Asexual Reprod. Daughter cells have 2n instead of “n” daughter cells like in Meiosis.
Sexual Reprod. Daughter cells have “n”. 23+23 somatic = 46 chromosomes = Zygote.
male and female
Allows for penetration into vagina. Parasympathetic control
Expels Semen. Sympathetic control
allow the penis to become stiff so that it can enter the female vagina to deliver sperm.
Forms male gametes (sperm)
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
Secondary Spermatocytes’s daughter cells
Mature sex cells with an acrosome (helmet for nucleus of head), midpiece (contain mitochondria), and tail for swimming
Male- Stimulates spermatogenesis
Female- release estrogen
Male- Stimulates release of testosterone
Female- release androgens to create estrogen
Synthesis of proteins. Enhances stimulation of spermatogenesis and increase in accessory organ sizes
What testosterone is sometimes converted to in the prostate. Same effects as testosterone though.
What testosterone is sometimes converted to in the brain, bone, and fat. Same effects as testosterone
Preps uterus for ovum fertilization
What allows child birth contractions
Process of female gamete (ovum) formation
Spermatogonia equivalent. Diploid stem cells (by mitosis) Then turn into Primary Ooocytes
First meiotic division. Spermatocyte equivalent. BUT P.O only occurs in fetus. Lifetime supply at birth.
Only completed upon fertilization
Female reproductive cell (gamete)
Haploid cell formed with oogenesis
Maturation of ovarian follicle with immature oocytes
have a single layer of squamous pre-granulosa cells surrounding a primary oocyte. Can grow into Primary Follicle
have multiple layers of granulosa cells surrounding a primary oocyte.
FHS hormone rage. Ovary wall ruptures to released secondary oocyte. Released from ovary down fallopian tube for fertilization
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.
Corpus Luteum is active during this phase
supplies the high levels of progesterone and estrogens that characterize the luteal phase. If no pregnancy, CL degenerates
Scar that forms from corpus luteum after pregnancy doesn’t happen.
Fluid-filled sac where ovum develops before ovulation
Uterus sheds deepest part of of endometrium. Ovarian hormones are at all time low. This is where menstruation occurs.
Endometrium rebuilds itself.
Most constant timewise. Endometrium prepares for an embryo to implant. Increase levels of progesterone
Formation of gametes (meiosis)
Primary reproductive organ (testis, ovaries)
