Keeping Peolpe Healthy: Week Three Flashcards
What is the main sugar in breast milk?
Lactose
What is the first milk made by the breast called?
Colostrum
What antibody is in breast milk?
IgA
What is the function of alpha-lactalbumin, located in breast milk?
Antibacterial and Immunostimulatory properties
What is the function of lactoferrin, located in breast milk?
Binds iron in competition with bacteria products, preventing iron overdoes
What is the function of Oligosaccrahries, located in breast milk?
Encourage the growth of beneficial probiotic organisms in the gut
What is the function of epidermal growth factor, located in breast milk?
Promotes healing
What is the function of neural growth factor, located in breast milk?
Promotes peristalsis development
What can long chain polyunsaturated fatty acids help with?
Brain development
What is Necrotising enterocolitis ?
Necrotising enterocolitis (NEC) is a serious illness in which tissues in the intestine (gut) become inflamed and start to die. This can lead to a perforation (hole) developing, which allows the contents of the intestine to leak into the abdomen (tummy). Formula fed babies are 6-10 times more likely to get this.
When and where is prolactin produced?
This is stimulated from the anterior pituitary gland when the nipple is stimulated.
What is the function of prolactin?
Cause lactocytes to make milk
When and where is oxytocin produced?
This is made in posterior pituitary and stimulated when there is nipple stimulation
What is the function of feedback inhibitor of lactation?
This will build up in the milk and cause lactation to stop.
What are some advantages of bottle feeding?
- longer nights
- separation
- large volumes always available
- same micronutrients
What intercostal spaces does the breast expand to and from?
2nd-6th
What is the pigmented area around the nipple called?
Areolar
What muscle cells surround the alveoli of the breast and help contraction?
Myoepithelial
What is the function of Cooper’s ligaments?
Hold breasts against chest wall
What is the function of the Montgomery glands?
Secrete a lipid fluid that helps lubricate the areolar and protect the nipple
What type of gland is the breast?
Apocrine
What is the epithelium of the nipple?
Keratinized stratified squamous epithelium
What is the breast vascular supply?
Internal thoracic artery
What are the three lymphatic nodes of the breast?
Axillary, Parasternal, Posterior intercostal
What is the passage way of breast milk out of the breast?
Alveoli (contained in the lobule) - lactiferous duct -lactiferous sinus - nipple
What three hormones prepare the alveolar cells to prepare for milk production during pregnancy?
Human placental lactogen, progesterone from the placenta.
Prolactin from the anterior pituitary.
Why is there no milk let-down during pregnancy?
Although there is prolactin stimulating let-down, it is inhibit by the placental progesterone.
What is the difference in the alveolar cells compared to pregnancy and lactation?
Pregnancy: columnar
Milk production: squamous and have microvilli
