  1. True or false: Genes on the Y Chromosome iniate testes differentiation.
    True
  2. True or false: All eggs have one X.
    True
  3. XO occurs in about 1/6000 births, small reproductive system, normal intellect.
    Turner Syndrome
  4. YXX in about 1/1500 births, normal male geneitals, feminized elsewhere.
    Klinefelter Syndrome
  5. Defective gene on X renders tissues insensitive to male horomones, have
    XY chromosomes and testes internally, but external genitals of female.Androgen insensitivity syndrome
    Androgen insensitivity syndrome
  6. Deficiency of an enzyme that converts one hormone into another form, regular testosterone causes develeopment of tests and internal dectwork of males, lack of the stronger form caused external genitals to form female, presence of more testesterone during puberty causes growth of penis.
    Guevodoces
  7. One testes, one ovary.
    Hermaphrodite
  8. Production of egg and production of hormones estrogen and progesterone.
    Oogenesis
  9. Carries egg to uterus, egg is usually fertized here
    Fallopian tubes
  10. Egg implants in fallopian tube or outside of uterus
    Ectopic pregnancy
  11. Site of embryo implantation, smooth muscles around edges contract during delivery.
    Uterus
  12. Isolate uterus during pregnancy, vaginal cana.
    Cervix
  13. External genitalia
    Labia
  14. Produced in hypothalamus
    GnRH
  15. Triggers ovulation, and activates structure called the corpus luteum
    LH
  16. Causes follical (egg) to mature
    FSH
  17. Releases estrogen and progesterone
    Ovaries
  18. Helps egg mature, and thickens endometrium of uterus in preparation for implantation.
    Estrogen
  19. Fursther prepares uterus for implantation of embryo.
    Progesterone
  20. Sequence of events that lead to ovulation, regulated by LH and FSH
    Ovarian cycle
  21. Known as mensrual cycle, 28 days long, and regulated by estrogen and proesterone.
    Uterine cycle
  22. Produced by embryo to maintain progesterone levels and prevents mentruation, also can be detected in pregnancy tests.
    HCG
  23. Nutrient exchange between mom and child, large surface area for exchange.
    Plcenta
  24. Stimulation of receptors in the glans penis and signals from the brain to induce a reflex reaction resulting in erection.
    Excitement
  25. Intense arousal and increased breathing, heart rate, blood pressure, and muscle tension.
    Plateau
  26. Sympathetic nerve impulses cause contraction of smooth muscles in the epididymis, glands moving semen into the urthera.
    Emission
  27. Skeletal muscle at the base of the penis contracts rhymically to force semen 2-5 ml through urethra in several spurts
    Expulsion
  28. Body returns to normal
    Resolution
  29. Can be sexual or asexual, always involves copying of genetic material, always involves the division of cells.
    Reproduction
  30. Most important structures in the reproductive system (ovaries or testes) and its function is to produce the gametes (eggs and sperm) and sex hormones.
    Gonads.
  31. Site of sperm production in testes.
    Seminiferous tubules
  32. Site where sperm are stored and mature
    Epididymis
  33. Tubes carries sperm to prostate gland
    Vas Deferens
  34. Neutralizes acids and improves sperm production
    Prostate gland
  35. Designed to pick up or respond to a variety of stimuli (Pressure, chemical, light)
    Sensory System
  36. Touch, pressure, hearing
    Mechanoreceptors
  37. Change in temperature
    Thermoreceptors
  38. Pain felt at a site other than the area of origin
    Referred pain
  39. Cannot discriminate between colors, black and white vision, poor resolution, allows us to see in dimly lit room.
