Human Reproduction and Feline Estrus Cycle of Cats! Trivia Quiz

1. If ovulation is not induced, the queen can either go into a _______ day ______ or a seasonal anestrus.

2-14, interestrus

2-14, pre-estrus

2-14, proestrus

2-14, hunger strike

If ovulation is not induced, the queen can either go into a 2-14 day interestrus. This means that she is not in a state of sexual receptivity and is not ready for mating. It is a period of sexual inactivity between estrus cycles. During this time, the queen's reproductive system is not actively preparing for mating or pregnancy.

Explanation

It is a period of sexual inactivity between estrus cycles. During this time, the queen's reproductive system is not actively preparing for mating or pregnancy.

2. Between ejaculations, sperm is primarily stored in the __________.

Epididymis

Rete testis

Seminal vesicles

Vas deferens

The correct answer is epididymis. The epididymis is a coiled tube located behind each testicle where sperm is stored and matures. It acts as a storage and maturation site for sperm, allowing them to gain the ability to swim and fertilize an egg.

Explanation

The correct answer is epididymis. The epididymis is a coiled tube located behind each testicle where sperm is stored and matures. It acts as a storage and maturation site for sperm, allowing them to gain the ability to swim and fertilize an egg.

3. Estradiol will act to __________ spinnbarkeit and progesterone will act to __________ cervical mucous ferning.

Decrease - decrease

Decrease - increase

Increase - decrease

Increase - increase

Estradiol is a form of estrogen that is responsible for promoting the growth and development of the endometrium and cervical glands. It increases the production of cervical mucus, making it more stretchable and conducive for sperm transport, which is known as spinnbarkeit. On the other hand, progesterone, which is produced after ovulation, acts to decrease the production of cervical mucus and prevents the formation of ferning patterns in the mucus. Therefore, the correct answer is "increase - decrease" as estradiol increases spinnbarkeit while progesterone decreases cervical mucous ferning.

4. Follicle stimulating hormone (FSH) is primarily responsible for __________.

Conversion of cholesterol to pregnenolone

Testosterone production

Spermatogenesis

Maintaining the corpus luteum

FSH is primarily responsible for spermatogenesis, which is the process of sperm cell development. It stimulates the Sertoli cells in the testes to support the maturation of sperm cells and promotes their growth and division. FSH also plays a role in the production of inhibin, a hormone that helps regulate the levels of FSH in the body. This process is essential for male reproductive function and the production of viable sperm cells.

5. Testosterone acts to __________ production of high density lipoproteins and estradiol acts to __________ bone resorption.

Decrease - decrease

Decrease - increase

Increase - decrease

Increase - increase

Testosterone is known to decrease the production of high density lipoproteins (HDL), which are considered "good" cholesterol. On the other hand, estradiol, a form of estrogen, acts to decrease bone resorption, which is the process of breaking down bone tissue. Therefore, the correct answer is "decrease - decrease" as both hormones have a similar effect of decreasing their respective processes.
