Er Reproduction Part 1: Canine Estrus Cycle - Quiz

Quiz Preview

  • 2. 

    ______ is the prolonged period of sexual rest. (They sure needed it)

    • Anestrus

    • Estrus

    • Diestrus

    • Postestrus

    Correct Answer
    A. Anestrus
    Explanation
    Anestrus is the correct answer because it refers to the prolonged period of sexual rest in animals. During anestrus, animals experience a temporary cessation of reproductive activity, which can last for several months. This period allows the animals to recover and prepare for the next reproductive cycle. The phrase "They sure needed it" suggests that the animals were in need of a break from their sexual activity, further supporting the choice of Anestrus as the correct answer.

    Rate this question:

  • 3. 

    Proestrus lasts about _____ .

    • 9 days

    • 3 months

    • 3-4 weeks

    • 10 days

    Correct Answer
    A. 9 days
    Explanation
    Proestrus is the initial phase of the estrous cycle in female mammals, including dogs. During this phase, the female is not yet ready to mate and experiences physical and behavioral changes. The correct answer, 9 days, indicates the duration of the proestrus phase. This means that for approximately 9 days, the female will exhibit signs such as vaginal bleeding, swelling of the vulva, and attracting male attention, but she will not be receptive to mating.

    Rate this question:

  • 4. 

    Estrus lasts about ____.

    • 9 days

    • 10 days

    • 1 week

    • 3-5 months

    Correct Answer
    A. 9 days
    Explanation
    Estrus, also known as the "heat" cycle, is the period in the reproductive cycle of female mammals during which they are sexually receptive and fertile. In most mammals, including dogs and cats, estrus typically lasts for about 9 days. This is the time when the female is most likely to mate and conceive. It is important for pet owners to be aware of their pet's estrus cycle to prevent unwanted pregnancies and to provide appropriate care during this time.

    Rate this question:

  • 5. 

    Whelping can be accurately predicted from day 1 of estrus.

    • True

    • False

  • 6. 

    Glandular secretions increase. Vaginal epithelium becomes hyperemic. Ovulation occurs.

    • Estrus

    • Anestrus

    • Proestrus

    • Diestrus

    Correct Answer
    A. Estrus
    Explanation
    The given symptoms of glandular secretions increasing and vaginal epithelium becoming hyperemic are characteristic of the estrus phase of the estrous cycle. Estrus is the period of sexual receptivity in female mammals, during which ovulation occurs. This phase is marked by increased hormone levels and physical changes in the reproductive tract, preparing the female for potential mating and fertilization. Therefore, the correct answer is estrus.

    Rate this question:

  • 8. 

    Vulvar edema, hyperemia, serosanguineous/hemorrhagic discharge. Male not accepted. What stage of the estrous cycle is it?

    • Proeostrus

    • Diaestrus

    • Anestrus

    • Estrous

    Correct Answer
    A. Proeostrus
    Explanation
    The symptoms described, including vulvar edema, hyperemia, and serosanguineous/hemorrhagic discharge, are characteristic of the proestrus stage of the estrous cycle. Proestrus is the initial stage of the cycle, marked by the preparation of the reproductive tract for potential mating. During this stage, the vulva becomes swollen and congested, and there may be a discharge of blood-tinged fluid. This is followed by estrus, when the female is receptive to mating. Therefore, the correct answer is Proeostrus.

    Rate this question:

  • 9. 

    During ____, the corpora lutea are fully functional and secrete large quantities of ______.

    • Diestrus, progesterone

    • Diestrus, estrogen

    • Esterus, progesterone

    • Estrus, estrogen

    Correct Answer
    A. Diestrus, progesterone
    Explanation
    During diestrus, the corpora lutea are fully functional and secrete large quantities of progesterone.

    Fluffy the male dog asked Cookie the female dog to mate with him.She said GET LOST. And he was like but whyyyyy??Her response:  "I am experiencing an abrupt decline in the percentage of my cornified cells, and my neutrophils are beginning to fade away." 

    • OMG she must be in diestrus !

    • Omg she must be stupid he's such a hot dog....

    • Omg she must be in estrus, I totally understand.

    • Omg she must be in metestrus!

    Correct Answer
    A. OMG she must be in diestrus !
    Explanation
    The correct answer is "OMG she must be in diestrus!" because the female dog's response indicates that she is experiencing changes in her reproductive cycle. Diestrus is a stage in the estrous cycle of female mammals, including dogs, where the reproductive organs return to their normal state after ovulation. The decline in cornified cells and fading neutrophils are characteristic of diestrus. This suggests that the female dog is not ready to mate at the moment.

    Rate this question:

  • 11. 

    During proestrus, estradiol concentration ______ as ovarian follicles ____ and the uterus enlarges.

    • Increases, mature

    • Decreases, mature

    • Increases, release the ova

    • Decreases, release the ova

    Correct Answer
    A. Increases, mature
    Explanation
    During proestrus, the concentration of estradiol increases as ovarian follicles mature and the uterus enlarges. Estradiol is a hormone produced by the developing follicles in the ovaries. As the follicles mature, they release increasing amounts of estradiol into the bloodstream. This rise in estradiol levels triggers the growth and thickening of the uterine lining in preparation for potential pregnancy. Therefore, the correct answer is "Increases, mature."

    Rate this question:

  • 12. 

    Corpora Lutea are present during ______.

    • Diestrus

    • Metestrus

    Rate this question:

  • 13. 

    The reproductive phase that immediately precedes estrus is ______.

    • Proestrus

    • Diaestrus

    • Anestrus

    • Pro-marijuana

    Correct Answer
    A. Proestrus
    Explanation
    Proestrus is the correct answer because it is the reproductive phase that occurs immediately before estrus in female animals. During this phase, the ovaries start to develop follicles, and the hormone estrogen is released, preparing the body for ovulation and mating. This phase is characterized by changes in behavior and physical signs such as swelling of the vulva and discharge. Proestrus typically lasts for a few days to a week, depending on the species.

    Rate this question:

  • 14. 

    Vaginal smears during ______ will reveal mostly RBC, and a mixture of epithelial cells/neutrophils.

    • Proestrus

    • Diaestrus

    • Anestrus

    • Estrous

    Correct Answer
    A. Proestrus
    Explanation
    During proestrus, the stage before the female dog enters into estrus or heat, the vaginal smears will reveal mostly red blood cells (RBC) along with a mixture of epithelial cells and neutrophils. This is because during proestrus, the uterine lining is preparing for potential implantation of fertilized eggs, which leads to increased blood flow and shedding of the uterine lining. Additionally, the presence of epithelial cells and neutrophils suggests inflammation and increased immune response in the reproductive tract during this stage.

    Rate this question:

  • 15. 

    The interval between 2 successive estrus cycles is typically ______ months.

    • 7

    • 8

    • 6

    • 9

    Correct Answer
    A. 7
    Explanation
    The interval between 2 successive estrus cycles is typically 7 months. This means that female animals experience estrus, or heat, every 7 months. This is a natural reproductive cycle for many animals, allowing them to conceive and give birth at regular intervals.

    Rate this question:

  • 16. 

    During _____, vulvular swelling decreases and discharge changes to straw color or may be bloody.

    • Estrus

    • Metestrus

    • Proestrus

    • Diestrus

    Correct Answer
    A. Estrus
    Explanation
    During estrus, vulvular swelling decreases and discharge changes to straw color or may be bloody. This is because estrus is the stage of the reproductive cycle in female mammals where they are sexually receptive and ready to mate. The decrease in vulvular swelling indicates that the female is no longer in the pre-mating stage, while the change in discharge color is a result of hormonal changes in the body. This is a natural process that occurs during estrus to prepare the female for potential fertilization.

    Rate this question:

  • 17. 

    Anestrus lasts about _____.

    • 90-150 days

    • 100-150 days

    • 6 weeks

    • 3-5 months

    Correct Answer
    A. 90-150 days
    Explanation
    The correct answer is 90-150 days. Anestrus is a period of sexual inactivity in female animals, particularly in mammals. During this time, the female does not experience estrus or ovulation. The duration of anestrus can vary depending on the species and individual factors. In general, it lasts for approximately 90-150 days, which is the time when the female's reproductive system is inactive and not receptive to mating.

    Rate this question:

  • 18. 

    Estrus vaginal smears will reveal mostly ______, occasional ___, and no WBC.

    • Cornified epithelial cells, bacteria

    • Non-cornified epithelial cells, RBC

    • Cornified epithelial cells, RBC

    • Non-cornified epithelial cells, RBC

    Correct Answer
    A. Cornified epithelial cells, bacteria
    Explanation
    Estrus vaginal smears are used to examine the cells present in the vaginal secretions of a female animal during estrus (the fertile period). Cornified epithelial cells are typically seen during this phase, as they are shed from the vaginal lining. Bacteria may also be present in small amounts. Non-cornified epithelial cells and white blood cells (WBC) are not typically observed during estrus.

    Rate this question:

  • 19. 

    Diestrus lasts about ___________.

    • 50-80 days

    • 60-70 days

    • 3-4 weeks

    • 9 days

    Correct Answer
    A. 50-80 days
    Explanation
    Diestrus is a phase in the reproductive cycle of female mammals, characterized by a period of sexual inactivity. It typically lasts for a longer duration, ranging from 50 to 80 days. During this phase, the female is not receptive to mating and the reproductive organs undergo changes in preparation for the next phase of the cycle. Therefore, the correct answer is 50-80 days.
