FSH causes several immature EGGS, along with their surrounding FOLLICLE cells, in the ovaries to begin to develop. The developing follicle cells release increasing amounts of ________________.
- A. hormone
- B. estrogen
- C. progesterone
- D. Implantation
Correct Answer: B
Rationale: Step-by-step rationale:
1. FSH stimulates development of follicles in ovaries.
2. Follicle cells release estrogen.
3. Estrogen levels increase as follicles develop.
4. Estrogen plays key role in menstrual cycle regulation.
Therefore, the correct answer is B (estrogen). Other choices are incorrect: A (hormones are broad, not specific), C (progesterone is released after ovulation), D (implantation occurs in the uterus, not ovaries).

Inflammation of bone and bone marrow secondary to infection is called?
- A. Osteitis.
- B. Osteochondritis.
- C. Osteom
- D. Osteomyelitis
Correct Answer: D
Rationale: The correct answer is D: Osteomyelitis. Osteomyelitis refers to inflammation of bone and bone marrow secondary to infection. "Osteitis" (choice A) is a general term for bone inflammation without specifying infection. "Osteochondritis" (choice B) is inflammation of bone and cartilage, not bone marrow. "Osteom" (choice C) is not a recognized medical term. Therefore, based on the specific definition provided in the question, osteomyelitis is the most appropriate answer.
A fertilized egg, which represents the first cell of a new individual, is called a(n) ________.
- A. blastocyst
- B. zygote
- C. fetus
- D. embryo
Correct Answer: B
Rationale: The correct answer is B: zygote. A zygote is formed when a sperm cell fertilizes an egg cell, marking the beginning of a new individual's development. It is the first cell of the new organism with a full set of chromosomes.
A: Blastocyst is a later stage of development after the zygote has undergone several cell divisions.
C: Fetus refers to the later stages of development when the embryo has developed recognizable features.
D: Embryo is the stage after the zygote when the cells start to differentiate into different tissues and organs.
During the follicular phase of the female menstrual cycle
- A. the secretion of luteinising hormone and follicle stimulating hormone are being inhibited by the corpus luteum
- B. the corpus luteum is developing
- C. progesterone is being secreted
- D. oestrogen is at its highest level
Correct Answer: D
Rationale: During the follicular phase, the correct answer is D because it is when the ovaries produce estrogen to stimulate the thickening of the uterine lining. This prepares the uterus for potential implantation of a fertilized egg. In contrast, choice A is incorrect because the corpus luteum is not formed until after ovulation. Choice B is incorrect as the corpus luteum forms after the egg is released. Choice C is incorrect because progesterone is mainly secreted during the luteal phase to maintain the uterine lining.
