Hormones from Ch. 6

Question 1

Progesterone

Answer 1

Endocrine gland: Ovary (secreted by corpus luteum)
Function: Promotes thickening and maintenance of endometrium
Feedback: Inhibits FSH and LH secretion (negative feedback)

Question 2

Estrogen

Answer 2

Endocrine gland: Ovary (secreted by corpus luteum)

Function:
* Stimulates repair of endometrium
* Stimulates increase in FSH receptors on ovary cells (puberty?)

Feedback:
* Blood concentration falls during menstruation
* Causes reduced FSH secretion (negative feedback)
* Causes increased LH secretion (positive feedback) during follicle development/before ovulation

I think estrogen is also secreted by other methods (during sex determination and puberty onset) but must check

Question 3

FSH (Follicule Stimulating Hormone)

Answer 3

Endocrine gland: Pituitary
Function: Stimulate follicule development (and production of estrogen by follicule)
Feedback:
* Secretion inhibited by estrogen and progesterone (negative feedback)
