Question

Choose the correct sequence with respect to the stages of changes that the breast undergoes in human female at different stages of life.

• A. mammogenesis $\to$ lactogenesis $\to$ galactokinesis $\to$ galactopoiesis $\to$ involution
• B. lactogenesis $\to$ mammogenesis $\to$ galactokinesis $\to$ galactopoiesis $\to$ involution
• C. lactogenesis $\to$ mammogenesis $\to$ galactogenesis $\to$ galactopoiesis $\to$ involution
• D. lactogenesis $\to$ mammogenesis $\to$ galactogenesis $\to$ involution $\to$ galactopoiesis

Answer 1

The correct option is A mammogenesis $\to$ lactogenesis $\to$ galactokinesis $\to$ galactopoiesis $\to$ involution

Lactation is the process of milk secretion from the mammary glands of a mother after childbirth. The milk thus produced provides nutrition and immunity to the young one.

Mammogenesis- development of mammary glands to a functional state, starts from birth to puberty and continues in pregnancy as well.

Lactogenesis- synthesis and secretion of milk from breast alveoli, which occurs in mid-pregnancy.

Galactokinesis- ejection of milk outside the breast.

Galactopoiesis - maintenance of lactation.

Involution - regression and atrophy post lactation.
