BIOD 152 MODULE 7 EXAM
1. Discuss two features of the bladder that allow for expansion.
Answer: (Any two ofthe following are acceptable responses)
1- The muscular wall stretches and thins allowing the bladder to store larger amountsof urine
without a significant rise in internal pressure.
2- Rugae (folds in the bladder wall) also extend to help the capacity of the bladderinternally.
3- Transitional epithelium cells are specialized to enable cellular expansion to absorbfluid.
2. A patient was just placed under general anesthesia. He is now awake and telling you he is
having a hard time excreting urine.What is most likely causingthe difficulty?
A. Incontinence due to stroke
B. Incontinence due to dementia
C. Urinary retention due to spinal cord injury
D. Bladder outlet obstruction
E. Urinary retention due to slowed detrusor muscle
Answer: Urinary retention due toslowed detrusor muscle
3. An elderly male with dementia frequently micturates at inappropriate times(during meals,
not in the toilet). What is most likely causing the difficulty?
A. Incontinence due to end stage dementia
B. Incontinence due to swollen seminal vesicle
C. Urinary retention due to not enjoying meals
D. Urinary retention due to enlarged prostate
E. Hematuria due to diabetes
Answer: Incontinence due to end stage dementia
4. An elderly male is unable to micturate. What is most likely causing thedifficulty?
A. Incontinence due to end stage dementia
B. Incontinence due to swollen seminal vesicle
C. Urinary retention due to spinal cord injury
D. Urinary retention due to enlarged prostate
E. Urinary retention is the inability to expel stored urine.
F. Hematuria due to diabetes
Answer: Urinary retention due to enlarged prostate
5. This is the smallest region of the male urethra.
A. Spongy
B. Prostatic
C. Membranous
D. Ejaculatory duct
E. Ureters
, Answer: Membranous
6. This region of the male urethra exits the bladder.
A. Spongy
B. Prostatic
C. Membranous
D. Ejaculatory duct
E. Ureters
Answer: prostatic
7. For micturition to occur
Answer: The internal sphincter relaxes and the externalsphincter relaxes
8. This region of the male urethra exits the body.
A. Spongy
B. Prostatic
C. Membranous
D. Ejaculatory duct
E. Ureters
Answer: Spongy
9. Describe the difference between the two types of nephrons.
Answer:
- Corticalnephrons: cortex region of kidney, except a portion of their loop of Henle which
extends into the medulla
- Juxtamedullary nephrons: pass deep into the medulla because of their location andlonger loops
of Henle
10. What causes the extremely high blood pressure in the glomerular capillaries?
Answer: The afferent arteriole, which is fed by the interlobular artery, is much larger in
diameter than the efferent arteriole. The difference in diameter causes an extremelyhigh blood
pressure in the glomerular capillaries.
11. Micturition can be controlled consciously because of:
A. Voluntary control over the internal sphincter
B. Involuntary control over the internal sphincter
C. Voluntary control over the external sphincter
D. Involuntary control over the external sphincter
Answer: Voluntary control over theexternal sphincter
12. This is the blood pressure driving fluid out of the capillaries
A. Colloid osmotic pressure
B. capsular pressure
C. Net filtration pressure
