Flashcards in Chapter 15: Reproduction Deck (31):
1

Haploid cell that fuses with second haploid cell to effect fertilization and create a zygote.

Gamete

2

Gamete producing organ.

Gonads

3

Male gonads.

Testes

4

Specific location of sperm production.

Seminiferous tubules

5

Gametes that upon fertilization supply chromosomes but not much else.

Sperm

6

Tubes that rhythmically delivers sperm from the epididymis to the urethra during ejaculation.

Vas deferens

7

Source of yellowish fluid that aids in sperm post ejaculation survival and functioning.

Seminal vesicle

8

Contributor of white, alkaline fluid that makes up one half or more of the volume of semen.

Prostate gland

9

Semen delivery organ.

Penis

10

Egg containing spherical clusters of cells where many of these clusters together make up ovaries.

Follicle

11

An unfertilized egg cell that is receptive to fertilization.

Ovum

12

Connecting organ between the ovary and the uterus.

Fallopian tube

13

Location in mammals where fetus gestation occurs.

Uterus

14

Muscular canal separating the lumen of the uterus from that of the vagina.

Cervix

15

The mucous membrane lining of the uterus.

Endometrium

16

Internal female structure directly involved in sexual intercourse and into which sperm is deposited in the course of male ejaculation.

Vagina

17

Female external genetalia.

Vulva

18

Well defined sequence of modifications to the egg-producing anatomy of sexually mature but not pregnant females.

Ovarian cycle

19

Progesterone-secreting structure that is present within ovaries during the secretory phase of the ovarian cycle.

Corpus luteum

20

Well defined sequence of modifications to the embryo-nourishing anatomy of sexually mature but not pregnant female mammals.

Uterine cycle

21

Blood discharge from the vagina associated with shedding of the endometrium.

Menses

22

Time during the uterine cycle of endometrium shedding.

Menstrual phase

23

Time during the uterine cycle of endometrium regeneration.

Proliferation phase

24

Time during the uterine cycle when the corpus luteum is producing progesterone.

Secretory phase

25

Diploid product of gamete fusion.

Zygote

26

Mitotic division during early animal embryonic development.

Cleavage

27

Embryonic product of cleavage that consists of a solid ball of cells.

Morula

28

Hollow ball of cells that forms from the morula during the early embryonic development of mammals.

Blastocyst

29

Blastocyst attachment to the uterine lining.

Implantation

30

The transition from antepartum to postpartum.

Parturition

31

Milk producing organ associated with mammals.

Mammary gland
