Flashcards in Anatomy of the Urinary Tract Deck (13):
1

How do the ureters enter the bladder?

In an inferomedial direction obliquely through the wall

2

What causes the one-way flap valve from the ureters to the bladder?

The bladder muscular wall as the ureters pass into the bladder

3

Major differences in male and female urethra:

Male: external and internal sphincter, longer
Female: external sphincter, shorter

4

What are the three parts of the male urethra?

1.) Prostatic
2.) Intermediate (membranous sphincter; external sphincter)
3.) Penile

5

What does the posterior aspect of the male bladder rest on?

The rectum

6

What makes it difficult to catheterize male patients?

Males have two 90 degree bends in the urethra

7

What are para-urethral glands in females?

Glands that secrete low pH inhibiting growth of bacteria

8

Why do calculi (kidney stones) in the ureters transmit pain sensation to referred areas of the body only?

They do not have sensory nerves only autonomics sending AP into the visceral afferents

9

Parasympathetic branches to ureter:

S2-S4

10

Sympathetic fibers to the ureter:

T10-L2

11

What is the utricle?

A blind sac found in the middle of the prostate between two ejaculatory ducts

12

What is different about the trigone than the rest of the bladder?

It does not have transitional epithelium (therefore does not phagocytize like the bladder transitional epithelium); very sensitive to stretch

13

Where does the empty bladder lie entirely?

Within the true pelvis (not above the pubic symphysis at all)
