1. Describe the various types of uteri (e.g., didelphic vs bicornuate) and give an example of a species with each.

2. Describe the two meiotic arrests in oocyte development, when they occur, and what their trigger is to resume meiosis.

3. Describe how you differentiate between primordial, primary, secondary and teriary follicles in the ovary. Identify the types of cells present at each stage.

4. Describe the OVARIAN structures present on the ovary during the estrous cycle and put them in the order in which they appear.

5. Describe all of the phases associated with the development of a follicular wave in cattle. Indicate which hormones are responsible for each phase of development. Identify hormones being produced by the follicles at the various stages.

6. Describe the process of events leading from the GnRH surge to ovulation.

7. Describe the process of the sperm binding the oocyte and the acrosome reaction.

8. Identify three functions of the uterus.

9. Compare and contrast the anatomy of the cervix in the cow and the sow.

10. Explain the 2-cell, 2-gonadotropin theory of the ovarian cells. Include locations for the cell types in the ovary.

11. Identify the site of semen deposition in the cow in natural mating and AI.

12. For each anatomical location in the female’s reproductive tract, describe how sperm numbers are reduced at each location.

13. Use the word “estrous” correctly in a sentence.

14. Describe the stages of the estrous cycle – in the order in...
