Bidder's canal receives __________.
- A. Eggs
- B. Sperms
- C. Ammonia
- D. Oxygenated blood
Correct Answer: D
Rationale: The correct answer is D: Oxygenated blood. Bidder's canal is a part of the male reproductive system and functions to transport oxygenated blood to the testicles. This is essential for maintaining the temperature required for sperm production. Eggs (A) are not transported through Bidder's canal as it is specific to male reproductive functions. Sperms (B) are produced in the testicles but are not transported through Bidder's canal. Ammonia (C) is a waste product and not involved in the circulation within the male reproductive system.

Which of the following is a steroid?
- A. FSH
- B. LH
- C. estrogen
- D. GnRH
Correct Answer: C
Rationale: The correct answer is C: estrogen. Estrogen is a type of steroid hormone derived from cholesterol. Steroids are a specific group of lipids characterized by a particular molecular structure. Estrogen plays a vital role in the development and regulation of the female reproductive system.
Choice A, FSH, and choice B, LH, are both peptide hormones, not steroids. Peptide hormones are made up of amino acids and are not derived from cholesterol.
Choice D, GnRH, is also a peptide hormone that regulates the release of other hormones in the body, particularly in the reproductive system.
In summary, estrogen is the only steroid hormone among the options provided, making it the correct choice.
Discharge of pus or mucus from the uterus is called as:
- A. Dysmenorrhea
- B. Hypomenorrhea
- C. Metrorrhea

Dysmenorrhea (A) is severe menstrual pain, Hypomenorrhea (B) is abnormally light menstrual flow, and Oligomenorrhea (D) is infrequent or light menstrual periods. Therefore, based on the definition provided in the question, Metrorrhea is the correct term for the discharge of pus or mucus from the uterus.
Inflammation of bone and bone marrow secondary to infection is called?
- A. Osteitis.
- B. Osteochondritis.
- C. Osteom
- D. Osteomyelitis

"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.
Why is rupturing of the hymen not considered a confirmation of loss of virginity?

- B. Because the hymen can be perforated during physical activity, insertion of a tampon, or pelvic examination.
- C. Because the hymen is ruptured the first time a person urinates.
- D. Because the hymen is very delicate and may be ruptured even when running or doing strenuous exercises.
Correct Answer: B
Rationale: The hymen can be perforated by various non-sexual activities, making it an unreliable indicator of virginity.

A: Blastocyst is a later stage of development after the zygote has undergone several cell divisions.
C: Fetus refers to the later stages of development when the embryo has developed recognizable features.
D: Embryo is the stage after the zygote when the cells start to differentiate into different tissues and organs.
