1

The urinary bladder is slightly lower in what gender?

Females

2

When the bladder is empty, it lies in what part of the body?

Entirely within the pelvis resting against the pubis and adjacent pelvic floor

3

When the bladder is filling, it moves to which area of the body?

Rises into the abdomen and may reach the level of the umbilicus

4

At birth, what is the shape and location of the bladder?

Spindle-shaped and mostly in the abdomen

5

What are the surfaces of the bladder?

Superior, left inferolateral, right inferolateral, fundus (base)

6

What surfaces of the bladder meet to form the apex?

Superior and the two inferolateral surfaces in front

7

What surfaces meet to form the neck of the bladder?

Inferolateral surfaces and fundus

8

What is the path of the ureters?

Subperitoneally along the lateral wall of the pelvis and enter the bladder at its fundus

9

Peritoneum overlies which surface of the bladder?

Superior surface

10

Why does the position of the uterus cause frequent micturition during pregnancy?

Due to the body of the uterus overlying the bladder in females

11

What is the retropubic space?

U-shaped space between the pubis and bladder that contains a retropubic fat pad

12

Why do some long distance runners notice blood in their urine after a long run?

Retropubic fat pad sometimes is insufficient and repetitive trauma occurs from the bladder hitting the pubic symphysis during the run

13

What are the two ligaments that function to hold the bladder in place?

Puboprostatic (pubovesical) ligament and lateral ligament of the bladder

14

What does the puboprostatic ligament do?

Attaches the prostate gland (or neck of the bladder in the female) to the pubis

15

What does the lateral ligament of the bladder do?

Passes from the base of the bladder to the rectovesical fold (males) or rectouterine fold (females)

16

What is the smooth triangular structure located on the posterior and inferior wall of the bladder?

Trigone

17

What is the importance of the flap-valve of the ureter?

Prevents reflux of urine heading back to the kidneys

18

What happens to the ureter when the bladder is full and also during micturition?

Ureter is compressed (flap-valve)

19

What opening of the trigone is located below and in front?

Internal urethral orifice

20

What openings of the trigone are located above and behind?

Ureteric orifices

21

How do the ureters travel within the bladder?

Obliquely in an inferomedial direction

22

What is the feature that extends between each of the ureteric orifices?

Interureteric crest

23

What is the median ridge which extends above and behind the internal urethral orifice?

Uvula of bladder

24

What is the bundle of smooth muscle which lies within the wall of the bladder?

Detrusor muscle

25

What is the circular layer of smooth muscle which surrounds the neck of the bladder in males?

Internal urethral sphincter

26

What is the purpose of the internal urethral sphincter in males?

Prevents reflux of semen into the bladder during ejaculation

27

The internal urethral sphincter is not present in which gender?

Females

28

What arteries make up the blood supply of the urinary bladder?

Superior and inferior vesical arteries, vaginal artery

29

What makes up the venous blood supply of the urinary bladder?

Prostatic (male) or vesical (female) plexus of veins

30

Where do the prostatic (male) or vesical (female) plexus of veins empty into?

Internal iliac vein
