Q

ovarian cycle

A
  • follicular - day 1-14 where immature follicles mature as a result of FSH. oocyte grows in follicle, ovum discharged into fimbria of fallopian tube
  • luteal phase - days 15-28 where ovum leaves the follicle, ovum remains in the ampulla if fertilized, reaches uterus 72-96 hrs after release then implants into the endometrium and secretes human chorionic gonadotropin (hCG) OR if no fertilization, corpus leteum degenerates

Q

Menstrual Cycle

A
  • menstrual - shedding some endometrial cells
  • proliferative - endometrial cells enlarge and thicken due to increased estrogen, peaking just before ovulation, cervical mucous is more elastic/thin/clear
  • secretory - progesterone causes marked swelling of epithelium, vascularity of uterus increases to provide nourishing bed for implantation
  • ischemic - begins if implantation doesn’t occur, estrogen and progesterone levels decrease, corpus leteum degenerates
