1. Label the diagram below. J A. Ovary
I
F. Urethra opening
B. Uterus
G. Testes
C. Fallopian Tubes
H. Epididymis
D. Vagina
I.
Prostate
E. Vas deferens
J.

2. List the male parts, in order, for which sperm and semen are produced and released. TestesÆEpididymisÆVas deferensÆProstateÆUrethra opening 3. List the female parts, in order, for which an egg/ovum is created and released. OvaryÆFallopian TubeÆUterusÆCervixÆVagina 4. A. What two hormones trigger sexual maturity? LH& FSH B. What is another term for sexual maturity? Puberty C. When would a boy reach sexual maturity? When sperm is produced D. When would a girl reach sexual maturity? When an egg is produced, or menstruation has occurred 5. When sperm fertilizes an egg, what is the result? zygote 6. In males, what 2 things does the hormone testosterone influence (or do)? Male sexual characteristics make sperm
7. In females, what 3 things does the hormone estrogen do? Prepare uterus for pregnancy make eggs female sexual characteristics 8. True / False (circle one): Brother and sister can be identical twins. Identical twins are created when one zygote (that was created by the fertilization of one egg and one sperm) spontaneously splits into two cells. This means that their DNA is exactly the same, which also means their gender has to be the same as well. 9. Compare and contrast: Identical vs. Fraternal twins Different genes Same age Same genes (same gender) One egg/one sperm Two eggs/two sperm Grows in uterus Two placentas Covered by One placenta amnion/surrounded by fluid 10. Explain what is happening in the diagram below. Also, label each with the correct process. Explanation: Meiosis that produces gametes (sex cells). Gametes are haploid. Males make 4 mature sperm cells each time Females make 1 mature egg, once a month
Spermatogenesis Oogenesis 11. Label the parts of the sperm cell below Head Nucleus Mid piece/ mitochondrion
Tail/flagellum
A. Which part contains digestive enzymes which allow it to get through the egg’s membrane? Acrosome (in head) B. Which part allows the sperm to be mobile, helping it to reach the egg? Flagellum
12. Label the 3 phases of the menstrual cycle on the diagram below.
Luteal phase Flow phase
Follicular phase
Days 1 ‐ 5/6 = Flow phase. Days 5/6 – 14/15 = Follicular phase. Days 14/15 ‐ 28 ish = Luteal phase. 13. Describe the role of the corpus luteum. It supplies hormones to developing zygote and helps prepare endometrium for blastocyst to implant 14. Put the following terms in order, according to fetal development: fetus, blastocyst, embryo, gastrula, zygote zygoteÆblastocystÆgastrulaÆ embryoÆfetus For the next 9 questions, use the numbers 1, 2, or 3 to label the description as taking place in either the first, second, or third trimester of fetal development (respectively). 15. ____1____ Heart begins to beat. 16. ____1____ Embryo is considered a fetus.
20. ___3_____ Fetus turns upside down (head down).
17. ___3_____ Lungs are fully developed.
21. ___2_____ Fetus has more regular sleep cycles.
18. ___2_____ Fetus breathes amniotic fluid to
22. ___1____ Sex organs can show gender of fetus.
help develop lungs. 19. ___3_____ Bones harden.
23. ____2____ Fine body hair a waxy substance help protect the fetus’s skin.
24. How are the following terms related: placenta, umbilical cord, amniotic sac.They all work to cushion, protect, and nourish the embryo. The umbilical cord connects the fetus to placenta and the placenta connects the fetus to the mother. These 2 structures help nourish the fetus. The amniotic sac holds everything together and cushions/supports the fetus. 25. Which structure in development is composed of embryonic stem cells? Blastocyst
26. At which stage in development would determination occur? (between which 2 structures) Blastocysts & gastrula 27. Fill in the chart for the STDs below STD
