A woman who has never conceived a child is called as:
- A. Primipara
- B. Nulligravida
- C. Nullipara
- D. Primigravida
Correct Answer: C
Rationale: The correct answer is C: Nullipara. Nullipara refers to a woman who has never given birth to a child. "Nulli-" means none or zero, and "-para" refers to giving birth. This term specifically indicates the absence of any childbirth experience, regardless of pregnancy history.
A: Primipara would refer to a woman who has given birth to one child.
B: Nulligravida would refer to a woman who has never been pregnant.
D: Primigravida would refer to a woman who is pregnant for the first time.
Therefore, C is the correct choice as it accurately describes a woman who has not experienced childbirth.

Which gland provides fructose, a sugar in semen that energizes sperm?
- A. Seminal vesicles
- B. Bulbourethral gland
- C. Prostate
- D. Epididymis
Correct Answer: A
Rationale: The correct answer is A: Seminal vesicles. These glands produce fructose, a sugar in semen that provides energy for sperm. Seminal vesicles are located near the base of the bladder and are responsible for producing a significant portion of the fluid in semen. The other choices are incorrect because the bulbourethral gland produces a clear lubricating fluid, the prostate produces a milky fluid that helps with sperm motility and viability, and the epididymis is a coiled tube where sperm mature and are stored, but it does not produce fructose.
______________________ is the motion that extends the foot downward toward the ground as when pointing the toes or stepping on the gas pedal.
- A. Dorsiflexion
- B. Plantar flexion
- C. Rotation
- D. Flexion
Correct Answer: B
Rationale: The correct answer is B: Plantar flexion. Plantar flexion refers to the motion of extending the foot downward towards the ground, like when pointing the toes or pressing the gas pedal. This action is mainly controlled by the calf muscles, particularly the gastrocnemius and soleus. Dorsiflexion (A) is the opposite motion, where the foot is flexed upward towards the shin. Rotation (C) involves turning around an axis and is not relevant to this specific movement. Flexion (D) refers to the bending of a joint, not the extension of the foot downward. In summary, plantar flexion is the correct answer because it accurately describes the motion of extending the foot downward, while the other choices do not match the described movement.
Which of the following is produced by the trophoblast cells during the first 3 weeks of pregnancy?
- A. Estrogen
- B. Luteinizing hormone
- C. Oxytocin
- D. Human chorionic gonadotropin
Correct Answer: D
Rationale: The correct answer is D: Human chorionic gonadotropin (hCG). During the first 3 weeks of pregnancy, trophoblast cells produce hCG, which is crucial for maintaining the corpus luteum and ensuring the production of progesterone to support the early pregnancy. hCG is also the hormone detected in pregnancy tests.
Rationale:
A: Estrogen is mainly produced by the ovaries, not trophoblast cells in the early stages of pregnancy.
B: Luteinizing hormone is produced by the pituitary gland to trigger ovulation, not by trophoblast cells.
C: Oxytocin is produced by the hypothalamus and released by the pituitary gland during labor and breastfeeding, not by trophoblast cells in the early stages of pregnancy.
Testicular cancer usually arises from the _____.
- A. scrotal sac
- B. seminiferous tubules
- C. epididymis
- D. interstitial cells
Correct Answer: B
Rationale: The correct answer is B: seminiferous tubules. Testicular cancer arises from the cells within the seminiferous tubules where sperm production occurs. These tubules are the most common site for testicular cancer to develop. The other choices are incorrect because testicular cancer typically does not originate from the scrotal sac (A), epididymis (C), or interstitial cells (D). The scrotal sac contains the testicles but does not produce cancer, the epididymis is a different structure involved in sperm maturation, and interstitial cells produce hormones rather than sperm.
Mucous membrane partially or completely covering the vaginal orifice is called as:
- A. Clitoris
- B. Labia
- C. Hymen
- D. Vulva
Correct Answer: C
Rationale: The correct answer is C: Hymen. The hymen is a mucous membrane that partially or completely covers the vaginal orifice. It is a thin tissue located at the opening of the vagina. The hymen can vary in appearance and may partially cover the vaginal opening, making it an essential anatomical structure to consider. The other choices are incorrect because:
A: Clitoris - The clitoris is a highly sensitive sexual organ located above the vaginal opening, not covering it.
B: Labia - The labia are the folds of skin surrounding the vaginal opening, not covering it entirely.
D: Vulva - The vulva refers to the external female genitalia, including the labia, clitoris, and vaginal opening, but it does not specifically refer to the mucous membrane covering the vaginal orifice.
