penis overview

Buck fascia

a dense fibrous tissue that covers the penis

the inner penis is composed of these 3 cylindrical tissue components:

• a single corpous spongiosum

• paired corpora cavernosa

the urethra is housed within the:

corpus spongiosum, which is situated ventrally

the paired cavernosa is situated:

dorsally

the tunica albuginea surrounds the:

corpora cavernosa and partially covers the corpus spongiosum

all 3 corpora are covered by:

Buck fascia

the vascular supply to the penis begins at the:

internal pudendal artery, which is a tributary of the internal iliac artery

the internal pudendal arteries branch into the:

deep artery of the penis, the penile artery

the deep artery of the penis provides the blood supply to the:

corpora cavernosa

the cavernosal arteries are located within the:

corpora cavernosa bilaterally

when sexual arousal occurs, the arteries within the penis become engorged with blood, causing:

the compression of the adjacent veins, preventing venous drainage, and resulting in an erection

what transducer is used to image the penis?

a high-frequency linear transducer

In transverse, the singular corpus spongiosum, which contains the urethra, will be seen:

ventrally

In transverse, the paired corpora cavernosa will be seen:

dorsally

sonographic appearance of the spongiosum in transverse:

will be elliptical in shape and consist of medium- to low-level echoes

sonographic appearance of the cavernosa in transverse:

will appear similar in echogenicity to the spongiosum, but have a more oval shape

sonographic appearance of the tunica albugniea:

• highly echogenic

• can be seen separating and covering the corpora
