Show Answers:

  1. low levels of estrogen
    removes inhibition of fsh and lh
  2. moderate levels of estrogen
    inhibits fsh and lh
  3. High levels of estrogen
    stimulates gnrh and promotes the release of fsh and lh
  4. phase of secondary oocyte
    metaphase II
  5. Amount of DNA in secondary oocyte
  6. corpus hemmorrhagicum
    blood clot that forms after ovulation
  7. GnRH
    causes the release of FSH and LH
  8. FSH
    stimulates initial development if ivarian follicles, helps in the follicle's secretion of estrotgen and inhibin
  9. LH
    helps maturing the dominant follicle, causes the secondary oocyte to be released (ovulation) maintains the corpus luteum (if fertilized)
  10. progesterone only secreted by the...
    corpus luteum
  11. progesterone
    prepares endometrium for implantation
  12. progesterone
    inhibits gnrh and lh
  13. inhibin
    inhibits release of FSH so there is only 1 dominant follicle and the rest die
  14. relaxin
    keeps the uterus relaxed, inhibits contraction of smooth muscle
  15. hCG
    released by the chorion of embryo to maintain the corpus luteum which is releasing progesterone and estrogen to maintain the functional layer
  16. hCS
    prepares mammary glands for lactation, increases protein synthesis, decreases glucose use for ATP production
  17. Corticotropin Releasing Hormone
    establishes time of birth, increases secretion of cortisol
  18. Cortisol
    released later in pregnancy, contributes to surfactant production
  19. most common form of estragen in non preganant female
    12 beta estradiol
  20. form of 12 beta estradiol in pregnant female

    location of spermatogenisis
  22. epididymus
    maturation of sperm takes place here
  23. leydig cells
    secrete testosterone
  24. sertoli cell surface
    where sperm is made
  25. Blood testis barrier
    protects sperm from immune system
  26. spermatogonium
    stem cells from which sperm are produced
  27. LH
    stimulates testosterone secretion
  28. leydig cells have _______ receptor
  29. Sertoli cells have ______ receptor
  30. Nuclei of sertoli cells has ______ receptor
  31. Androgen Binding protein is secreted by____
    sertoli cells
  32. high concentration of testosterone
    spermatogensis occurs
  33. Inhibin
    inhibits release of FSH; controls number of sperm
  34. 5 alpha reductase is located in
    prostate and semincal vesicle
  35. 5 alpha reductase converts __________ to _________
    testosterone; DHT
  36. testosterone
    steroidal hormone that can go through plasma membrane to form a complex with its receptor which is a gene regulator
  37. before birth testosterone...
    stimulates male development of ducts and descent of testis
  38. DHT
    stimulates the development of external ganglia
  39. pill
    synthetic estrogen and progestines thich inhibit fsh and lh so the lh surge can not take place.
