Certified Breastfeeding Counselor Exam
Where does breast tissue normally develop? Correct Answer: Along the breast line
- located from under the arms
... [Show More] down to the groin
What are the 3 stages of early breast development? Correct Answer: 1. In utero
2. First 2 months of life
3. Puberty
Breast development during menstruation Correct Answer: - Estrogen: Induces Ductal System development
- Progesterone: Induces Lobular-Alveolar development
What is Lactogenesis? Correct Answer: The initiation of milk production
How many stages of Lactogensis are there? Correct Answer: 4
What stages of Lactogenesis occur during pregnancy? Correct Answer: 1 and 2
Lactogenesis 1 Correct 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? Correct Answer: around 16 weeks
Lactogenesis 2 Correct 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? Correct Answer: 2-4 days
What are the 5 main areas of the breast? Correct 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? Correct Answer: - Parenchyma: ductal and lobular-alveolar structures
- Strom: connective tissue (fat, vascular, nerve, lymphatic)
What is an Alveolus Correct Answer: Small cavity where milk is produced and stored
- made of epithelial cells
What are Alveoli? Correct Answer: multiple alveolus
What is the Intra-lobular duct? Correct Answer: Connects a lobule to the lactiferous ducts
What is a Mammary Lobule? Correct Answer: 10-100 alveoli combined together
What are Lactiferous Ducts? Correct Answer: connects mammary lobules/intra-lobular ducts to the nipple
Breast Anatomy Correct Answer:
What surrounds the breast tissue? Correct Answer: Fat
Nerves
Lymph Tissue
Vascular Network
Myoepithelial Cells
What is the purpose of the Myoepithelial cells? Correct Answer: They surround the alveolus and contract (like a muscle)
- pushes milk out into the ducts
What is the purpose of the Vascular Network surrounding breast tissue? Correct Answer: - supplies nutrients, materials, hormones to each alveolus for milk production
- supplies hormones to the myoepithelial cells for ejection of milk
What is the purpose of fat surrounding breast tissue? Correct Answer: protection
support
provides space for growth
What purpose do nerves serve in the breasts? Correct Answer: Intercostal nerves 3, 4 and 5 deal with breast tissue
- innervation to the nipple tells the brain to produce oxytocin when breast feeding
- emptying of the alveolus tells the breast to make more milk
What are Montgomery's Tubercles? Correct Answer: Glands that secrete an antibacterial-like substance that protects the nipples and areola.
- found on the nipple and areola
- enlarge during pregnancy
Lactogenesis 3 Correct Answer: also known as galactopoiesis
- the resupply of mature milk that occurs when milk is removed from the breast
When does Lactogenesis occur? Correct Answer: day 10-14 postpartum
- when mature milk is established
- lasts until mom is ready to wean from breastfeeding
Lactogenesis 4 Correct Answer: involution
- milk production is decreased by apoptosis of the milk making epithelial cells
What are the 2 main hormonal influences of breastfeeding? Correct Answer: Prolactin and Oxytocin
What is the job of Prolactin? Correct Answer: Milk production
Where is prolactin released? Correct Answer: the anterior pituitary gland into the blood stream to the alveoli
What is the main inhibitor of prolactin? Correct Answer: progesterone
When is prolactin released? Correct Answer: When the placenta detaches, progesterone levels decrease and prolactin levels increase
What are some other purposes of prolactin? Correct Answer: - keeps alveoli glued together
- inhibits ovulation [Show Less]
