Reproductive System Questions and Answers
- 1.
All of the following have a haploid number of chromosomes except...
- A.
Secondary spermatocyte
- B.
Primary spermatocyte
- C.
Spermatids
- D.
Spermatozoa
Correct Answer
B. Primary spermatocyteExplanation
Primary spermatocytes have a diploid number of chromosomes, meaning they have two sets of chromosomes. This is because primary spermatocytes are formed from spermatogonia through a process called spermatogenesis, which involves DNA replication. During spermatogenesis, the number of chromosomes is reduced from diploid to haploid through two rounds of cell division, resulting in the formation of secondary spermatocytes, spermatids, and eventually spermatozoa, all of which have a haploid number of chromosomes. Therefore, the correct answer is primary spermatocyte.Rate this question:

Where does spermatogenesis occur?
- A.
Os penis
- B.
Ductus deferens of testes
- C.
Epididimis of testes
- D.
Seminiferous tubules of the testes
Correct Answer
D. Seminiferous tubules of the testesExplanation
Spermatogenesis, the process of sperm production, occurs in the seminiferous tubules of the testes. These tubules are located within the testes and are responsible for producing and maturing sperm cells. The seminiferous tubules are lined with specialized cells called Sertoli cells, which support and nourish the developing sperm cells. This is where the various stages of sperm development, including mitosis, meiosis, and spermiogenesis, take place. The other options listed, such as the os penis, ductus deferens, and epididymis, are not involved in spermatogenesis.Rate this question:
-
- 4.
The main function of the Epididymis is
- A.
Ejaculation of sperm
- B.
Storage and maturation of sperm
- C.
Thermoregulation of sperm
- D.
Deliver spermatozoa to female reproductive system
Correct Answer
B. Storage and maturation of spermExplanation
The correct answer is "storage and maturation of sperm." The epididymis is a coiled tube located on the back of each testicle. Its main function is to store sperm and allow them to mature. Sperm are produced in the testes and then transported to the epididymis where they are stored for several weeks. During this time, the sperm undergo maturation processes that enable them to become motile and capable of fertilizing an egg. When ejaculation occurs, the sperm are pushed from the epididymis into the vas deferens, which then carries them to the urethra for ejaculation.Rate this question:

What layers of the testes form the vaginal tunic?
- A.
Parietal layer and internal spermatic fascia
- B.
External and internal spermatic fascia
- C.
Skin and dartos muscle
- D.
Parietal and visceral layers
Correct Answer
D. Parietal and visceral layersExplanation
The testes are surrounded by a protective covering called the vaginal tunic. The vaginal tunic is composed of two layers: the parietal layer and the visceral layer. The parietal layer is the outer layer and the visceral layer is the inner layer. These layers provide support and protection to the testes. The other options mentioned, such as the external and internal spermatic fascia, the skin and dartos muscle, do not form the vaginal tunic.Rate this question:

The cremaster muscle is an extension of the
- A.
Transversus abdominis
- B.
Internal abdominal oblique
- C.
External abdominal oblique
- D.
Rectus abdominis
Correct Answer
B. Internal abdominal obliqueExplanation
The correct answer is internal abdominal oblique. The cremaster muscle is a thin muscle that is responsible for raising and lowering the testes in males. It is derived from the internal abdominal oblique muscle, which is one of the muscles of the abdominal wall. The internal abdominal oblique muscle is located deep to the external abdominal oblique muscle and plays a role in trunk rotation and lateral flexion of the spine.Rate this question:

The Gubernaculum is
- A.
A meshwork of veins that surround testicular artery
- B.
A band of connective tissue that attaches the testes to the scrotum
- C.
Endocrine cells between the seminiferous tubules
- D.
A structure that helps support developing spermatids
Correct Answer
B. A band of connective tissue that attaches the testes to the scrotumExplanation
The Gubernaculum is a band of connective tissue that attaches the testes to the scrotum. This structure plays a crucial role in the descent of the testes during fetal development. It guides the testes from their original position near the kidneys down into the scrotum. Once the testes have descended, the Gubernaculum becomes less prominent but still helps to anchor the testes in the scrotum. Without the Gubernaculum, the testes would not be properly positioned in the scrotum, which could lead to fertility issues or other complications.Rate this question:

The Pampiniform plexus is responsible for
- A.
Producing androgens
- B.
Spermatogenesis
- C.
Ejaculatiuon
- D.
Thermoregulation
Correct Answer
D. ThermoregulationExplanation
The Paminiform plexus is responsible for thermoregulation. This is because the paminiform plexus is a network of veins that surrounds the testicular artery in the scrotum. This network of veins helps to cool the blood that is going to the testes, which is important for maintaining the optimal temperature for spermatogenesis. By cooling the blood, the paminiform plexus helps to prevent overheating of the testes, which could be detrimental to sperm production. Therefore, thermoregulation is the correct answer.Rate this question:

What is the function of sertoli cells?
- A.
Cells that are responsible for thermoregulation
- B.
Produce androgens
- C.
Support developing spermatids
- D.
Cells that attack spermatids
Correct Answer
C. Support developing spermatidsExplanation
Sertoli cells are specialized cells found in the seminiferous tubules of the testes. Their main function is to support and nourish the developing spermatids, which are immature sperm cells. They provide physical and nutritional support to the spermatids during their maturation process, ensuring their proper development into mature sperm cells. Sertoli cells also play a role in the blood-testis barrier, which protects the developing sperm cells from harmful substances and immune attack.Rate this question:

Which end of the epididymis do the spermatozoa enter
- A.
Tail
- B.
Head
- C.
Body
Correct Answer
B. HeadExplanation
Spermatozoa enter the head of the epididymis. The epididymis is a coiled tube located on the back of each testicle, where sperm mature and gain the ability to swim. The head of the epididymis receives sperm from the testes via the efferent ductules. From the head, sperm gradually move down through the body and then into the tail of the epididymis, where they are stored until ejaculation. Therefore, the correct answer is "Head".Rate this question:
-
- 12.
Which end of the epididymis continues on as the ductus deferens
- A.
Tail
- B.
Head
- C.
Body
Correct Answer
A. TailExplanation
The tail of the epididymis continues on as the ductus deferens. The epididymis is a coiled tube located at the back of each testicle and is responsible for storing and maturing sperm. The tail of the epididymis is the final segment before the ductus deferens, which is a muscular tube that transports sperm from the epididymis to the urethra during ejaculation. Therefore, the tail of the epididymis is the correct answer as it directly connects to the ductus deferens.Rate this question:

Ejaculation is a
- A.
Sympathetic reflex
- B.
Parasympathetic reflex
Correct Answer
A. Sympathetic reflexExplanation
Ejaculation is a sympathetic reflex because it is controlled by the sympathetic nervous system. This system is responsible for the "fight or flight" response in the body, which includes the release of adrenaline and activation of various physiological processes. During ejaculation, the sympathetic nervous system stimulates the contraction of muscles in the reproductive organs, allowing for the expulsion of semen. This reflex is involuntary and occurs in response to sexual stimulation.Rate this question:

The most common site for fertilization is
- A.
Uterus
- B.
Uterine horn
- C.
Oviduct
- D.
Cervix
Correct Answer
C. OviductExplanation
The oviduct, also known as fallopian tubes, are the most common site for fertilization to occur in the female reproductive system. After ovulation, the egg is released from the ovary and travels through the oviducts. If sperm is present in the oviducts at the same time, fertilization can occur. The oviducts provide the ideal environment for the sperm to meet the egg and for fertilization to take place before the fertilized egg continues its journey to the uterus for implantation.Rate this question:

Which hormone is necessary to maintain pregnancy?
- A.
FSH
- B.
Progesterone
- C.
LH
- D.
Aldosterone
Correct Answer
B. ProgesteroneExplanation
Progesterone is necessary to maintain pregnancy because it helps prepare the uterus for implantation of a fertilized egg and supports the development of the placenta. It also helps to prevent contractions of the uterine muscles, which could potentially lead to miscarriage. Additionally, progesterone plays a role in suppressing the immune system to prevent rejection of the embryo. Overall, progesterone is essential for maintaining the proper conditions for a healthy pregnancy.Rate this question:

During which stage in the estrous cycle are females receptive to mating?
- A.
Estrus
- B.
Proestrus
- C.
Diestrus
- D.
Metestrus
Correct Answer
A. EstrusExplanation
During the estrus stage of the estrous cycle, females are receptive to mating. This is the period when the female is ovulating and is most fertile. The hormonal changes during estrus cause behavioral and physical changes that signal to potential mates that the female is ready to reproduce. These changes may include increased vocalizations, restlessness, and a swollen or reddened vulva. Mating during estrus increases the chances of successful fertilization and reproduction.Rate this question:

During which stage in the estrous cycle does the corpus luteum develop?
- A.
Estrus
- B.
Proestrus
- C.
Diestrus
- D.
Metestrus
Correct Answer
D. MetestrusExplanation
The corpus luteum develops during the metestrus stage of the estrous cycle. This stage occurs after the ovulation and is characterized by the formation of the corpus luteum from the ruptured ovarian follicle. The corpus luteum secretes progesterone, which is important for maintaining pregnancy in case fertilization occurs. If fertilization does not occur, the corpus luteum regresses, leading to the start of a new estrous cycle.Rate this question:

During which stage in the estrous cycle do females experience blood-tinged discharge and vulvar swelling?
- A.
Estrus
- B.
Proestrus
- C.
Diestrus
- D.
Metestrus
Correct Answer
B. ProestrusExplanation
During the proestrus stage of the estrous cycle, females experience blood tinged discharge and vulvar swelling. This is because proestrus is the stage right before estrus, when the female is preparing for ovulation and mating. The blood tinged discharge is caused by the increased blood flow to the reproductive organs, and the vulvar swelling is a result of the hormonal changes that occur during this stage.Rate this question:

Which of the following is not a stage in the estrous cycle?
- A.
Anestrus
- B.
Proestrus
- C.
Diestrus
- D.
Metestrus
Correct Answer
A. AnestrusExplanation
Anestrus is not a stage in the estrous cycle. The estrous cycle consists of four stages: proestrus, estrus, diestrus, and metestrus. Proestrus is the stage in which the female prepares for mating, estrus is the stage of sexual receptivity, diestrus is the stage following mating where pregnancy may occur, and metestrus is the stage between diestrus and proestrus. Anestrus refers to a period of temporary ovarian inactivity or quiescence, where there is no sexual activity or reproductive behavior.Rate this question:

A "free martin" is
- A.
The male twin with a highly functional reproductive system
- B.
The male twin with a non-functional reproductive system
- C.
The female twin with a non-functional reproductive system
- D.
The female twin with a highly-functional reproductive system
Correct Answer
C. The female twin with a non-functional reproductive systemExplanation
A "free martin" refers to a female twin with a non-functional reproductive system. In some cases, when a female calf is born with a male twin, their reproductive systems can become fused during development, resulting in infertility. This condition, known as freemartinism, occurs due to the exchange of hormones and blood between the male and female fetuses. As a result, the female twin's reproductive organs do not fully develop, making her unable to reproduce.Rate this question:
