Which hormone thickens the lining of the uterus?
- A. FSH
- B. estrogen
- C. LH
- D. progesterone
Correct Answer: B
Rationale: The correct answer is B: estrogen. Estrogen is responsible for thickening the lining of the uterus during the menstrual cycle in preparation for implantation of a fertilized egg. Follicle-stimulating hormone (FSH) stimulates the growth of ovarian follicles. Luteinizing hormone (LH) triggers ovulation. Progesterone helps maintain the uterine lining during the second half of the menstrual cycle. Estrogen plays a key role in the initial thickening of the uterine lining, making it the correct choice.

- A. spermatic cord
- B. spermatogonia
- C. testis
- D. oogonia
Correct Answer: B
Rationale: The correct answer is B: spermatogonia. Spermatogonia are the cells within the seminiferous tubules of the testes that give rise to sperm cells. Testosterone is produced by Leydig cells, not spermatogonia. A is incorrect because the spermatic cord does not produce testosterone. C is incorrect as the testis is the overall organ where the seminiferous tubules are located. D is incorrect as oogonia are female germ cells found in the ovaries, not the testes.
The ovary connects by ligaments to:
- A. the uterus;
- B. the Fallopian tubes;
- C. the rectum;
- D. the pelvic walls;
Correct Answer: A
Rationale: The correct answer is A: the uterus. The ovary connects to the uterus via ligaments called ovarian ligaments. This connection is essential for the transfer of eggs from the ovary to the uterus during the menstrual cycle and for providing support to the ovary. The other choices are incorrect as the ovary does not directly connect to the Fallopian tubes (B), rectum (C), or pelvic walls (D) via ligaments. The connection to the uterus is crucial for reproductive functions and maintaining the structural integrity of the female reproductive system.
This connects the ovary to the uterus.
- A. Vagina
- B. Cervix
- C. Fallopian tube
- D. perineorrhaphy
Correct Answer: B
Rationale: The correct answer is B: Cervix. The cervix is the narrow passage that connects the uterus to the vagina. It acts as a barrier between the uterus and the outside environment. The other choices are incorrect because: A: Vagina is the birth canal and does not directly connect the ovary to the uterus. C: Fallopian tube connects the ovary to the uterus but does not directly attach to it. D: Perineorrhaphy is a surgical procedure to repair the perineum and is not related to connecting the ovary to the uterus.
