1. Which contraceptive option suppresses sperm motility and inhibits the implantation of the blastocyst?

• A. Copper-T
• B. Diaphragm
• C. Contraceptive pills
• D. Condom

Correct answer: A

Rationale: The correct answer is A, Copper-T. Copper-T is an intrauterine device that releases copper ions, which suppress sperm motility and inhibit the implantation of the blastocyst. This method mainly works by preventing fertilization and, if fertilization occurs, by making the endometrium less receptive to implantation. Choices B, C, and D are incorrect. The diaphragm is a barrier method that prevents sperm from reaching the cervix; contraceptive pills mainly work by suppressing ovulation and altering cervical mucus to prevent sperm from reaching the egg; condoms are barrier methods that prevent sperm from entering the vagina.

2. Where does fertilization normally occur?

• A. Ampulla
• B. Interstitial portion
• C. Isthmus
• D. Infundibulum

Correct answer: A

Rationale: Fertilization typically occurs in the ampulla of the fallopian tube. The ampulla provides the ideal environment for fertilization due to the presence of cilia that help transport the egg and sperm, as well as the nourishing fluid within this region. The interstitial portion, isthmus, and infundibulum of the fallopian tube are not the primary sites for fertilization. The interstitial portion connects the fallopian tube to the uterine cavity, the isthmus is the narrowest part near the uterus, and the infundibulum is the funnel-shaped end near the ovary, where the egg is captured after ovulation.

3. How many arteries are there in an umbilical cord?

• A. Three
• B. One
• C. Two
• D. Four

Correct answer: C

Rationale: There are two arteries in an umbilical cord. The umbilical cord contains two arteries and one vein. Artery carries blood away from the fetus, while the vein returns blood to the fetus. Therefore, choices A, B, and D are incorrect as they do not represent the correct number of arteries in an umbilical cord.

4. Which hormone regulates the production of milk after childbirth?

• A. Prolactin
• B. Oxytocin
• C. Estrogen
• D. Progesterone

Correct answer: A

Rationale: The correct answer is Prolactin. Prolactin is the hormone responsible for regulating the production of milk after childbirth. It stimulates the mammary glands in the breasts to produce milk. Oxytocin, on the other hand, is responsible for the ejection of milk from the breasts. Estrogen and progesterone play roles in the menstrual cycle and pregnancy but are not directly involved in milk production. Therefore, choices B, C, and D are incorrect.

5. What is another name for the breast?

• A. Sebaceous glands
• B. Racemose glands
• C. Mammary glands
• D. Axillary glands

Correct answer: C

Rationale: The correct answer is C: Mammary glands. The mammary glands are the specific glands in the breast responsible for producing milk. Sebaceous glands (choice A) are oil-producing glands in the skin, racemose glands (choice B) are not a recognized term, and axillary glands (choice D) refer to glands found in the armpit region, not the breast.
