1

Where are the kidneys and proximal ureters?

Abdomen

2

Where are the distal ureters, bladder and proximal urethra?

Pelvis

3

Where is the distal urethra?

Perineum

4

Where do the ureters pass?

From the retroperitoneum, through the false pelvis and into the true pelvis

5

Where is the false pelvis?

The false pelvis is from the iliac crests to the pelvic inlet
The false pelvis is part of the abdominal cavity

6

Where is the true pelvis?

From the pelvic inlet to the pelvic floor

7

Where is the bladder?

Pelvic cavity

8

Pelvic floor muscles?

Levator ani

9

Urethra passes through where?

Through the pelvic floor and into the perineum

10

Where do the ureters pass in relation to the common iliac vessels?

The ureters pass anterior to the common iliac vessels to enter the pelvis

11

At what level to the ureters turn medially to enter the posterior aspect of the bladder?

The ureters turn medially at the level of the ischial spine to enter the posterior aspect of the bladder

12

In which direction do the ureters enter the posterior bladder wall?

The ureters enter the posterior bladder wall in an inferomedial direction
-helps prevent reflux of urine back into the ureters when the bladder contracts

13

Most inferior part of the male peritoneal cavity?

Rectovesicle pouch

14

Most inferior par of the female pertioneal cavity?

Rectouterine puch

15

What is the vesico-uterine pouch?

The pouch between the bladder and the uterus

16

The ureter in reference to the vas deferens?

The ureter runs inferiorly to the vas deferens

17

"water under the bridge"

In females, the ureter enters the bladder by passing UNDER the uterine artery

18

Uterine artery is a branch of what?

The uterine artery is a branch of the internal iliac

19

What gives branches to the pelvic organs, gluteal region and perinuem?

The internal iliac gives branches to the pelvic organs, gluteal region and perineum

20

Arteries to the bladder?

Vesical arteries
-the postatic arteries are often branches from the vesical arteries

21

Middle rectal artery is a branch of which artery?

The internal iliac

22

Bladder wall formed by which muscle?

Detrusor muscle

23

In the male bladder, which muscle also forms the internal urethral sphincter muscle and what is the function of this sphincter?

The detrusor muscle forms the internal urethral sphincter muscle and this contracts during ejaculation to prevent retrograde ejaculation

24

An empty bladder? where does it lie?

An empty bladder lies within the pelvis
The peritoneum covers its superior surface only

25

A full bladder can extend out of where?
-Where does the superior part lie?

A full bladder can extend out of the pelvis
-The superior part lies superior to the pubic bone
-peritoneum still only covers the superior surface

26

2 routes of catheterising a patient?

Urethral (more common)
Suprapubic (through anterior abdominal wall, avoiding peritoneal cavity)

27

Roughly how long is the female urethra?

The female urethra is approximately 4cm long

28

How long is the male urethra?

20cm long

29

Where is the spongy urethra?

Within the corpus spngiosum

30

What type of muscle makes the external urethral sphincter?

Skeletal muscle

31

Where is the spongy urethra?

Within the corpus spongiosum

32

What travels through the spermatic cord?

Testicular artery
Testicular vein
Vas deferens
Lymphatic vessels
Nerves (autonomic--> vas deferens, somatic --> cremaster muscle)

33

Nerve supply to vas deferens

Autonomic

34

Nerve supply to cremaster muscle?

Somatic

35

The sac that the testis sit within?

The tunica vaginalis

36

Excess fluid within the tunica vaginalis?

Hydrocele

37

Where can the epididymis be palpated?

Epididymis can be palpated at posterior aspect of testis

38

Where can the vas deferens be palpated?

The vas deferens can be palpated within the spermatic cord
-in scrotum, superior to testis

39

The route of sperm?

Vas deferens passes superiorly in spermatic cord, to deep inguinal rung
-at deep inguinal ring, the vas deferens turns medially into the pelvis
-it then travels posterior to bladder

40

Through which ducts do the glandular secretions from the prostate drain into the prostatic urethra?

Prostatic ducts

41

Ejaculatory duct

Combined duct of the vas deferens and the duct from the seminal gland

42

Most cancers arise from which part of the prostate gland?

Most cancers arise from the peripheral zone of the postate gland

43

How can you feel the peripheral part of the prostate gland?

You can feel the peripheral zone of the porstate on rectal examination

44

Where does the root of the penis attach to?

The ischium of pelvis

45

What does the corpus cavernosum transmit?

The deep arteries of the penis

46

What does the corpus spongiosum transmit?

The spongy urethra
