Flashcards in Ch 23 Scrotum Deck (31):
1

terminal intratesticular artery arising from the capsular arteries

centripetal artery

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

cremasteric artery

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

cremasteric muscle

4

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

cryptorchidism

5

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

deferential artery

6

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

ejaculatory ducts

7

cyst filled with clear, serous fluid located in the epididymis

epididymal cyst

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

epididymis

9

inflammation of the epididymis

epididymitis

10

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

hematocele

11

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

hydrocele

12

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

mediastinum testis

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

pampiniform plexus

14

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

pudendal artery

15

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

pyocele

16

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

recurrent rami

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

rete testis

18

sac containing the testes and epididymis

scrotum

19

reservoirs for sperm located posterior to the bladder

seminal vesicles

20

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

septa testis

21

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

spermatic cord

22

cyst in the vas deferens containing sperm

spermatocele

23

male gonad that produces hormones that induce masculine features and spermatozoa

testicle

24

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

testicular artery

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

testicular vein

26

inner fibrous membrane surrounding the testicle

tunica albuginea

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

tunica vaginalis

28

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

urethra

29

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

varicocele

30

tube that connects the epididymis to the seminal vesicle

vas deferens

31

junction of the ejaculatory ducts with the urethra

verumontanum
