1. Which hormone is released from the testes?

• A. Progesterone
• B. Vasopressin
• C. Testosterone
• D. None of the above

Correct answer: C

Rationale: The correct answer is testosterone. Testosterone is the primary male sex hormone produced in the testes. Progesterone is a female sex hormone primarily produced in the ovaries, not in the testes. Vasopressin is a hormone released by the pituitary gland to regulate water balance in the body, not produced by the testes. Therefore, choices A, B, and D are incorrect.

2. What is the triangular space lying between the vaginal and rectal canals?

• A. Pelvic floor
• B. Perineum
• C. Vestibule
• D. Perineal body

Correct answer: B

Rationale: The correct answer is B: Perineum. The perineum is the triangular space located between the vaginal and rectal canals. It is a region containing various muscles, nerves, and blood vessels that support the pelvic floor. Choice A, Pelvic floor, refers to the structure supporting the organs in the pelvic cavity, not the space between the vaginal and rectal canals. Choice C, Vestibule, is the space within the labia minora containing the openings of the urethra and vagina, not the area between the vaginal and rectal canals. Choice D, Perineal body, is a fibromuscular mass in the perineum area but not the space between the vaginal and rectal canals.

3. What is a characteristic of threatening abortion?

• A. Os open.
• B. Firm contracted uterus.
• C. Heavy bleeding.
• D. Severe cramping.

Correct answer: B

Rationale: Threatening abortion is characterized by a firm contracted uterus with an open os. This presentation indicates a risk of miscarriage. Choice A ('Os open') is not specific enough and does not fully describe the condition. Choices C ('Heavy bleeding') and D ('Severe cramping') can also be present in threatening abortion, but the primary characteristic is a firm contracted uterus with an open os.

4. The upper folds of the labia minora surround the clitoris and unite to form the:

• A. Frenulum
• B. Prepuce
• C. Fourchette
• D. Vestibule

Correct answer: B

Rationale: The correct answer is B: Prepuce. The upper folds of the labia minora surround the clitoris and unite to form the prepuce, which is a hood-like structure protecting the clitoris. The frenulum (choice A) is a small fold of tissue under the tongue or upper lip, not related to the female genitalia. The fourchette (choice C) refers to the area where the labia minora meet at the posterior end of the vulva, not involving the clitoris. The vestibule (choice D) is the space between the labia minora containing the vaginal and urethral openings, not directly formed by the upper folds of the labia minora.

5. After fertilization, cell division occurs through a process of:

• A. Binary fission
• B. Meiosis
• C. Budding
• D. Mitosis

Correct answer: D

Rationale: After fertilization, the zygote undergoes cell division through the process of mitosis. Mitosis is the type of cell division that results in two daughter cells with the same number of chromosomes as the parent cell. Choice A, binary fission, is a form of asexual reproduction in prokaryotes, not the process that occurs after fertilization in multicellular organisms. Choice B, meiosis, is a type of cell division that leads to the formation of gametes with half the number of chromosomes, not the process that occurs after fertilization. Choice C, budding, is a form of asexual reproduction seen in some organisms like yeast, but it is not the process of cell division after fertilization.
