Questions On The Urinary System Questions
Question 1 of 5
The arteriolar recta spuria arise from
Correct Answer: D
Rationale: Arteriola recta spuria (false) arise from efferent arterioles not interlobar, interlobular, or afferent. This specifies medullary supply, critical for countercurrent, contrasting with other origins.
Question 2 of 5
Filtrate in the distal convoluted tubule:
Correct Answer: A
Rationale: Filtrate in the distal convoluted tubule (DCT) has just exited the loop of Henle not pre-loop (PCT), pre-glomerulus (blood), or pre-PCT (glomerulus). The loop concentrates filtrate before DCT fine-tunes it, placing it post-loop in the nephron sequence. This clarifies filtrate progression, key for nephron function, contrasting with earlier stages.
Question 3 of 5
The mesonephric tubules in male gives:
Correct Answer: A
Rationale: In males, mesonephric tubules form vasa efferentia (testis to epididymis) not epididymis duct, vas deferens, ejaculatory duct (from mesonephric duct), or all. This specifies tubule fate, key for reproductive anatomy, contrasting with duct derivatives.
Question 4 of 5
The caudal somites migrate to give the following except:
Correct Answer: D
Rationale: Caudal somites form genital tubercle, swellings, external sphincter, and abdominal wall not internal anal sphincter (splanchnic mesoderm). This excludes visceral muscle, key for somitic roles, contrasting with included derivatives.
Question 5 of 5
The definitive urogenital sinus in male gives rise to:
Correct Answer: D
Rationale: Definitive urogenital sinus forms lower prostatic, membranous, and most spongy urethra not just membranous/spongy; 'all' is correct. This specifies sinus role, key for male urethra, contrasting with limited parts.
