cooper's ligaments

Answer

Cooper's ligaments are fibrous bands that connect the breast to the skin and underlying fascia.
