What is the area of the uterus where the fallopian tubes are inserted known as?
- A. Fundus
- B. Corpus or body
- C. Cavity
- D. Cornua
Correct Answer: D
Rationale: The correct answer is D, Cornua. The cornua refers to the upper, horn-like parts of the uterus where the fallopian tubes are inserted. The fundus (choice A) is the rounded top portion of the uterus, the corpus or body (choice B) is the main part of the uterus excluding the cervix and fundus, and the cavity (choice C) refers to the internal space within the uterus. Therefore, choices A, B, and C are incorrect as they do not specifically denote the area where the fallopian tubes are inserted.

The _________ is a temporary organ that connects a mammalian mother to its foetus.
- A. Placenta
- B. Chorion
- C. Endometrium
- D. None of the above
Correct Answer: A
Rationale: The correct answer is A: Placenta. The placenta is a temporary organ that connects a mammalian mother to its foetus. It plays a crucial role in facilitating the exchange of nutrients, oxygen, and waste between the mother and the developing baby. Choice B, Chorion, is incorrect as it is a part of the fetal membrane but not the organ that connects the mother to the fetus. Choice C, Endometrium, is incorrect as it is the lining of the uterus where implantation occurs but is not the organ responsible for connecting the mother to the fetus. Choice D, None of the above, is incorrect as the placenta specifically fits the description provided in the question.
Discuss the anatomical/physiological changes in pregnancy under the following: Uterus
- A. The uterus softens in the anterior midline, becomes flexible at the uterocervical junction, blood vasculature increases in size and number, and hypertrophy of myometrial cells occurs.
- B. The uterus decreases in size during pregnancy and remains rigid.
- C. The uterus size remains unchanged, and no changes occur in the blood vasculature.
- D. Uterus becomes more rigid and hypertrophies.
Correct Answer: A
Rationale: During pregnancy, the uterus undergoes various anatomical and physiological changes. The correct answer, Choice A, accurately describes these changes. The uterus softens in the anterior midline, becomes flexible at the uterocervical junction, experiences an increase in blood vasculature size and number, and myometrial cells hypertrophy. This softening and increased vascularity are essential for accommodating the growing fetus and facilitating delivery. Choices B, C, and D are incorrect because they do not reflect the typical changes that occur in the uterus during pregnancy. The uterus does not decrease in size, remain unchanged in size, become more rigid, or hypertrophy without the described softening and vascular changes.
Which of the following are examples of external genitalia?
- A. Mons veneris
- B. Labia majora
- C. Vagina
- D. Cervix
Correct Answer: A
Rationale: The correct answer is A: Mons veneris. The mons veneris and labia majora are considered external genitalia as they are visible externally. The vagina and cervix, on the other hand, are internal structures. The vagina is the canal leading from the external genitals to the cervix, which is the lower, narrow portion of the uterus.
During the menstrual cycle, which hormone maintains the corpus luteum?
- A. Luteinizing hormone
- B. Follicle-stimulating hormone
- C. Progesterone
- D. Relaxin
Correct Answer: A
Rationale: During the menstrual cycle, luteinizing hormone maintains the corpus luteum. The correct answer is A. Luteinizing hormone stimulates the corpus luteum to produce progesterone. Choice B, Follicle-stimulating hormone, is involved in stimulating the growth of follicles in the ovaries. Choice C, Progesterone, is produced by the corpus luteum and plays a role in preparing the endometrium for implantation. Choice D, Relaxin, is involved in processes such as softening the cervix and ligaments during pregnancy, but it is not responsible for maintaining the corpus luteum.
