Nokea
This connects the ovary to the uterus.
- A. Vagina
- B. Cervix
- C. Fallopian tube
- D. perineorrhaphy
Correct Answer: B
Rationale: The correct answer is B: Cervix. The cervix is the narrow passage that connects the uterus to the vagina. It acts as a barrier between the uterus and the outside environment. The other choices are incorrect because: A: Vagina is the birth canal and does not directly connect the ovary to the uterus. C: Fallopian tube connects the ovary to the uterus but does not directly attach to it. D: Perineorrhaphy is a surgical procedure to repair the perineum and is not related to connecting the ovary to the uterus.

Which hormone thickens the lining of the uterus?
- A. FSH
- B. estrogen
- C. LH
- D. progesterone
Correct Answer: B
Rationale: The correct answer is B: estrogen. Estrogen is responsible for thickening the lining of the uterus during the menstrual cycle in preparation for implantation of a fertilized egg. Follicle-stimulating hormone (FSH) stimulates the growth of ovarian follicles. Luteinizing hormone (LH) triggers ovulation. Progesterone helps maintain the uterine lining during the second half of the menstrual cycle. Estrogen plays a key role in the initial thickening of the uterine lining, making it the correct choice.
About the Fallopian tubes we can state the following:
- A. are funnel-shaped, with edges flared towards the uterus;
- B. the medial extremity displays flares;
- C. it is linked to the uterus through the uterine ostium;
- D. the lateral extremity opens in the abdominal cavity;
Correct Answer: A
Rationale: The correct answer is A because Fallopian tubes are indeed funnel-shaped, with edges flared towards the uterus. This shape helps capture the released egg from the ovary and guide it towards the uterus for potential fertilization. The other choices are incorrect because the medial extremity does not display flares (B), the Fallopian tube is not directly linked to the uterus through the uterine ostium (C), and the lateral extremity does not open in the abdominal cavity (D). Therefore, choice A is the most accurate description of the Fallopian tubes based on their anatomy and function.
Which is a sign of benign prostatic hyperplasia?
- A. Weight loss
- B. Bone pain
- C. Fever
- D. Nocturia
Correct Answer: D
Rationale: The correct answer is D: Nocturia. Benign prostatic hyperplasia (BPH) is a non-cancerous enlargement of the prostate gland, leading to urinary symptoms like frequent urination, especially at night (nocturia). Weight loss, bone pain, and fever are not typical signs of BPH. Nocturia is a common symptom due to the prostate gland pressing against the urethra, causing urinary retention. It is important to differentiate BPH symptoms from other potential causes to provide appropriate treatment.
The _____ is the space between the labia minor.
- A. vulva
- B. vestibule
- C. vaginal orifice
- D. pudendal cleft
Correct Answer: B
Rationale: The correct answer is B: vestibule. The vestibule is the space between the labia minora, housing the openings of the urethra and vagina. It is a specific anatomical term that describes this precise area. The other choices, A: vulva refers to the external female genitalia as a whole, C: vaginal orifice specifically denotes the opening of the vagina, and D: pudendal cleft is a term not commonly used in anatomy to describe this specific space. Therefore, B is the correct answer as it accurately describes the anatomical structure in question.
The spermatozoon contains:
- A. 11 pairs of somatic chromosomes;
- B. one sexual chromosome;
- C. the X sex chromosome;
- D. the Y sex chromosome;
Correct Answer: D
Rationale: The correct answer is D because the spermatozoon contains the Y sex chromosome, determining male characteristics. Sperm cells are haploid and carry only one set of chromosomes, including either an X or Y sex chromosome. The presence of the Y chromosome leads to the development of male offspring. Choice A is incorrect as sperm cells do not contain somatic chromosomes. Choice B is incorrect as sperm cells contain one pair of sex chromosomes, not just one. Choice C is incorrect because sperm cells can carry either the X or Y sex chromosome, not specifically the X chromosome.
