Repro test (part 1) Flashcards
Patau (trisomy 13)
missing first sex chromosome & severe life threatening symptoms, therefore cannot survive
Klinefelters
extra “X” chromosone (XXY)
Edwards (trisomy 18)
extra 18th chromosome
Cri Du Chat
missing part of #5, an arm
Turners
affects women, only has 1 “X” chromosome, missing or incomplete
Down syndrome (trisomy 21)
3 #21 chromosomes
Primary follicle
estrogen producing
**primary= first stage of egg maturation
Growing follicle
estrogen producing
second stage
Graafian follicle
estrogen producing
3rd stage
Ruptured follicle
estrogen producing
ovulation, very last stage
Corpus luteum
progesterone producing
after ovulation, ruptured follicle turns into this, which eventually disintegrates
FSH
-anterior pituitary
follicle stimulating hormone by growing and maturing the follicles
LH
-anterior pituitary
luteinizing hormone, triggers ovulation
Estrogen
-ovarian hormone
hormone that causes the appearance of the secondary sex characteristics in young women
*follicles
Progesterone
-ovarian hormone
lasts 10-14 days
produced by the corpus luteum
major effects are exerted during pregnancy, prepares for milk production
*source of progesterone during pregnancy is placenta
Zygote
fertilized egg
Embryo
organism in its early stages of development, first 2 months after conception
Zygote
fertilized egg
Embryo
early stages of development(after zygote)
first 2 months after conception
Ovarian follicle
tiny saclike structures that contain an immature egg
Oocyte
immature egg, surrounded by one or more layers of follicle cells
Antrum
fluid-filled central region
Follicle
*vesicular or Graafian
mature after develoption of the antrum
Ovulation
ejection of mature, developing egg from the ovary
*14th day of the 28 day cycle
Oogenesis
when female gametes are produced, *beginning of an egg
Ovaries
primary female reproductive organs
exocrine products: eggs/ova
endocrine products: estrogen and progesterone
Mensis
(days 1-5)
- endometrium sloughs off
- bleeding 3-5 days
Proliferate
(days 6-14)
- estrogen levels inc. bc of follicle growth
- endometrium heals
- glands form in endometrium
- endometrium blood supply inc.
- LH IS THE OVULATION TRIGGER
Secretory
(days 15-28)
- CL inc. in size = pro. inc
- blood supply inc. to endometrium
- nutrients secreted into uterine cavity to sustain developing embryo until it implants
Fertilization
- embryo produce hormone similar to LH making the CL keep producing progesterone
- pregnancy starts
No fertilization
- CL eventually degenerates by days 25-28 = LH dec.
- ovarian hormones (PRO + EST) dec. at end of cycle-blood vessel kink
- dec. blood/O2/nutrients = tissue death
