Regarding spermatogenesis, we can state the following:
- A. it occurs at the level of testicular interstitial cells;
- B. it occurs at the level of the Leydig cells;
- C. it occurs at the level of the convoluted seminiferous tubules;
- D. it begins around the age of 14;
Correct Answer: C
Rationale: The correct answer is C because spermatogenesis occurs within the convoluted seminiferous tubules of the testes. This is where sperm cells are produced through a series of cell divisions and maturation processes. Choice A is incorrect as spermatogenesis does not occur at the level of testicular interstitial cells, which are responsible for hormone production. Choice B is also incorrect as Leydig cells are responsible for testosterone production, not sperm production. Choice D is incorrect as spermatogenesis actually begins during puberty, typically around the age of 12-13, not specifically at the age of 14.

Which of the following has no homolog in the female?
- A. penis
- B. scrotum
- C. prostate
- D. bulbourethral glands
Correct Answer: B
Rationale: The correct answer is B: scrotum. The scrotum is a male-specific structure that houses the testes, which are responsible for producing sperm. In females, there is no homologous structure that serves the same function as the scrotum. The other choices (A: penis, C: prostate, D: bulbourethral glands) have homologous structures in females (clitoris, Skene's glands, and Bartholin's glands, respectively). This differentiation is based on the embryological development of male and female reproductive structures.
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.
Inflammation of vertebra is
- A. Spondylitis.
- B. Spondylolisthesis.
- C. Spondylosis.
- D. Spondylopathy
Correct Answer: A
Rationale: Rationale:
1. Spondylitis refers to inflammation of the vertebrae, making it the correct choice.
2. Spondylolisthesis is the anterior displacement of a vertebra, not inflammation.
3. Spondylosis is degenerative changes in the spine, not inflammation.
4. Spondylopathy is a general term for any spinal disease, not specific to inflammation.
When sexual feelings occur, it is important to
- A. consciously choose to act responsibly
- B. go to a quiet place and talk about what you are feeling with your partner
- C. explore the feelings and do what feels best
- D. see a doctor
Correct Answer: A
Rationale: The correct answer is A because it emphasizes the importance of consciously choosing to act responsibly when sexual feelings arise. This involves considering the consequences, respecting boundaries, and making informed decisions. Going to a quiet place to talk (B) may not address responsible actions. Exploring feelings and doing what feels best (C) may lead to impulsive or harmful choices. Seeing a doctor (D) is not necessary for regular sexual feelings. A conscious and responsible approach promotes healthy relationships and personal well-being.
Shin bone is also known as
- A. Femur
- B. Tibia
- C. Fibula
- D. Patella
Correct Answer: B
Rationale: The correct answer is B: Tibia. The shin bone is commonly referred to as the tibia. This bone is located on the inner side of the leg and is the larger of the two lower leg bones. The femur (A) is the thigh bone, the fibula (C) is the smaller of the two lower leg bones, and the patella (D) is the kneecap. Therefore, the tibia is the correct answer as it specifically refers to the shin bone.
