Refer the figure of mammary gland with few structures marked as A, B, C and D. Identify the marked structures.
1 Mammary lobe, mammary duct, ampulla and lactiferous duct.
2 Ampulla, mammary duct, lactiferous duct and mammary lobe.
3 Lactiferous duct, mammary lobe, mammary lobe and ampulla.
4 Mammary duct, mammary lobe lactiferous duct and ampulla.
Explanation:
(a) The structures marked in the figure of mammary gland are A-mammary lobe, B-mammary duct C-ampulla, and D-lactiferous duct. The mammary gland is a gland located in the breasts of females that is responsible for lactation. Mammary glands only produce milk after childbirth. Mammary lobe (A) contains clusters of cells called alveoli which secrete milk which is stored in the cavities of alveoli.

Most of the primary follicles in the ovary normally
1 undergo atresia and disintegrate.
2 mature and are ovulated.
3 are lost in the menstrual flow each month.
4 develop throughout the life span.
Explanation:
(a) Although the human female is born with millions of primordial follicles in the ovaries that can give rise to primary, secondary and mature follicles, the vast majority become atretic. Although a number of follicles begin to develop each month, only one primary follicle matures to become the dominant follicle that is ovulated in each monthly ovarian cycle. Approximately 400 mature follicles are ovulated during the reproductive life of the human female.
