The gonads produce sex cells, also spermatids into sperm is known as known as ________, ________.
- A. zygotes
- B. mitosis
- C. interstitial cells
- D. spermiogenesis
Correct Answer: D
Rationale: The correct answer is D: spermiogenesis. Spermiogenesis is the process where spermatids mature into sperm cells in the testes. The gonads (testes in males) produce sex cells, but zygotes are formed through fertilization, not spermiogenesis. Mitosis is a type of cell division for growth and repair, not sperm production. Interstitial cells are found in the testes but are responsible for producing testosterone, not the maturation of spermatids into sperm cells. Therefore, option D is the correct choice as it specifically relates to the transformation of spermatids into sperm cells in the testes.

In order for male differentiation to occur during embryonic development, testosterone must be secreted from the testes. What stimulates the secretion of testosterone during embryonic development?
- A. Luteinizing hormone from the maternal pituitary gland
- B. Human chorionic gonadotropin
- C. Inhibin from the corpus luteum
- D. Gonadotropin-releasing hormone from the embryo’s hypothalamus
Correct Answer: B
Rationale: The correct answer is B: Human chorionic gonadotropin (hCG) stimulates the secretion of testosterone during embryonic development. hCG is produced by the developing embryo and acts on the Leydig cells in the testes to trigger the production of testosterone. This hormone plays a crucial role in male differentiation by promoting the development of male reproductive organs.
A: Luteinizing hormone (LH) from the maternal pituitary gland is not involved in the early stages of male differentiation in the embryo. LH is typically involved in the regulation of testosterone production postnatally.
C: Inhibin from the corpus luteum is not involved in the stimulation of testosterone secretion during embryonic development. Inhibin is mainly involved in the negative feedback regulation of FSH secretion.
D: Gonadotropin-releasing hormone (GnRH) from the embryo's hypothalamus is not responsible for directly stimulating testosterone secretion during embryonic development. GnRH regulates the secretion
The process of creating female gametes is called ________.
- A. spermatogenesis
- B. oogenesis
- C. spermiogenesis
- D. cleavage
Correct Answer: B
Rationale: The correct answer is B: oogenesis. Oogenesis is the process of creating female gametes (eggs) through meiosis in the ovaries. Spermatogenesis (A) is the process of creating male gametes (sperm). Spermiogenesis (C) is the final stage of spermatogenesis where spermatids mature into sperm. Cleavage (D) refers to the rapid cell divisions that occur after fertilization. Therefore, B is the correct answer as it specifically relates to the formation of female gametes.
Which question should the nurse ask when assessing a 60-yr-old patient who has a history of benign prostatic hyperplasia (BPH)?
- A. “Have you noticed any unusual discharge from your penis?”
- B. “Has there been any change in your sex life in the past year?”
- C. “Has there been a decrease in the force of your urinary stream?”
- D. “Have you been experiencing any difficulty in achieving an erection?”
Correct Answer: C
Rationale: The correct question to ask when assessing a 60-yr-old patient with a history of BPH is C: “Has there been a decrease in the force of your urinary stream?” This question is relevant as BPH commonly causes urinary symptoms like weak urinary stream. Asking about unusual discharge (A) is more relevant for assessing sexually transmitted infections. Inquiring about changes in sex life (B) and difficulty achieving an erection (D) are more related to erectile dysfunction, which may not be directly linked to BPH in this context.
Sexual feelings are normal and necessary
- A. for reproduction to occur
- B. for the heart and lungs to function properly
- C. for an ovum to be released from a female’s ovary each month
- D. for teens to become adults
Correct Answer: A
Rationale: The correct answer is A because sexual feelings are indeed necessary for reproduction to occur. Sexual arousal and desire play a vital role in initiating the process of conception and ensuring the continuation of the human species. Without sexual feelings, procreation would not be possible.
Explanation for why the other choices are incorrect:
B: Sexual feelings are not necessary for the heart and lungs to function properly. These bodily functions are regulated by the autonomic nervous system, not by sexual arousal.
C: While sexual feelings can influence the release of an ovum during ovulation, they are not the sole factor. Ovulation can occur without sexual arousal.
D: Sexual feelings are not a requirement for teenagers to become adults. Puberty and the physical and emotional changes that come with it mark the transition from adolescence to adulthood, not sexual feelings.
Which part of the uterus opens into the vagina?
- A. Urethra
- B. Cervix
- C. Uterine tubes
- D. Inguinal canal
Correct Answer: B
Rationale: The correct answer is B: Cervix. The cervix is the lower part of the uterus that opens into the vagina. It acts as a barrier between the uterus and vagina, and allows for the passage of menstrual flow, sperm, and a baby during childbirth. The other choices are incorrect because the urethra is a tube that connects the bladder to the outside of the body, the uterine tubes are also known as fallopian tubes that connect the ovaries to the uterus, and the inguinal canal is a passage in the abdominal wall.
