  1. Day 24 of MC
  2. Estrogen
  3. Secondary follicle
  4. Follicular Phase 1
  5. Proliferation phase
  1. a Implantaion (egg burrows into wall of uterus, endometrium erodes) this takes six to seven days
  2. b (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
  3. c FSH rises initially to stimulate follicle growth. Growing follicle secretes esradiol. Estradiol stimulates GnRH secretion, which stimulates LH and FSH secretion (positive feed back)
  4. d larger 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
  5. e 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)

5 Multiple choice questions

  1. development of uterus (uterus thickens overtime; if no pregnancy then it will become thin again
  2. development of egg/follicle (follicular phase| ovulation| luteal phase) Based on FSH and LH
  3. Fertilization must occur before this day and after ovulation or the egg dies
  4. 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. follicular 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

5 True/False questions

  1. OogenesisOnly 1 egg per cycle (but the egg gets 4X the nutrients) occurs once a month (due to cylcic changes in hormone)


  2. Premenstrual Phaseenodmetrium thickens, breaks down (because blood vessles are cut off) and discharged


  3. Luteal (postovulatory) phaseAfter ovulation LH stimulates follicular/ granulosa cells and the cells multiply and fill the antrum
    Corpus luteum forms from remaining granulosa cells and secretes estradiol, progesterone and inhibin


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


  5. Day 1 of MCovulation
