Physiology reproductive

  1. purpose of the reproductive system
    continuation of the species and to pass on your genes "the selfish gene concept"
  2. primary sex organs
    gonads produce gamates theres 2 types of gamates eggs and sperm
  3. what hormones do the primary sex organs secrete
    progesterone and estrogen and then androgens
  4. Males scrotum
    3C degrees less then the rest of the body with help from the cremaster muscle that brings the boys up when its cold and down when its warm to not over heat and denature the soldiers
  5. seminal vesicles
    60% of the total volume of a ejaculation, mainly fructose, capacitation begines here which is the beginning of getting the sperm to be able to be mobile
  6. Prostate gland
    secretes a antibiotic (seminalplasmin) that cleans out the urethra before ejaculation. 20-30% volume
  7. seminalplasmin
    the antibiotic that the prostate gland releases to kill the bacteria from the urethra.
  8. interstitial cells
    or cells of leydig creates androgen that then creates testosterone see phone for the picture.
  9. seminiferous tubules
    where sperm production takes place, sertoli cells create the sperm cells.
  10. blood testis barrier
    like the blood brain barrier but found in the seminiferous tubules, the immune system will actually attack the sperm cells if they could since they weren't around when the immune system was learning self.
  11. spermatogenesis
    sperm production, stem cells is called spermatongia goes through mitoesis daughter cells A and B 1 stem cell creates 4 sperm.
  12. spermiogenesis
    the maturation of the sperm cells after they are made (so after spermatogenesis
  13. protease
    dissolves mucus plug in there external os
  14. seminalplasmin
    antibiotic from the prostate gland
  15. prostatic enzyme
    makes the sperm clot up so that it can capacitation 30 minutes after ejaculated it dissolves and the sperm will be all ready to move and fertilize that egg.
  16. fibrinolysin
    breaks down the clot after 30 minutes in the vagina getting used to the environment so that they are capacitation.
  17. Capacitation
    the movement of the sperm
  18. fimbrae
    aren;t indirect contact with the ovaries, they create currents with a pumping action to suck the egg into the fallopian tube when the egg is ready to ovulate
  19. stratum functionalis
    the most superficial layer of the endometrium, this is what is shed every month during menstruation, responds to ovarian hormones, temporary room and board for sperm.
  20. stratum basalis
    2nd layer in the endometrium, its the rejuvenating layer it creates the stratum functionalis. it doesn't respond to ovarian hormones
  21. corpus luteum
    creates the progesterone and estrogen spikes, after the egg is ovulated.
  22. corpus albicans
    the dead corpus luteum that becomes scar tissue
  23. before puberty hormonal regulation
    low estrogen levels inhibit the GnRH from the hypothalamus.
  24. at puberty hormonal regulation
    hypothalamus becomes less sensitive (by either the number of receptors increase or a change in recpetors we dont know for sure) to the same amount of estrogen
  25. leptin levels and regulation
    low percentage of body fat and less menstral cycles big debate if its good or bad to have less or more menstral cycles,
  26. 1st phase of the ovarian cycle
    follicular phase (follibrae is creating that current for ovulation) this is different number of days for all woman
  27. 2nd phase of the ovarian cycle
    luteal phase, this doesn;t differ between woman. if pregnant the corpus luteum stays alive till the babys big enough to take care of the hormones by its self which is 2-3 months. no pregnancy and it lasts 14 days later then dies becomes the corpus albicans
