breastfeeding mother
Don't know?
Where does breast tissue Along the breast line
normally develop? - located from under the arms down to the groin
1. In utero
What are the 3 stages of early
2. First 2 months of life
breast development?
3. Puberty
Breast development during - Estrogen: Induces Ductal System development
menstruation - Progesterone: Induces Lobular-Alveolar development
What is Lactogenesis? The initiation of milk production
, How many stages of 4
Lactogensis are there?
What stages of Lactogenesis 1 and 2
occur during pregnancy?
Ductal and Lobular-Alveolar systems grow at an accelerated rate
(influenced by hormones)
Lactogenesis 1 - breasts enlarge
- high progesterone levels cause an increase in alveoli
- colostrum begins to produce in the alveoli
When does Lactogenesis 1 around 16 weeks
occur?
The placenta is released from the uterus and progesterone
levels drop
Lactogenesis 2
- this causes the alveolar cells to begin to release milk and allows
them to continue to produce more milk
How long does Lactogenesis 2 2-4 days
last?
- Upper Inner
- Lower Inner

- Tail of Spence
What are the 2 types of breast - Parenchyma: ductal and lobular-alveolar structures
tissue and what are they - Strom: connective tissue (fat, vascular, nerve, lymphatic)
composed of?
Small cavity where milk is produced and stored
What is an Alveolus
- made of epithelial cells
What are Alveoli? multiple alveolus
What is the Intra-lobular duct? Connects a lobule to the lactiferous ducts
What is a Mammary Lobule? 10-100 alveoli combined together
What are Lactiferous Ducts? connects mammary lobules/intra-lobular ducts to the nipple

What surrounds the breast
Lymph Tissue
tissue?
Vascular Network
Myoepithelial Cells
They surround the alveolus and
What is the purpose of the contract (like a muscle)
Myoepithelial cells? - pushes milk out into the ducts
- supplies nutrients, materials, hormones to each alveolus for
What is the purpose of the
milk production
Vascular Network surrounding
- supplies hormones to the myoepithelial cells for ejection of
breast tissue?
milk
