16
Q

Source of menstrual fluid

A

endometrium of the uterus

17
Q

fertilization of ovum occurs in

A

Fallopian tube

18
Q

General term for primary reproductive organs is

A

gonads

19
Q

Role of the reproductive system

A

produce gametes and combine to reproduce

20
Q

Ovaries produce which hormones

A

estrogen and progesterone

21
Q

Fallopian tubes

A

site of fertilisation

22
Q

3 layers of the uterus

A

perimetreum (outermost), myometrium (smooth muscle) and endometrium (sheds monthly)

23
Q

Oogenesis

A

Production of eggs in which the primary ovum matures

24
Q

difference between male and female fertility

A

Females have lifetime supply of eggs at birth which declines while males continue to produce sperm from puberty until death

25
Q

Spermatogenesis

A

sperm production, end product is 4 sperm

26
Q

sperm contains how many chromosomes?

A

23

27
Q

erection is under

A

parasympathetic control

28
Q

Ejaculation is under

A

sympathetic control

29
Q

LH

A

luteinising hormone

30
Q

FSH

A

follicle stimulating hormone

31
Q

GnRH

A

Gonadotropin-releasing hormone

32
Q

Role of GnRH

A

secreted by the hypothalamus, controls the menstrual cycle, stimulates the release of LH and FSH from the anterior pituitary

33
Q

Role of LH

A

Spike in LH triggers ovulation and promotes formation of corpus luteum

34
Q

Corpus luteum IF fertilization occurs

A

continues to produce progesterone, developing the endometrium to thicken

35
Q

Corpus luteum if fertilization does not occur

A

degrades, progesterone and estrogen decrease, GnRH, FSH and LH rise and new cycle begins

36
Q

Menstrual phase

A

first 5 days of cycle

37
Q

Pre-ovulatory phase

A

Days 6 - 13

38
Q

Ovulation

A

day 14

39
Q

Post-ovulatory phase

A

days 15 - 28
