Flashcards in Lab 8 - Reproductive System Deck (46):
1

Define gonads

The primary reproductive organs, which in the female is the ovaries

2

Define germ cells

A cell containing half the number of chromosomes as a somatic cell

A gamete

A cell able to unite with one from the opposite sex to form a baby

3

The purpose of external reproductive organs (female)

1. Enables sperm to enter the body

2. Protects internal genital organs from damage

3. Sexual pleasure

4

External male structures

Penis, scrotum, and testicles

5

Female genital tract

Vagina - Uterus - Fallopian tubes - Ovaries

6

Scrotum function

Production of viable sperm

Kept slightly below body temperature

7

Vas deferens function

Carry ejaculatory sperm

8

Spermatic cord function

Connects lymphatics, nerves, and vessels of the testes to the body

9

Ampulla function

End of the vas deferens - acts as a reservoir for sperm

10

Ejaculatory duct function

Semen passes through during ejaculation

11

Seminal vesicles function

Open into vas deferens and secrete many of the components of semen

12

Prostate function

Secretes milky fluid that activates perm

13

Bulbourethral glands function

Adds fluid to semen during ejaculation

14

Semen function

Consists of sperm and seminal fluid

Buffers the sperm against the acidity of the female vagina

15

Penis function

Delivers sperm to the female reproductive tract

16

Foreskin function

Protects the glans penis

17

Corpus cavernosa function

The two chambers that run the length of the penis

Filled with spongy tissue that can be filled with blood

18

Corpora spongiosum function

Prevents compression of the urethra

19

Function of testes

Produces sperm

20

Tunica albuginea function

Tough fibrous layer that surrounds the corpora cavernous and covers the testicles

21

Seminiferous tubules function

Sperm forming factories

22

Rete testes function

Carries sperm from seminiferous tubules to the efferent ducts

23

Interstitial cells function

Produce testosterone

24

Mons pubis function

Secretes pheromones via oil glands

25

Labia major function

Project the sensitive structures of the vulva

26

Labia minora function

Surround the clitoris, urinary orifice, and vaginal orifice

27

Vestibule function

Where the urinary meatus and vaginal opening meet

28

Perineum function

The area between the anus and scrotum or vulva

29

Clitoris function

Sexual stimulation

30

Precipice of clitoris function

Marks the boundary between mucosa and skin

31

Vagina funciton

extends from vulva to clitoris

32

Cervix function

Attaches vagina to uterus

Produces mucous that helps sperm to fertilize an egg

33

Endometrium function

Thickens during the menstrual cycle in preparation for an egg

34

Fallopian tubes function

Tubes along which eggs travel from ovaries to uterus

35

Fimbriae function

Pulsate and guide ovum to uterus

36

Broad ligament function

Attaches the uterus, fallopian tubes, and ovaries to pelvis

37

Mesometrium function

Mesentery of the uterus

38

Myometrium function

Smooth muscle tissue of the uterus

39

Nipple function

Milk leaves the breasts through the lactiferous ducts

40

Lobes and lobules of mammary glands

Each lobule contains a lactiferous duct

41

Alveoli function

Form cavities in the breasts which are filled with milk secreting cells

42

Lactiferous ducts

Connects nipples to the lobules of the mammary gland

43

What is the purpose of meiosis?

Reduces the normal diploid cells to haploid to create gametes

44

Draw, label, and describe meiosis in a male

46

Draw the stages of the menstrual cycle
