Answer to Question 1

Ans:
C

Feedback:

The detrusor muscle is the muscle of micturition. When it contracts, urine is expelled from the bladder. External sphincter is a circular muscle that surrounds the urethra distal to the base of the bladder and can stop micturition when it is occurring. Trigone is a smooth triangular area that is bounded by the ureters and the urethra. Urinary vesicle is another name for the bladder.

Answer to Question 2

Ans:
A, B, C

Feedback:

Renal hypoplasia, cystic dysplasia, and horseshoe kidney are more common diagnoses in infants. Renal cell carcinoma is not a congenital condition or one that often manifests in infancy. Urine-filled dilation of renal pelvis associated with atrophy of the kidney is a description of hydronephrosis.
