Hormones

Question 1

Oestrogen

Answer 1

Produced under the influence of FSH until the degeneration of the corpus luteum then the levels fall. Responsible for female characteristics, proliferation of endometrium and cervical and vaginal mucus.

Question 2

Progesterone

Answer 2

Produced by the corpus luteum under the influence of LH. Enriched blood supply to endometrium, rise in body temperature 0.5 degrees, breast changes during menstruation

Question 3

Relaxin

Answer 3

Maximum level between 38-42 weeks of pregnancy. Originates in the corpus luteum. Relaxes pelvis, softens cervix and suppresses uterine contractions, reduces oxytocin release

Question 4

Follicle Stimulating Hormone (FSH)

Answer 4

Causes Graafian follicles to develop and enlarge, stimulates oestrogen

Rising oestrogen causes a surge of LH and FSH prior to ovulation. Progesterone inhibits a new rise unless there is no pregnancy and the corpus luteum degenerates about 14 days after ovulation

Question 6

Prolactin

Answer 6

If produced in excessive amounts it will inhibit ovulation. Assists in production of breast milk.
