1
Q

Mitosis

A

Asexual Reprod. Daughter cells have 2n instead of “n” daughter cells like in Meiosis.

2
Q

Meiosis

A

Sexual Reprod. Daughter cells have “n”. 23+23 somatic = 46 chromosomes = Zygote.
PMAT

3
Q

Gonads

A

male and female

4
Q

Erection

A

Allows for penetration into vagina. Parasympathetic control

5
Q

Ejaculation

A

Expels Semen. Sympathetic control

6
Q

corpora cavernosa

A

allow the penis to become stiff so that it can enter the female vagina to deliver sperm.

7
Q

Spermatogenesis

A

Forms male gametes (sperm)

8
Q

Spermatogonia

A

Mitosis cell division of sperm into 2 daughter cells. Of the two, one becomes Primary Spermatocyte to make four sperm. The other goes for Secondary Spermatocyte in dividing pool

9
Q

Spermatids

A

Secondary Spermatocytes’s daughter cells

10
Q

Spermatozoa/Sperm

A

Mature sex cells with an acrosome (helmet for nucleus of head), midpiece (contain mitochondria), and tail for swimming

11
Q

FSH

A

Male- Stimulates spermatogenesis

Female- release estrogen

12
Q

LH

A

Male- Stimulates release of testosterone

Female- release androgens to create estrogen

13
Q

Testosterone

A

Synthesis of proteins. Enhances stimulation of spermatogenesis and increase in accessory organ sizes

14
Q

DTH

A

What testosterone is sometimes converted to in the prostate. Same effects as testosterone though.

15
Q

Estradiol

A

What testosterone is sometimes converted to in the brain, bone, and fat. Same effects as testosterone

16
Q

Progesterone

A

Preps uterus for ovum fertilization

17
Q

Oocyte

A

Immature egg

18
Q

Myometrium

A

What allows child birth contractions

19
Q

Ooogenesis

A

Process of female gamete (ovum) formation

20
Q

Oogonia

A

Spermatogonia equivalent. Diploid stem cells (by mitosis) Then turn into Primary Ooocytes

21
Q

Primary Oocytes

A

First meiotic division. Spermatocyte equivalent. BUT P.O only occurs in fetus. Lifetime supply at birth.

22
Q

Secondary Ooctyes

A

Only completed upon fertilization

23
Q

Ova

A

Female reproductive cell (gamete)

24
Q

Polar Body

A

Haploid cell formed with oogenesis

25
Q

Folliculogenesis

A

Maturation of ovarian follicle with immature oocytes

26
Q

Primordial Follicles

A

have a single layer of squamous pre-granulosa cells surrounding a primary oocyte. Can grow into Primary Follicle

27
Q

Secondary Follicles

A

have multiple layers of granulosa cells surrounding a primary oocyte.

28
Q

Ovulation

A

FHS hormone rage. Ovary wall ruptures to released secondary oocyte. Released from ovary down fallopian tube for fertilization

29
Q

Follicular Phase

A

vesicular follicles secrete increasing amounts of estrogens and one of these follicles is selected as the dominant follicle. Phase lasts from the first to the fourteenth day of the ovarian cycle, at which point ovulation typically occurs.

30
Q

Luteal Phase

A

Corpus Luteum is active during this phase

31
Q

Corpus Luteum

A

supplies the high levels of progesterone and estrogens that characterize the luteal phase. If no pregnancy, CL degenerates

32
Q

Corpus Albicans

A

Scar that forms from corpus luteum after pregnancy doesn’t happen.

33
Q

Graafian Follicle

A

Fluid-filled sac where ovum develops before ovulation

34
Q

Menstrual Stage

A

Uterus sheds deepest part of of endometrium. Ovarian hormones are at all time low. This is where menstruation occurs.

35
Q

Proliferative Stage

A

Endometrium rebuilds itself.

36
Q

Secretory Stage

A

Most constant timewise. Endometrium prepares for an embryo to implant. Increase levels of progesterone

37
Q

Gamete

A

Sex cell

38
Q

Gametogenesis

A

Formation of gametes (meiosis)

39
Q

Gonad

A

Primary reproductive organ (testis, ovaries)

40
Q

Zygote

A

Fertilized Egg
