1Which structure is the functional filtering unit of the kidney?
A.Nephron
B.Ureter
C.Trigone
D.Detrusor muscle
Explanation: The nephron is the functional unit of the kidney, where blood is filtered and urine is formed. Each kidney contains roughly one million nephrons, comprising the glomerulus and renal tubules.
2The triangular area on the bladder floor bounded by the two ureteral orifices and the internal urethral opening is called the:
A.Detrusor
B.Trigone
C.Urachus
D.Median lobe
Explanation: The trigone is a smooth triangular region on the posterior bladder floor formed by the two ureteral orifices and the internal urethral meatus. It is highly sensitive and an important landmark during cystoscopy.
3Which nerve provides parasympathetic innervation that stimulates detrusor contraction for bladder emptying?
A.Pudendal nerve
B.Hypogastric nerve
C.Pelvic splanchnic nerves
D.Genitofemoral nerve
Explanation: The pelvic splanchnic nerves (S2-S4) carry parasympathetic fibers that release acetylcholine, stimulating detrusor contraction to empty the bladder. This is the basis for cholinergic and anticholinergic drug effects on voiding.
4Sympathetic stimulation via the hypogastric nerve primarily promotes which bladder function?
A.Detrusor contraction
B.Diuresis
C.Ureteral peristalsis
D.Urine storage
Explanation: Sympathetic fibers (T11-L2) via the hypogastric nerve promote urine storage by relaxing the detrusor (beta-3 receptors) and contracting the internal sphincter/bladder neck (alpha-1 receptors). This explains why alpha-blockers ease bladder outlet resistance.
5In the male, the urethra passes through which gland just below the bladder neck?
A.Prostate gland
B.Bulbourethral gland
C.Seminal vesicle
D.Epididymis
Explanation: The prostate gland surrounds the prostatic urethra immediately below the bladder neck. Prostatic enlargement (BPH) therefore commonly compresses the urethra and causes bladder outlet obstruction.
6Which hormone, produced by the kidney, stimulates red blood cell production in the bone marrow?
A.Renin
B.Erythropoietin
C.Aldosterone
D.Calcitonin
Explanation: The kidney produces erythropoietin in response to hypoxia, stimulating erythropoiesis in the bone marrow. Chronic kidney disease reduces erythropoietin and commonly causes anemia.
7Approximately what percentage of the cardiac output do the kidneys receive at rest?
A.About 5%
B.About 40%
C.About 20%
D.About 60%
Explanation: The kidneys receive roughly 20-25% of resting cardiac output, reflecting their major role in filtering blood and maintaining fluid and electrolyte balance. This high flow makes them sensitive to hypotension and hypoperfusion.
8The ureters carry urine to the bladder primarily by which mechanism?
A.Gravity alone
B.Negative bladder pressure
C.Ciliary beating
D.Peristaltic smooth-muscle contractions
Explanation: Ureteral peristalsis, generated by smooth-muscle contractions, actively propels urine from the renal pelvis to the bladder. This is why a ureteral stone obstructing flow causes the waves of colicky pain known as renal colic.
9Which type of epithelium lines the bladder and allows it to stretch as it fills?
A.Transitional epithelium (urothelium)
B.Simple squamous epithelium
C.Stratified keratinized epithelium
D.Pseudostratified ciliated epithelium
Explanation: The bladder is lined by transitional epithelium (urothelium), which can stretch and recoil as bladder volume changes. This specialized lining also forms a barrier against the hyperosmolar, potentially toxic contents of urine.
10The normal adult bladder typically signals a first urge to void at approximately what volume?
A.50-75 mL
B.150-250 mL
C.500-600 mL
D.800-1000 mL
Explanation: A first sensation to void typically occurs at roughly 150-250 mL, with a strong urge near 400-500 mL and functional capacity around 400-600 mL. Knowing these landmarks helps interpret bladder diaries and urodynamic studies.
