Deck 18: The Prostate Gland and Seminal Vesicles

Question 1

Which statement is NOT true about the seminal vesicles?

A) They are paired glands.
B) They are posterior to the urinary bladder and inferior to the prostate.
C) Each gland empties into the distal ductus (vas) deferens.
D) They help form the ejaculatory duct.

Answer 1

B
The seminal vesicles are paired glands that lie posterior to the urinary bladder and superior to the prostate. Each gland joins with the distal portion of the corresponding ductus (vas) deferens to form two ejaculatory ducts.

Question 2

The largest portion of the glandular prostate is the

A) central zone.
B) transition zone.
C) periurethral zone.
D) peripheral zone.

Answer 2

D
The peripheral zone comprises 70% of the glandular prostate.

Question 3

Denonvilliers' fascia

A) is an interior covering for the prostate gland.
B) is the external coating for the seminal vesicles.
C) lies between the prostate and the rectum.
D) lines the external wall of the urinary bladder.

Answer 3

C
The prostate lies behind the symphysis pubis and is separated posteriorly from the rectum by two layers of Denonvilliers' fascia.

Question 4

The seminal vesicles join with the ductus deferens to form the ejaculatory ducts. ____

Question 5

The area close to the center of the prostate is called the

A) anterior fibromuscular region.
B) verumontanum.
C) central zone.
D) regional stroma.

Question 6

The peripheral zone comprises what percentage of the glandular prostate?

A) 20%
B) 5%
C) 30%
D) 70%

Question 7

Which areas are posterior to the periurethral zone?

A) Central zone, anterior fibromuscular region, and transition zone
B) Central zone, transition zone, and verumontanum
C) Central zone, peripheral zone, and verumontanum
D) Central zone, peripheral zone, and seminal vesicles

Question 8

Semen is composed of

A) 60% alkaline fructose, 13% to 33% alkaline fluid, and sperm.
B) 13% to 33% alkaline fructose, 70% alkaline fluid, and sperm.
C) 70% alkaline fructose, 13% to 33% sperm, and acidic fluids.
D) 60% sperm, 13% to 33% alkaline fluid, and fructose.

Question 9

When zones are compared on ultrasound, the peripheral zone may appear more echogenic than which structure(s)?

A) Central zone
B) Transition zone
C) Periurethral tissues
D) All of the above

Question 10

The prostate weighs about

A) 5g
B) 10g
C) 20g
D) 40g

Question 11

In a scan of the prostate and seminal vesicles, the prostate appears

A) hypoechoic to the seminal vesicles.
B) isoechoic to the seminal vesicles.
C) hyperechoic to the seminal vesicles.
D) anechoic to the seminal vesicles.

Question 12

Alkaline, viscous fructose is produced by the prostate gland. ____

Question 13

When imaging or describing the glandular prostate, the best technique to describe the prostate is to use

A) regions.
B) zones.
C) anterior and posterior terminology.
D) medial and lateral terminology.

Question 14

The prostate is supported by

A) Denonvilliers' fascia.
B) the seminal vesicles and ejaculatory ducts.
C) the symphysis pubis.
D) the obturator internus and levator ani muscles.

Question 15

Only alkaline fluid is produced by the seminal vesicles. ____

Question 16

The anterior fibromuscular region, or stroma,

A) is anterior to most of the zonal anatomy.
B) is more clinically significant than the posterior glandular prostate.
C) accounts for most of the weight of the prostate.
D) lies adjacent to the seminal vesicles.

Question 17

The periurethral tissues can easily be differentiated from the anterior fibromuscular stroma. ______
