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.

Which of the following structures is often referred to as the bag of water?
- A. Urinary bladder
- B. Gall bladder
- C. Amniotic sac
- D. Uterus
Correct Answer: C
Rationale: The correct answer is C: Amniotic sac. This structure is often referred to as the "bag of water" because it is a fluid-filled sac that surrounds and protects the developing fetus during pregnancy. The amniotic sac provides cushioning and maintains a stable environment for the fetus to grow. It is essential for the baby's development and acts as a barrier against infections.
Choice A: Urinary bladder - This structure is responsible for storing urine and is not typically referred to as the bag of water.
Choice B: Gall bladder - This organ stores bile produced by the liver and aids in digestion, not related to pregnancy or fetal development.
Choice D: Uterus - While the uterus is involved in pregnancy and fetal development, it is not commonly referred to as the bag of water.
The mature follicle is also called a _____.
- A. Graafian follicle
- B. granulosa cell
- C. primary follicle
- D. secondary follicle
Correct Answer: A
Rationale: The correct answer is A: Graafian follicle. The mature follicle is called a Graafian follicle because it is the final stage of follicle development before ovulation. It is characterized by a fluid-filled cavity containing the oocyte. The other choices are incorrect because a granulosa cell is a type of cell found in the follicle wall, a primary follicle is an immature follicle, and a secondary follicle is an intermediate stage between the primary and Graafian follicle.
What is the source of the male sex hormones?
- A. epididymis
- B. vas deferens
- C. seminiferous tubules
- D. interstitial cells
Correct Answer: D
Rationale: The correct answer is D: interstitial cells. Interstitial cells, also known as Leydig cells, are located in the testes and are responsible for producing male sex hormones, primarily testosterone. The other choices, A: epididymis, B: vas deferens, and C: seminiferous tubules, are not directly involved in the production of male sex hormones. The epididymis is a structure for sperm maturation, the vas deferens is a duct for transporting sperm, and the seminiferous tubules are responsible for sperm production through spermatogenesis. Therefore, interstitial cells are the source of male sex hormones, making choice D the correct answer.
Corpus luteum;
- A. is generated as a result of ovulation;
- B. secretes estrogens;
- C. secrets progesterone;
- D. secrets low amounts of testosterone
Correct Answer: C
Rationale: The corpus luteum is formed from the ruptured follicle after ovulation. It secretes progesterone, which is crucial for preparing the uterus for implantation and maintaining early pregnancy. Progesterone helps thicken the uterine lining and supports embryo development. Estrogens are mainly produced by the ovaries, not the corpus luteum. Testosterone is primarily produced by the adrenal glands and testes, not the corpus luteum. Therefore, choice C is correct as it accurately describes the main hormone secreted by the corpus luteum.
