the part of the prostate that is in contact with the bladder is the

base

the anterior fibromuscular region or stroma

is anterior to most of the zonal anatomy

Denonvillier's fascia

lies between the prostate and the rectum

what is the echogenicity of the septum penis

low level echoes

Normal intratesticular arterial flow should exhibit

low resistance waveform

echogenicity of the epididymis

medium level echoes

what is the echogenicity of the corpora carvenosa

medium level echoes

the temperature of the testes is regulated by the

pampiniform plexus

the largest portion of the glandular prostate is the

peripheral zone

the epididymal head is connected to which portion of the testis

superior

the peripheral zone compromises what percentage of the glandular prostate

70%

testicular parenchyma on ultrasound is

heterogenous

echogenicity of the cavernosal arterial walls

high echogenicity

echogenicity of tunica albuginea

high echogenicity

excess fluid between the two layers of the tunica vaginalis is termed

hydrocele

on a sonogram of the prostate and seminal vesicles, the prostate normally appears

hyperechoic to the seminal vesicles

the normal AP diameter of the epididymal head is

10 to 12 mm

Semen is composed of

60% alkaline fructose, 13% to 33% alkaline fluid, and sperm

About 60% of semen is composed of

alkaline fluid rich in fructose, produced by the seminal vesicles.

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

all of these

the main arterial blood supply of the penis includes the

deep artery of the penis, bulbourethral artery, and dorsal artery

the periurethral tissues can easily be differentiated from the anterior fibromuscular stroma

false

the prostate atrophies due to benign changes and infection

false

the transabdominal approach is superior for scanning the seminal vesicles and prostate compared to the transrectal approach

false

which statement is incorrect about the seminal vesicles

they are posterior to the urinary bladder and inferior to the prostate

normal serum prostatic specific antigen is less than 4

true

Convoluted seminiferous tubules connect to straight tubules, which empty into the

tunica albuginea

the penis is composed of

two corpora cavernosa dorsolaterally and the corpus spongiosum midventrally.

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

verumontanum

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

zones
