Disorders in Reproductive System Questions
Question 1 of 5
Which of the following is the male pattern of development “master switch” gene?
Correct Answer: A
Rationale: The correct answer is A: SRY. The Sex-determining Region Y (SRY) gene is the master switch for male development. It initiates the development of male gonads. Choice B, MIS, is a hormone involved in female reproductive development. Choices C and D, XYY and XXY, are genetic conditions related to male chromosomal variations and are not the master switch gene for male development.
Question 2 of 5
Congenital opening of the male urethra on the undersurface of the penis is called:
Correct Answer: A
Rationale: Step-by-step rationale: 1. Hypospadias is the congenital opening of the male urethra on the undersurface of the penis. 2. This condition results from incomplete closure of the urethral folds during fetal development. 3. Phimosis is the inability to retract the foreskin over the glans penis. 4. Epispadias is the congenital opening of the male urethra on the upper surface of the penis. 5. Herpes is a viral infection causing painful sores, but not related to the location of the urethral opening. Summary: Hypospadias is correct as it matches the description of the condition, while the other choices describe different conditions not related to the location of the urethral opening.
Question 3 of 5
The 16 feet long tube that is coiled and located above the
Correct Answer: A
Rationale: The correct answer is A: epididymis. The epididymis is a coiled tube located on the back of each testicle, approximately 16 feet long when unraveled. It plays a crucial role in sperm maturation and storage. The other choices, B: Vas deferens, C: Urethra, and D: Ureter, are incorrect as they are not coiled tubes located above the testicles and do not have the same function as the epididymis in sperm development and storage.
Question 4 of 5
Soft spots that refers to unossified areas in an infants skull is termed as
Correct Answer: C
Rationale: The correct answer is C: Fontanelle. Fontanelles are soft spots in an infant's skull where the bones have not yet fully fused. They allow for the baby's brain to grow and accommodate the rapid brain development during the early months of life. Sulcus refers to a groove or furrow, sinus is a cavity within a bone, and suture is the line where two bones meet. These terms do not specifically refer to the unossified areas in an infant's skull, making them incorrect choices.
Question 5 of 5
The depression or socket in the pelvic bone into which the head of the femur articulates is called
Correct Answer: D
Rationale: The correct answer is D: Acetabulum. The acetabulum is the depression in the pelvic bone where the head of the femur articulates. This articulation forms the hip joint. The glenoid fossa (A) is found in the scapula and articulates with the head of the humerus, not the femur. The mandibular fossa (B) is located in the temporal bone and articulates with the mandible, not the femur. The jugular fossa (C) is a groove in the temporal bone for the internal jugular vein, not related to the femur articulation. Therefore, the correct choice is D as it accurately describes the anatomical structure where the femur articulates with the pelvic bone.
