The fingerlike ends of fallopian tubes are called as:
- A. Cilia
- B. Papillae
- C. Flagellae
- D. Fimbriae
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.

Rhabdomyosarcoma is the malignant tumor of the
- A. Smooth muscle
- B. Cardiac
- C. Visceral muscle
- D. Striated muscle
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.
Which of the following factors increase the risk of prostate cancer?
- A. A low-fat diet

Delayed breathing at birth is a common danger faced by newborn infants. What is a frequent cause of delayed breathing?
- A. Fetal hypoxia during the birth process
- B. Maternal hypoxia during the birth process
- C. Fetal hypercapnia
- D. Maternal hypercapnia
Correct Answer: A
Rationale: The correct answer is A: Fetal hypoxia during the birth process. Fetal hypoxia, which is a lack of oxygen to the fetus during birth, can lead to delayed breathing in newborn infants. This lack of oxygen can result from various factors such as umbilical cord compression or placental insufficiency. Maternal hypoxia (choice B) and hypercapnia (choices C and D) may affect the fetus indirectly but are not direct causes of delayed breathing in newborns. Therefore, the correct choice is A, as it directly addresses the specific cause of delayed breathing in newborn infants.
There are ____________ facial bones
- A. 14
- B. 22
- C. 50
- D. 16
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.
The corpus luteum secretes whereas oogenesis will produce ___
- A. FSH. ova/ ovum.
- B. LH.
- C. 2; 2
- D. prolactin.
Correct Answer: A
Rationale: The correct answer is A because the corpus luteum secretes progesterone, not FSH. Oogenesis produces ova/ovum, not FSH, LH, or prolactin. FSH and LH are hormones produced by the pituitary gland to regulate the menstrual cycle, not by the corpus luteum or involved in ova production. Prolactin is a hormone involved in milk production, not in oogenesis or corpus luteum function. Therefore, A is correct as it correctly identifies the function of the corpus luteum and the product of oogenesis.
