Question

which of the following statements best characterizes the trigone of the urinary bladder? a. the most superior aspect of the bladder (the dome) b. the base of the bladder, located adjacent to the urethra c. the outermost histologic layer of the bladder, adjacent to the adventitia d. the posterior aspect of the bladder, where the ureters insert into the bladder e. none of the above

Answer 1

The trigone of the urinary bladder is a triangular area at the base, where the ureters insert on the posterior aspect, and the urethral orifice is anterior. (option d)

Step-by-step explanation:

The trigone of the urinary bladder is best characterized as the triangular-shaped area at the base of the bladder, where the two ureters insert on the posterior aspect, and the urethral orifice is on the anterior aspect. Therefore, the correct answer to the student’s question is 'd. the posterior aspect of the bladder, where the ureters insert into the bladder'. The trigone is an important anatomical feature of the bladder responsible for being the entrance for urine coming from the ureters and exit to the urethra.
