Answer 2

Follicle-stimulating hormone (FSH) and luteinising hormone (LH) are pituitary hormones. Oestrogen and progesterone are ovarian hormones. Role of pituitary and ovarian hormones:

Hormone Functions

FSH i. Stimulates the ovarian follicles to secrete oestrogen ii. Stimulates the proliferation of the endometrium of the uterine wall iii. Stimulates the maturation of Graafian follicles

LH i. Stimulates the release of ovum ii. Develops the corpus luteum and in the secretion of progesterone iii. Maintains pregnancy

Oestrogen i. Controls the changes in the secondary sex organs in the first half of the menstrual cycle ii. Stimulates growth, maturation and function of the secondary sex organs iii. Repairs the damaged tissues of the uterus and fallopian tubes after menstruation iv. Stimulates the maturation of ova and the development of the uterine lining and mammary glands

Progesterone i. Facilitates the preparation of the endometrium for implantation ii. Inhibits the contraction of the uterus and the development of new follicles
