Which one of the following is not a stage in the ovarian cycle of the menstrual cycle?

Correct Answer: A

Rationale: The correct answer is A. The recruitment of the Graafian follicle is indeed a stage in the ovarian cycle. During the ovarian cycle, the primary follicles are recruited to develop further, leading to the formation of the Graafian follicle. The selection of the dominant follicle, luteal phase, and formation of the corpus luteum are other essential stages in the ovarian cycle. Therefore, option A is not correct as it is a crucial phase in the process of ovulation and fertilization.

Correct Answer: B

Rationale: The correct answer is B because the Platypelloid pelvis indeed has an oval inlet. Gynaecoid pelvis, not mentioned in the choices, has a round inlet. Anthropoid pelvis has a long, narrow oval inlet, which makes choice C incorrect. Choice D is incorrect as the Android pelvis is actually heart-shaped with a narrowed inlet.

Correct Answer: A

Rationale: During pregnancy, the breasts undergo significant anatomical and physiological changes. These changes include increased breast tenderness, an increase in circulatory supply to the breasts, resulting in breast enlargement, and the secretion of colostrum. Choice B is incorrect as breast tenderness actually increases during pregnancy. Choice C is incorrect as the circulatory supply to the breasts increases rather than reduces. Choice D is incorrect as breasts do undergo notable changes during pregnancy.

Correct Answer: D

Rationale: The correct answer is D, All of these. Copper T, Condom, and Diaphragm are all examples of contraceptives used to prevent pregnancy. Copper T is an intrauterine device (IUD) that is placed inside the uterus to prevent pregnancy. Condoms are barrier contraceptives worn over the penis or inserted into the vagina to prevent sperm from reaching the egg. Diaphragms are also barrier contraceptives that cover the cervix to prevent sperm from entering the uterus. Therefore, all options listed (Copper T, Condom, Diaphragm) are indeed contraceptives, making 'All of these' the correct choice.

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.
