  5. During circumcision, what part of the penis is removed? (medical term for foreskin)
  6. fertilization
    Occurs the moment that generic material of a sperm combines with that of an ovum to form a fertilized egg (zygote)
  7. Where does fertilization occur?
    Uterine tubes
  8. Ovulation
    the ejection of an egg from the ovary
  9. Name the three layers of the uterine wall from inner to outer
    • endometrium
    • myometrium
    • perimetrium
  10. body of the uterus
    major portion of the uterus
  11. fundus of the uterus
    superior region above the entrance of the uterine tubes
  12. cervix of the uterus
    narrow outlet, protruding into the vagina
  13. Menstrual cycle
    Cyclic changes that the endometrium goes through month after month in response to hormonal changes
  14. proliferative phase of the menstrual cycle
    • endometrial blood supply increases
    • endometrium thickens again
  15. Secretory phase of the menstrual cycle
    • If fertilization occurs, perfect environment to nourish
    • If fertilization does not occur, sets the stage for menses
  16. embryo (time period)
    from fertilization until week 8
  17. fetus (time period)
    from week 9 until birth
  18. How long can the egg survive in order for the conception to take place?
  19. zygote
    • fertilized egg

    • expulsion
    • placental
  24. Dilation stage (of labor) - events
    • contractions push baby against cervix
    • cervix softens, and effaces (thins)
    • amnionic sac ruptures
    • lasts 6-12 hours
  25. Expulsion stage (of labor) - events
    • from full dilation to delivery
    • urge to push
    • typically 50 minutes (can be 20 min - 2 hrs)
  26. Placental stage (of labor) - events
    • about 15 minutes after birth
    • placenta and fetal membranes detach from uterus

    • Strangles the urethra
    • Increases risks of infection
    • Makes urination difficult
  32. What is primary follicle made of? (female)
    • Contains an immature ovum (egg)
    • Egg surrounded by layers of follicle cells
  33. Epididymus (male reproductive tract)
    temporary storage site for sperm
  34. Ductus (vas) deferens (male reproductive tract)
    • from epididymus to the ejaculatory duct
    • Functions to propel sperm into the urethra
  35. Urethra
    • from base of bladder to tip of penis
    • carries both urine and semen
  36. Three regions of the male urethra from bladder the tip of penis

    • membraneous urethra
    • spongy urethra
  37. Prostatic urethra
    region of the urethra surrounded by the prostate gland
  38. Membraneous urethra (male)
    region of the urethra from prostatic urethra to the penis
  39. Spongy (penile) urethra
    • Region of the urethra running within the length of the penis
    • Opens to the exterior of the body
  40. Scrotum
    • a devided sac of skin hanging outside of the body
    • houses the testes
  41. What is the function of the scrotum?
    to keep the testes at about 3o C cooler than the body
  42. Glans penis (of the penis)
    enlarged tip of the penis
  43. prepuce (of the penis)
  44. Ovaries
