The tiny ball of 16 cells found freely
- A. testosterone floating in the uterine cavity is called a
- B. interstitial cell-stimulating ________.
- C. blastocyst
- D. luteinizing hormone
Correct Answer: C
Rationale: The correct answer is C: blastocyst. At this stage of development, the embryo is a hollow ball of cells with an inner cell mass. This structure is called a blastocyst. A is incorrect because testosterone is a hormone, not a cell structure. B is incorrect as it does not describe the early stage of embryonic development. D is incorrect as luteinizing hormone is a hormone involved in the menstrual cycle, not embryonic development.

The male gonads develop in the _______________ before descending down into the scrotum
- A. Pelvic cavity
- B. Peritoneal cavity
- C. Abdominal cavity
- D. Cul- d
Correct Answer: C
Rationale: The correct answer is C: Abdominal cavity. During embryonic development, the male gonads (testes) initially form in the abdominal cavity near the kidneys. They then descend through the inguinal canal into the scrotum. The pelvic cavity (choice A) is below the abdominal cavity, the peritoneal cavity (choice B) is a part of the abdominal cavity, and the cul-de-sac (choice D) is a pouch in the pelvic cavity. The key point is understanding the anatomical path of descent of the male gonads from the abdominal cavity to the scrotum.
Causes of per vaginal bleeding include
- A. Cervical cancer
- B. Endometrial cancer
- C. Leiomyoma
- D. Endometrial carcinoma
Correct Answer: A
Rationale: The correct answer is A: Cervical cancer. Cervical cancer can cause abnormal vaginal bleeding due to the presence of cancerous cells in the cervix. This can lead to spotting or bleeding between periods. Endometrial cancer (choice B) and endometrial carcinoma (choice D) specifically involve the endometrium, not the cervix. Leiomyoma (choice C) refers to uterine fibroids, which can cause heavy menstrual bleeding but are not typically associated with vaginal bleeding outside of menstruation. Therefore, the correct choice is A as it directly relates to per vaginal bleeding, while the other choices are not directly linked to this symptom.
When a male is castrated before puberty, he becomes:
- A. Female
- B. Cretin
- C. Eunuch
- D. Potent
Correct Answer: C
Rationale: The correct answer is C: Eunuch. When a male is castrated before puberty, he becomes a eunuch because castration removes the testes, leading to a lack of testosterone production and loss of male secondary sexual characteristics. This results in a eunuch having a more neutral appearance and lacking the ability to reproduce.
A: Choosing "Female" is incorrect because castration does not change the individual's genetic sex.
B: Selecting "Cretin" is incorrect as cretinism is a condition caused by severe thyroid hormone deficiency, not related to castration.
D: Opting for "Potent" is incorrect as castration leads to the loss of reproductive ability, making the individual infertile.
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.
