The primary sex organ in the male is the _____.
- A. penis
- B. testis
- C. scrotum
- D. epididymis
Correct Answer: B
Rationale: The correct answer is B: testis. The testis is the primary male sex organ responsible for producing sperm and testosterone. It is located within the scrotum. The penis (choice A) is the male reproductive organ used for sexual intercourse but is not the primary sex organ. The scrotum (choice C) is the external sac that houses the testes but is not the primary sex organ itself. The epididymis (choice D) is a coiled tube located on the testis where sperm mature and are stored, but it is not the primary sex organ.

The process of release of ovum from the ovary is termed as
- A. Dessication
- B. Ovulation
- C. Fenestration
- D. Maturation
Correct Answer: B
Rationale: The correct answer is B: Ovulation. Ovulation is the process of the release of the mature egg (ovum) from the ovary. During ovulation, the egg is released into the fallopian tube where it can potentially be fertilized by sperm. Dessication (A) refers to the process of drying out, Fenestration (C) is the creation of an opening or hole, and Maturation (D) is the process of becoming mature. Therefore, the correct term specifically related to the release of the egg from the ovary is ovulation.
Regarding gross anatomy of male reproductive system
- A. Dartos muscle is responsible to raise and lower the testes
- B. Ductus deferens penetrate the prostate gland to connect with prostatic urethra
- C. Anterior lobe of prostate gland is the main glandular tissue
- D. Buck's fascia encloses body of penis
Correct Answer: B
Rationale: The correct answer is B because the ductus deferens penetrates the prostate gland to connect with the prostatic urethra, forming the ejaculatory duct. This allows for the transport of sperm from the epididymis to the urethra during ejaculation.
A: Dartos muscle is responsible for wrinkling the scrotal skin but not raising and lowering the testes.
C: The anterior lobe of the prostate gland mainly consists of fibromuscular tissue, not glandular tissue.
D: Buck's fascia surrounds the corpora cavernosa and the corpus spongiosum of the penis, not the body of the penis itself.
Each menstrual cycle is considered as a period of ________
- A. 28 days
- B. 30 days
- C. 42 days
- D. 14 days
Correct Answer: A
Rationale: The correct answer is A: 28 days because the average menstrual cycle length is typically around 28 days, although it can vary. The menstrual cycle consists of different phases such as menstruation, follicular phase, ovulation, and luteal phase, which collectively last around 28 days on average. Choice B (30 days), C (42 days), and D (14 days) are incorrect because they do not represent the typical duration of a menstrual cycle. It's important to note that individual variations in cycle length are common, but 28 days is considered a standard reference point.
Which of the following statements is incorrect.
- A. a female has approximately 2-4 million oocytes at birth
- B. a female has approximately 6 million oogonia during fetal development
- C. a female ovulates about 2,000 to 4,000 oocytes during her life
- D. only approximately 1-5 oocytes are fertilized
Correct Answer: C
Rationale: The correct answer is C because a female actually ovulates only about 400-500 oocytes during her lifetime, not 2,000 to 4,000. This is due to the process of follicular atresia where many oocytes are lost before ovulation. Choice A is correct as females have a finite number of oocytes at birth. Choice B is correct as oogonia differentiate into primary oocytes during fetal development. Choice D is incorrect as typically only one oocyte is fertilized during each menstrual cycle.
