Watch this series of videos (http://openstaxcollege.org/l/oocyte) to look at the movement of the oocyte through the ovary. The cilia in the uterine tube promote movement of the oocyte. What would likely occur if the cilia were paralyzed at the time of ovulation?
Figure 43.17 Which of the following statements about the menstrual cycle is false? Progesterone levels rise during the luteal phase of the ovarian cycle and the secretory phase of the uterine cycle. Menstruation occurs just after LH and FSH levels peak. Menstruation occurs after progesterone levels drop. Estrogen levels rise before ovulation, while progesterone levels rise after.
Figure 18.12 Which of the following statements about the male reproductive system is false? a. The vas deferens carries sperm from the testes to the seminal vesicles. b. The ejaculatory duct joins the urethra. c. Both the prostate and the bulbourethral glands produce components of the semen. d. The prostate gland is located in the testes.

Rat Testis sample -Basement membrane / basal lamina (same thing) -Sertoli celland nucleus -Spermatogonia -Spermatocytes (primary or secondary) - Spermatids - Spermatozoa (nuclei and tails) - Blood vessel - Seminiferous tubule - Tubule lumen If the structures listed above are present on your photos, you must label them (if they’re not present, no need to).
Which of the following is NOT true regarding spermatogenesis? Initial spermatozoa formed are not mobile and cannot fertilize. Spematogonia have diplold chromosome. Spematocyte undergoes two rounds of division to produce 4 diploid sperm Some of the spermatogonia become reservoir cells Spematogonia breaks away from the basement membrane to develop Into sperm.
TRUE OF FALSE Primary spermatocytes are diploid in number like spermatogonia while spermatocytes are haploid in number. Spermatogenesis is the final stage of reproductive cell division by which there is the development of haploid spermatids into sperm. Spermiation is the event by which sperm are released from their connections to Sertoli cells. Digestive secretions from the small intestine complete the digestion of carbohydrates, proteins, and lipids. Bacteria in the large intestines produce minerals and nucleic acids.
