Chapter 20, Problem 27RA

Summary Introduction

To review:

1. The mechanisms in which the nursing of a baby by the mother leads to lactation.

2. The mechanisms responsible for eliciting the milk-ejection reflex on the sound of a baby crying.

Introduction:

The progesterone hormone stimulates the development of alveolar gland. Progesterone and estrogen prepare the mammary gland for milk production. After parturition, prolactin is responsible for the stimulation of milk production, and oxytocin stimulates the event of milk ejection.
