Unit 8 Study guide Flashcards
Which anatomical structures are involved in lactation
Mammary glands
Lactiferous duct
areola
myoepithelial cells
connective tissue
cooper’s ligament
adipose tissue
Describe the mammary glands
Around the time of puberty:
Develop in female only
Function of mammary gland
to secrete milk to nourish infant
(contains the milk)
Main function of the Lactiferous duct
attach to the mammary gland and help to drain milk to the nipple and areola
what is the Areola
Dark area of breast
it’s dark because baby is born without good eyesight so it help baby find their food source
Where is the Myoepithelial cells
They lines the mammary glands
Function of the myoepithelial cells
Contracting cells
Contract to eject the milk out through the lactiferous duct
Function of connective tissue
Support all the structures in breast
Main connective tissues in breast
collagen
elastin
Function cooper’s ligament
helps to anchor the connective tissue to the breast walls
What is the adipose tissue
Forms part of the breast structure
Which hormones are responsible for milk production and releast
Prolactin
Oxytocin
progesterone
When is oxytocin released
Released from the posterior pituitary due to
suckling
massaging breast
seeing, hearing, touching, smelling infant
it is responsible for the stimulation of “let down”
contraction of myoepithelial cell
It is responsible for ilk release
It provides a sense of calm and relaxation and increases bonding with the infant.
What is the role of progesterone in the production of milk?
It inhibits the prolactin to not make milk…all the time.
Progesterone drops when the placenta is deliver so the prolactin can be released to make milk
Major Components of breast milk
Nutrients
Bioactives
Comensal bacteria
