The fingerlike ends of fallopian tubes are called as:

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: 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.

Correct Answer: B

Rationale: The correct answer is B: 22. There are a total of 22 facial bones in the human skull. These bones include the mandible, maxilla, zygomatic bone, nasal bone, and others. Understanding human anatomy is crucial for healthcare professionals. Choice A (14) is too low and does not accurately represent the number of facial bones. Choice C (50) is too high and exceeds the actual count of facial bones. Choice D (16) is also incorrect as it falls short of the correct count of 22. Knowing the exact number of facial bones is important for various medical fields such as surgery, dentistry, and radiology.

Correct Answer: D

Rationale: Rhabdomyosarcoma is a malignant tumor arising from striated muscle cells, hence the correct answer is D. Striated muscle cells are also known as skeletal muscle cells, which are voluntary muscles responsible for movement. Smooth muscle (Choice A) and visceral muscle (Choice C) are types of involuntary muscles found in internal organs, while cardiac muscle (Choice B) is the muscle specific to the heart. Therefore, choices A, B, and C are incorrect for this question.
