1

14

2 pouches in the female:

Vesicouterine and Rectouterine

15

Pouch in the male:

Rectovesicle

16

Specialized erectile tissue develops from:

Mesoderm

17

Erectile tissue closer to midline:

Right and left BULB

18

Erectile tissue more laterally:

Right and left CRUS

19

Subdivides the cloaca in a rectum and a bladder:

Urogenital diaphragm

20

In the male, right and left bulbs fuse in the midline to form:

21

In the male, right and left crura form:

Corpora cavernosa

22

In the female, the bulbs of the vestibule become:

28

Coelomic space on right and left side of scrotal sac is:

Primarily retroperitoneal

29

Ovaries are secondarily:

Intraperitoneal

30

What passes through inguinal canal?

Spermatic cord, blood vessels out and in

31

What tube gives rise to the uterus?

Paramesonephric duct

32

Paramesonephric duct becomes:

Fallopian tubes

33

Pouch between bladder and uterus:

Vesicouterine

34

Pouch between rectum and uterus:

35

Surrounds the urethra and makes up the head or glans of the penis:

40

Go through meiosis and make sperm cells:

Spermatogenic cells

41

Keep spermatogenic cells alive:

Sustentacular cells

42

Tip of sperm used to penetrate egg:

Acrosomal cap

43

Prostate gland secretes:

44

Cells that secrete testosterone:

47

Erection has a ______ function

Parasympathetic

48

Ejaculation has a ______ function

Sympathetic

49

Orgasm has a ________ function

Sympathetic and parasympathetic

50

Ovaries start:

Retroperitoneal

51

What part of the follicle in a female secretes estrogen and progesterone?

Corpus luteum

52

1st step of uterine cycle

Hypothalamus releases GnRH that stimulates anterior pituitary gland to release FSH and LH

53

What does the hypothalamus release as the first step?

Gonadotropin-releasing hormone

54

2nd step of uterine cycle

FSH stimulates maturation of follicle

55

3rd step of uterine cycle

Follicle produces estrogen;
Builds uterine wall, turns off FSH

56

Where is the biggest spike of LH in the whole cycle?

4th step

57

4th step of uterine cycle

High levels of estrogen stimulates secretion of LH

58

What step of uterine cycle does the egg leave the fallopian tube and become exposed for fertilization?

4th step

59

Ovulation is accompanied by:

LH spike

60

5th step of uterine cycle

Corpus luteum secretes estrogen and progesterone; turns off LH

61

6th step of uterine cycle

Estrogen and progesterone levels drop as corpus luteum degenerates to corpus albicans

62

7th step of uterine cycle

Break down of endometrium; tissue and blood loss is known as menstruation

63

8th step of uterine cycle

Low LH causes secretion of FSH again; cycle repeats itself

64

What hormone does the placenta secrete?

Human Chorionic Gonadotropin

65

What inhibits the corpus luteum from wearing out?

hCG
