ANSWERS WITH COMPLETE
SOLUTIONS 100% CORRECT!!!
Where does breast tissue normally develop in the body?
✔✔ Answer: Along the “milk line,” which extends from the underarm area down
toward the groin
What are the three main stages of early breast development?
✔✔ Answer:
1. In utero
2. First 2 months after birth
3. Puberty
How does breast development change during the menstrual cycle?
✔✔ Answer:
Estrogen stimulates development of the ductal system
Progesterone promotes lobular-alveolar development
What is lactogenesis?
✔✔ Answer: The process of initiating milk production
How many stages of lactogenesis are there?
✔✔ Answer: 4
What stages of Lactogenesis occur during pregnancy? -ANSWER ✔✔1 and 2
,Lactogenesis 1 -ANSWER ✔✔Ductal and Lobular-Alveolar systems grow at an
accelerated rate (influenced by hormones)
- breasts enlarge
- high progesterone levels cause an increase in alveoli
- colostrum begins to produce in the alveoli
When does Lactogenesis 1 occur? -ANSWER ✔✔around 16 weeks
Lactogenesis 2 -ANSWER ✔✔The placenta is released from the uterus and
progesterone levels drop
- this causes the alveolar cells to begin to release milk and allows them to continue
to produce more milk
How long does Lactogenesis 2 last? -ANSWER ✔✔2-4 days
What are the 5 main areas of the breast? -ANSWER ✔✔- Upper Inner
- Lower Inner
- Upper Outer
- Lower Outer
- Tail of Spence
What are the 2 types of breast tissue and what are they composed of? -ANSWER
✔✔- Parenchyma: ductal and lobular-alveolar structures
- Strom: connective tissue (fat, vascular, nerve, lymphatic)
, What is an Alveolus -ANSWER ✔✔Small cavity where milk is produced and
stored
- made of epithelial cells
What are Alveoli? -ANSWER ✔✔multiple alveolus
What is the Intra-lobular duct? -ANSWER ✔✔Connects a lobule to the lactiferous
ducts
What is a Mammary Lobule? -ANSWER ✔✔10-100 alveoli combined together
What are Lactiferous Ducts? -ANSWER ✔✔connects mammary lobules/intra-
lobular ducts to the nipple
Breast Anatomy -ANSWER ✔✔
What surrounds the breast tissue? -ANSWER ✔✔Fat
Nerves
Lymph Tissue
Vascular Network
Myoepithelial Cells
What is the purpose of the Myoepithelial cells? -ANSWER ✔✔They surround the
alveolus and contract (like a muscle)
- pushes milk out into the ducts
