Ch 23 Scrotum

Question 1

terminal intratesticular artery arising from the capsular arteries

Answer 1

centripetal artery

Question 2

small artery arising from the inferior epigastric artery (a branch of the external iliac artery), which supplies the peritesticular tissue, including the cremasteric muscle

Answer 2

cremasteric artery

Question 3

an extension of the internal oblique muscle that descends to the testis with the spermatic cord; contraction of the cremasteric muscle shortens the spermatic cord and elevates the testis

Answer 3

cremasteric muscle

Question 4

also called undescended testes; testicles remain within the abdomen or groin and fail to descend into the scrotal sac

Answer 4

cryptorchidism

Question 5

arises from the vesicle artery (a branch of the internal iliac artery) and supplies the vas deferens and epididymis

Answer 5

deferential artery

Question 6

connect the seminal vesicle and the vas deferens to the urethra at the verumontanum

Answer 6

ejaculatory ducts

Question 7

cyst filled with clear, serous fluid located in the epididymis

Answer 7

epididymal cyst

Question 8

anatomic structure formed by the network of ducts leaving the mediastinum testis that combine into a single, convoluted epididymal tubule; located on the posterolateral aspect of the testis; the epididymis consists of the head, the body, and the tail; spermatozoa mature and accumulate within the epididymis

Answer 8

epididymis

Question 9

inflammation of the epididymis

Answer 9

epididymitis

Question 10

blood located between the visceral and parietal layers of the tunica vaginalis

Answer 10

hematocele

Question 11

fluid formed between the visceral and parietal layers of the tunica vaginalis

Answer 11

hydrocele

Question 12

central linear structure formed by the convergence of multiple thin septations within the testicle; the septations are invaginations of the tunica albuginea

Answer 12

mediastinum testis

Question 13

plexus of veins in the spermatic cord that drain into the right and left testicular veins; when a varicocele is present, dilation and tortuosity may develop

Answer 13

pampiniform plexus

Question 14

the internal and external pudendal arteries partially supply the scrotal wall and epididymis and occasionally the lower pole of the testis

Answer 14

pudendal artery

Question 15

pus located between the visceral and parietal layers of the tunica vaginalis

Answer 15

pyocele

Question 16

terminal ends of the centripetal (intratesticular) arteries that curve backward toward the capsule

Answer 16

recurrent rami

Question 17

network of channels formed by the convergence of the straight seminiferous tubules in the mediastinum testis; these channels drain into the head of the epididymis

Answer 17

rete testis

Question 18

sac containing the testes and epididymis

Answer 18

scrotum

Question 19

reservoirs for sperm located posterior to the bladder

Answer 19

seminal vesicles

Question 20

multiple septa formed from the tunica albuginea that course toward the mediastinum testis and separate the testicle into lobules

Answer 20

septa testis

Question 21

structure made up of vas deferens, testicular artery, cremasteric artery, and pampiniform plexus that suspends the testis in the scrotum

Answer 21

spermatic cord

Question 22

cyst in the vas deferens containing sperm

Answer 22

spermatocele

Question 23

male gonad that produces hormones that induce masculine features and spermatozoa

Answer 23

testicle

Question 24

artery arising from the aorta just distal to each renal artery; it divides into two major branches, supplying the testis medially and laterally

Answer 24

testicular artery

Question 25

the pampiniform plexus forms each testicular vein; the right testicular vein drains directly into the inferior vena cava, whereas the left testicular vein drains into the left renal vein

Answer 25

testicular vein

Question 26

inner fibrous membrane surrounding the testicle

Answer 26

tunica albuginea

Question 27

membrane consisting of a visceral layer (adherent to the testis) and a parietal layer (adherent to the scrotum) lining the inner wall of the scrotum; a potential space between these layers is where hydroceles may develop

Answer 27

tunica vaginalis

Question 28

small membranous canal that extends from the bladder to the end of the penis

Answer 28

urethra

Question 29

dilated veins in the pampiniform plexus caused by obstruction of the venous return from the testicle

Answer 29

varicocele

Question 30

tube that connects the epididymis to the seminal vesicle

Answer 30

vas deferens

Question 31

junction of the ejaculatory ducts with the urethra

Answer 31

verumontanum
