When does the breast begin to develop in utero? - ANSWER: 4th week of gestation
Where does the primitive milk streak develop - ANSWER: Bilaterally from the axilla
to the groin
By the 5th week gestation the milk streak becomes what? - ANSWER: Mammary Milk
Ridge (or milk line)
Thickening and inward growth into the chest wall continues during what weeks
gestation? - ANSWER: 7-8 weeks gestation
Between weeks 12 and 16 gestation specialized cells differentiate into what? -
ANSWER: Smooth muscles of the nipple and areola
What forms the mammary pit? - ANSWER: Lactiferous ducts and their branches open
into a shallow epithelial depression
What creates an inverted nipple? - ANSWER: When the Mammary pit fails to elevate
What is witches milk? - ANSWER: After birth, a neonate's mammary tissue (under the
influence of maternal hormones) might recreate colostral like fluid
At what age do the primary and secondary ducts grow and divide and form the
terminal end buds that become the alveoli? - ANSWER: 10-12 years old
When does complete development of mammary function occur? - ANSWER: During
pregnancy
What is superficial fiscia? - ANSWER: Fibrous tissue beneath the skin
Where is the breast located? - ANSWER: In the superficial fascia between the second
rib and sixth intercostal space
What are the two major divisions of the breast? - ANSWER: Parenchyma and Stroma
What makes up the Parenchyma? - ANSWER: Ducts, lobes, and aveoli
What are alveoli? - ANSWER: Small sacs where milk is secreted
,What makes up the Stroma? - ANSWER: Connective tissue, fat tissue, blood vessels,
nerves, and lymphatics.
What is Cooper's Ligament? - ANSWER: Suspensory ligament that are the fibrous
connections between the inner side of the breast skin and pectoral muscles. Help to
shape the breasts
What does the nipple contain? - ANSWER: 15-25 milk ducts, smooth muscle fibers,
sebaceous and apocrine sweat glands, and dense innervations of sensory nerve
endings
What are Montgomery Tubercles? - ANSWER: Sebaceous glands in the areola
surrounding the nipple
What do the Montgomery Tubercles secrete? - ANSWER: Oily secretions (lipoid fluid)
to keep the areola and the nipple lubricated and protected
What artery(s) supply blood to the breast? - ANSWER: Internal mammary artery
(60%) and lateral thoracic artery (30%)
Where does the lymphatic system of the breast drain excess fluids from tissue space,
bacteria and cast off cells? - ANSWER: Auxiliary lymph node
Where does the nerves of the breast mainly branch from? - ANSWER: 4th, 5th, and
6th intercostal nerve
What nerve supplies the greatest amount of sensation to the areola? - ANSWER: 4th
intercostal nerve
What part of the breast is most sensitive? - ANSWER: The areola followed by the
general skin of the breast, and then the nipple which is least sensitive.
What percent of breast milk is carbohydrates? - ANSWER: Approximately 7%
What are the six infant behavioral "states" - ANSWER: Crying, active alert, quiet
alert, drowsy, active sleep, and quiet sleep
Milk components that protect the infant/lactating breast actively bind ______,
preventing their passage through the permeable infant _____ _____ - ANSWER:
pathogens
gut mucosa
How does the infant get the antibodies produced by mom? - ANSWER: antibodies
are produced in moms blood, targeted SIgA which is transported across the
mammary secretory cells and released in the milk.
, What is sIgA? - ANSWER: Immunoglobulin A is an antibody that coats mucosal
surfaces to prevent adherence and penetration by pathogens
What are the most common food allergies? - ANSWER: 1. Cow's milk protein
2. Eggs
3. Peanuts
4. Tree nuts
5. Fish
6. Shellfish
7. Soy
8. Wheat
What are the common symptoms of food allergies? - ANSWER: 1. Eczema
2. Hives
3. Digestive or respiratory problems (e.g. mucus or blood in the stool)
The infant uses their _____ to draw in the nipple and ____ it in the mouth -
ANSWER: Lips
Stabilize
What is weak lip tone? - ANSWER: Hypotonic lips result in the inability to seal lips
around the breast impacting the amount of suction created
What is a sucking blister? - ANSWER: friction abrasions resulting from retracted lips
or a labial frenulum that restricts the lips from flanging
What does weak lip tone look like? - ANSWER: Milk spilling, smacking sound
(breaking suction), infant tires faster due to increased work of the feedings even
though they aren't efficient feedings
Things to look for when assessing the lips: - ANSWER: Seal/maintain seal around the
breasts, normal lip tone, stretchy labial frenulum, no breaks in suction, no milk
spilling
What do fat deposits in the cheeks help provide? - ANSWER: structural support to
stabilize nipple in the mouth
Does low/weak tone cause the infant to have higher or lower levels of suction -
ANSWER: lower levels of suction
What does Hypotonia mean? - ANSWER: Low tone
What does it mean if an infant has thing cheeks due to reduced fat pads? - ANSWER:
That the infants intraoral space is larger than normal, forcing them to create a larger
vacuum to generate and sustain suction. So the work for a feeding increases
What does the dancer's hand help with? - ANSWER: Cheek stability
