Flashcards in Chapter 19 Deck (37):
1

Sperm cells are stored primarily in the

epididymides.

2

Undifferentiated spermatogenic cells are called

spermatogonia

3

The last fluid to be expelled from the urethra during ejaculation comes from the

seminal vesicles.

4

Male reproductive functions are controlled mainly by hormones from the hypothalamus, and

ANTERIOR pituitary gland and TESTES.

5

The hormone responsible for the development and maintenance of male secondary sexual characteristics is

testosterone

6

The female structure that corresponds to the male penis is the

clitoris

7

The hormone mainly responsible for the development and maintenance of female secondary sexual characteristics is

estrogen

8

About the time of ovulation, the anterior pituitary gland releases a relatively large quantity of

LH

9

The tubular portion of the uterus that extends downward into the upper part of the vagina is the

cervix

10

Menopausal females often experience unpleasant symptoms, such as “hot flashes,” as a result of

an 1. INCREASE in gonadotropin concentration and a 2. DECREASE in estrogen concentration.

11

The most commonly used oral contraceptives contain

synthetic ESTROGEN and PROGESTERONE

12

Which of the following is (are) the most reliable form of contraception?

oral contraceptives

13

Which of the following structures are unpaired?

prostate gland

14

In females, what structure is located immediately anterior to the vagina?

pubic symphysis

15

The interstitial cells of the testes produce

androgens

16

The cell commonly called the egg, or ovum, is more correctly called

a SECONDARY oocyte.

17

Fertilization normally occurs in the

uterine tube.

18

In a male, an indirect inguinal hernia occurs when an intestinal loop protrudes into the

VAGINAL process.

19

If the testes fail to descend, a male is infertile because sperm cell formation is prevented by

relatively high internal body temperature.

20

A Pap smear is used to detect the presence of abnormal cells in the

cervix

21

Compared to males who train for endurance events, females who train for such events typically

maintain a higher percentage of body fat.

22

Women athletes sometimes experience disturbances in their menstrual cycles because of

DECREASED synthesis of ESTROGENS.

23

Following ovulation, a human egg cell can survive approximately

24 hours.

24

One of the more common causes of female infertility is failure of ovulation due to hyposecretion of hormones from the

ANTERIOR pituitary gland.

25

Which of the following terms is correctly defined?

cryptorchidism-

failure of testes to descend into scrotum

26

The epididymis is a _____ and it functions to _____ .

tightly coiled tube on the outside of the testis;

store immature sperm as they mature

27

The amount of testosterone in the blood is increased by

1. LH causing the interstitial cells to release 2. TESTOSTERONE.

28

In the menstrual cycle, estrogen functions to _____ , whereas progesterone functions to _____ .

stimulate UTERINE WALL DEVELOPMENT; stimulate the uterine lining to become more glandular

29

The first step in oogenesis is a

PRIMARY oocyte divides to form a secondary oocyte and a first polar body.

30

Egg cells are transported in the female reproductive tract by the _____ , whereas sperm are transported in the male reproductive tract by the _____ .

action of ciliated epithelium in the UTERINE TUBES;

movements of their tails

31

Sperm cells are produced by the germinal epithelial cells that line the

seminiferous tubules.

32

The secretions of the prostate gland function to

neutralize acid semen.

33

In females, egg cell production begins

before birth.

34

The movement of an egg down a uterine tube is aided by

ciliary action.

35

A(n) _________ is held in position by the broad ligament, suspensory ligament, and ovarian ligament.

ovary

36

FSH stimulates a __________ to start the maturation process.

primordial follicle

37

_________ can result in the formation of fibrous tissue around the ovaries and can prevent ovulation or obstruct the uterine tubes.

Endometriosis
