5 Matching questions

  1. Ovulation
  2. Premenstrual Phase
  3. Proliferation phase
  4. Ischemia
  5. Follicular Phase 2
  1. a FSH and LSH sprike triggers of ovulation. LH induces the primary oocyte and corona radiata leave the ovary
  2. b Endometrium begins wtih one layer called stratum basalis. Deepest layer of uterus, closest to smooth muscle, contains glands adn blood vessels and produces other layers. (Proliferation, Secretory and Premenstrual)
  3. c if NO pregnancy- endometrium degenerates becuase corpus leteum involutes to corpus ablican and no progesterone is produces
  4. d spiral arteries contract so blood stops flowing-> stratum functionalis dies -> menstrual cramps push dead tissue away from the body since its too much for macrophages to handle
  5. e Corona radiata and secondary oocyte leave the ovary. Reamaining follicular/ granulosa cells become corpus luteum

5 Multiple choice questions

  1. Fertilization must occur before this day and after ovulation or the egg dies
  2. FSH rises initially to stimulate follicle growth. Growing follicle secretes esradiol. Estradiol stimulates GnRH secretion, which stimulates LH and FSH secretion (positive feed back)
  3. (secreted from follicles) stimultes growth fo stratum functionalis. Closest to the lumen, lost at the end fo the menstrural cycle and rebuilt during proliferation phase
  4. 4 spermatids per mitotic cycle; occurs all the time
  5. consists of a primary oocyte arrested in meiosis I
    single layer of follicular cells
    follicular cells pass nutrients and chemical signals to oocyte
    Become primary folliceles when follicular/ granulosa cells thicken from squamous to cuboidal shape

5 True/False questions

  1. Menstrual Cylcleenodmetrium thickens, breaks down (because blood vessles are cut off) and discharged


  2. Tertiary folliclefollicular fluid accumulates to form the antrum

    cumulus oophorus: a layer of granulosa cells that covers the oocyte

    corona radiata: innermost layer of cells in the cumulus


  3. Day 24 of MCImplantaion (egg burrows into wall of uterus, endometrium erodes) this takes six to seven days


  4. Secretory Phaseif NO pregnancy- endometrium degenerates becuase corpus leteum involutes to corpus ablican and no progesterone is produces


  5. Secondary folliclelarger oocytes and stratified follicular (granulosa) cells

    zona pellucida: layer of glycoprotein gel secreted by granulosa cells around the oocyte

    theca folliculi: connective tissue forms a fibrous coat
