The ovarian phase between the end of menstruation and beginning of ovulation is the

Correct Answer: C

Rationale: The correct answer is C: Proliferative phase. During this phase, the endometrium thickens in preparation for a potential implantation of a fertilized egg. This phase occurs after the menstrual phase and before ovulation, marking the time when the ovarian follicles are developing under the influence of FSH. The other choices are incorrect because the menstrual phase (A) refers to the shedding of the endometrium, the preovulatory phase (B) occurs just before ovulation, and the follicular phase (D) includes both the menstrual and preovulatory phases.

Correct Answer: D

Rationale: The correct answer is D: Fimbriae. Fimbriae are the fingerlike projections at the end of the fallopian tubes that help capture the released egg from the ovary. They create a sweeping motion to guide the egg into the tube for fertilization. Cilia (A) are hair-like projections that help with movement, but they are not specific to the fallopian tubes. Papillae (B) are small, raised projections found in various organs, not in the fallopian tubes. Flagellae (C) are whip-like structures used for movement in some cells, not found in the fallopian tubes. In summary, fimbriae are specifically designed to capture and guide the egg, making them the correct choice.

Correct Answer: C

Rationale: Step-by-step rationale for why choice C is correct: 1. PID stands for Pelvic Inflammatory Disease. 2. PID is an infection of the female reproductive organs, including the uterus, fallopian tubes, and ovaries. 3. Symptoms include pelvic pain, abnormal vaginal discharge, fever, and painful urination. 4. Choice A is incorrect because PID does not specifically refer to the prostate. 5. Choice B is incorrect as PID does not involve infiltration but rather inflammation. 6. Choice D is incorrect as PID is not a disorder that inhibits the prostate.

Correct Answer: C

Rationale: The correct answer is C: Foreskin. Circumcision involves the surgical removal of the foreskin, the retractable double-layered fold of skin that covers the head of the penis. This procedure is commonly practiced for cultural, religious, or medical reasons. Removing the glans penis (A) or scrotum (B) would be highly inappropriate and damaging. The vas deferens (D) is a duct that carries sperm from the testes, which is not involved in circumcision. Therefore, the correct anatomical structure that is removed during circumcision is the foreskin.

Correct Answer: A

Rationale: The correct answer is A: Frontal bone. The frontal bone forms the forehead as it comprises the upper part of the eye sockets and the frontal part of the skull. It also houses the frontal sinuses. The parietal bone (B) forms the top and sides of the skull. The temporal bone (C) forms the sides and base of the skull, housing the ear structures. The occipital bone (D) forms the back and base of the skull, containing the foramen magnum. Therefore, the frontal bone is the only choice that directly contributes to the structure of the forehead.
