Question 1

Human Chorionic gonadotropin hormone (hCG)

Answer 1

Maintains corpus luteum (oestrogen & progesterone until week 10 of pregnancy) Detected in pregnancy test associated with pregnancy-associated with pregnancy induced nausea
Produced in trophoblast (outer layer of blastocyst)

Question 2

Gonadotropin Releasing Hormone (GFnRH)

Answer 2

Stimulates release of luteinising hormone (LH) & follicle stimulating hormone (FSH) from Anterior Pituitary Gland
Produced in Hypothalamus-inhibited by rising oestrogen and progesterone levels

Question 3

Follicle Stimulating Hormone (FSH)

Answer 3

Maturation of Graafian follicle which produced oestrogen
Produced in Anterior Pituitary Gland

Question 4

Luteinising Hormone (LH)

Answer 4

Maturation of Graafian follicle leading to ovulation
Produced in Anterior Pituitary Gland

Question 5

Progesterone (Steroid hormone)

Answer 5

thickens endometrium for implantation
Breast formation
relaxes smooth muscle during pregnancy
Increases body temperature
Changes to cervical mucus
Produced in ovaries-corpus luteum
Trophoblast
increased levels inhibitt prolactin

Question 6

Human Placental Lactogen (hPL)

Answer 6

Insulin antagonsit, colostrum production and breast growth
Produced in Trophoblast

Question 7

Oestrogen (steroid)

Answer 7

breast growth
Increasing uterine vascularisation of endometrium
swelling + softening of connective tissue
Ovaries-corpus luteum

Question 8

Oxytocin

Answer 8

love hormone, uterine contractions, crucial role in childbirth, lactation, and pair bonding
Produced in hypothalamus
Stored in post pituitary glands, uterus

Question 9

Relaxin

Answer 9

Relax pelvic girdle, softens cervix
Produced in placenta, corpus luteum, deciduu

Question 10

Prolactin

Answer 10

Inhibits ovulation, alveolar development, lactogenesis and suppressing ovulation
Produced in Anterior Pituitary.
