UNIT 10: Reproductive System Clicker Review

This comprehensive review covers essential topics in male and female reproductive systems, including hormone production, gametogenesis, and reproductive cycles. Key discussions include where key hormones are produced and the effects of interventions like vasectomy on semen composition. It also explores the roles of different reproductive structures, such as the Leydig cells, prostate gland, follicles, and endometrial lining. Furthermore, the review highlights the phases of the ovarian cycle and the significance of fertilization sites, as well as common STDs and their symptoms.

  1. UNIT 10: Reproductive SystemClicker Review

  2. Where is the predominant male androgen produced? • Leydig cells • Seminiferous tubules • Epididymis • Hypothalamus • Pituitary gland

  3. Where does meiosis occur in a male? • Leydig cells • Seminiferous tubules • Epididymis • Hypothalamus • Pituitary gland

  4. Which of the following is a primary sexual characteristic? • Muscle development • Hair on the body • Deeper voice • Sperm production

  5. How long do sperm cells spend in the epidydimis? • 1 day • 10 days • 20 days • 40-65 days • 65 days

  6. Where is 60% of semen volume produced? • Epididymis • Prostate gland • Seminal vesicle • Bulbourethral gland (Cowper’s gland) • Seminiferous tubule

  7. What is the function of the fluid secreted by the prostate gland? • Neutralize urine in the urethra • Neutralize the acidic environment of the vagina • Provide nutrients for sperm • All of the above

  8. If a man receives a vasectomy, what anatomical structure is cut? • Ejaculatory duct • Seminiferous tubules • Epididymis • Vas Deferens

  9. After a vasectomy, semen will contain all of the following EXCEPT: • fructose • sperm • Alkaline fluid • prostaglandins

  10. What hormone directly stimulates testosterone production? • GnRH • HCG • LH • FSH • Androgen

  11. Eggs develop in what specific structure? • follicle • oviduct • uterus • ovary • Endometrial lining

  12. What hormone directly stimulates development of the follicle in females & sperm in males? • GnRH • FSH • LH • Estrogen • Progesterone

  13. As the follicle develops, what hormone does it produce? • GnRH • FSH • LH • Estrogen • Progesterone

  14. What does the follicle develop into after ovulation? • egg • Endometrial lining • Corpus luteum • Progesterone

  15. Increasing amounts of estrogen lead to … • A bigger follicle • More FSH • More progesterone • Increase in endometrial lining

  16. A spike in which hormone causes ovulation? • GnRH • FSH • LH • Estrogen • Progesterone

  17. What hormone(s) does the corpus luteum produce? • GnRH • FSH • LH • Estrogen • Progesterone • D & E

  18. Why would the corpus luteum disintegrate? • Egg not fertilized • No HCG • Increase in FSH • Both A and B • A, B, and C

  19. What does oxytocin do? • Cause the uterus to contract • Cause milk to be release from mammary glands • Trigger ovulation • Cause milk production • Cause menopause • A and B

  20. Where does fertilization normally occur? • ovary • Oviduct/fallopian tube • uterus • cervix • Vagina

  21. Which method of birth control is the MOST effective (besides abstinence)? • Condom • Pill • Diaphragm • Foam • “Withdrawl” (coitus interuptus)

  22. Which of the following phases is NOT part of the OVARIAN cycle? • Follicular phase • Ovulatory phase • Secretory phase • Luteal phase

  23. The follicular phase of the ovarian cycle begins at the same time as the _____ phase of the menstrual cycle. • Menstrual flow • Secretory • Proliferative

  24. What does the endometrial lining look like in the secretory phase? • There isn’t any • Just starting to develop • Beginning to be vascularized • Vascularized & making glycogen

  25. How does an IUD prevent pregnancy? • Prevents maturation of follicle • Prevents release of egg • Blocks sperm from reaching egg • Harms sperm and prevents implantation

  26. During which trimester do a baby’s organs develop? • 1st (0-12 weeks) • 2nd (13-24 weeks) • 3rd (25-40 weeks)

  27. What is another name for the “birth canal”? • vagina • cervix • uterus • oviduct/fallopian tube

  28. Which STD causes the following symptoms: symptoms appear 2-21 (usually 2-10) days after sex; thick yellow, gray, or greenish discharge or drip; burning or pain during urination; swollen or tender testicles; abnormal periods or bleeding between periods • Gonorrhea • Syphilis • Genital warts (HPV) • Herpes • Hepatitis B • Chlamydia

  29. Which STD causes the following symptoms: symptoms take 1-12 weeks to appear; in the 1st stage of infection, painless sore(s) on mouth or sex organs which last 1-5 weeks; in the 2nd stage a rash develops somewhere on the body along with flu-like symptoms • Gonorrhea • Syphilis • Genital warts (HPV) • Herpes • Hepatitis B • Chlamydia

  30. Which STD causes the following symptoms: symptoms can take 1-9 months to appear; if have symptoms they include flu-like feelings that don’t go away, tiredness, jaundice, dark urine/light-colored bowel movements • HIV • Syphilis • Genital warts (HPV) • Herpes • Hepatitis B • Chlamydia

  31. Which STD causes the following symptoms: symptoms appear 1-30 days after contact; flu-like feelings; small painful blisters on the sex organs or mouth; itching or burning before the blisters appear; blisters last 1-3 weeks and then go away (you still have this condition though) • Syphilis • Genital warts (HPV) • Herpes • Hepatitis B • HIV • Chlamydia

  32. Which STD causes the following symptoms: symptoms show up 1-8 months after contact; caused by a virus; small bumps on the sex organs or anus; itching or burning around the sex organs; bumps may go away but they can come back because you still have the virus • Gonorrhea • Syphilis • Genital warts (HPV) • Herpes • HIV • Chlamydia

  33. How many functional end products result from FEMALE meiosis? • 0 • 1 • 2 • 3 • 4
