Question 6

Describe the structure and function of the mammary gland.

Answer 6

Parenchyma
- milk-secreting alveolar cells (epithelial cells) eventually form hollow, circular structures called alveoli
- alveoli = fundamental milk-secreting units of the mammary gland

Nipple
- an enlarged area of the epithelium which is the external connection to the internal milk-secreting system
- develops on the surface

As pregnancy progresses, lobules of alveoli develop and fill with secretion (milk); stromal tissue is reduced to thin bands
- Early pregnancy = stoma > alveoli/lobules
- Later pregnancy = alveoli/lobules > stroma

Question 7

Describe the lactation cycle.

Answer 7

Milk production tends to increase for the first 3-4 weeks of lactation and then begins to slowly decline through the end of lactation

Cows are usually dried up after 305-day lactation periods

Neonates are weaned usually 4-5 weeks postpartum

Back pressure of milk within the alveoli gradually inhibits the secretion of milk by the alveolar epithelial cells
- Results in the regression of the alveolar cells and small ducts

Involution requires 4-6 weeks

Within 1-2 months, the secretory (alveoli) and excretory (duct) systems regress and are once again replaced
