front 1 centripetal artery | back 1 terminal intratesticular artery arising from the capsular arteries |
front 2 cremasteric artery | back 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 |
front 3 cremasteric muscle | back 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 |
front 4 cryptorchidism | back 4 also called undescended testes; testicles remain within the abdomen or groin and fail to descend into the scrotal sac |
front 5 deferential artery | back 5 arises from the vesicle artery (a branch of the internal iliac artery) and supplies the vas deferens and epididymis |
front 6 ejaculatory ducts | back 6 connect the seminal vesicle and the vas deferens to the urethra at the verumontanum |
front 7 epididymal cyst | back 7 cyst filled with clear, serous fluid located in the epididymis |
front 8 epididymis | back 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 |
front 9 epididymitis | back 9 inflammation of the epididymis |
front 10 hematocele | back 10 blood located between the visceral and parietal layers of the tunica vaginalis |
front 11 hydrocele | back 11 fluid formed between the visceral and parietal layers of the tunica vaginalis |
front 12 mediastinum testis | back 12 central linear structure formed by the convergence of multiple thin septations within the testicle; the septations are invaginations of the tunica albuginea |
front 13 pampiniform plexus | back 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 |
front 14 pudendal artery | back 14 the internal and external pudendal arteries partially supply the scrotal wall and epididymis and occasionally the lower pole of the testis |
front 15 pyocele | back 15 pus located between the visceral and parietal layers of the tunica vaginalis |
front 16 recurrent rami | back 16 terminal ends of the centripetal (intratesticular) arteries that curve backward toward the capsule |
front 17 rete testis | back 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 |
front 18 scrotum | back 18 sac containing the testes and epididymis |
front 19 seminal vesicles | back 19 reservoirs for sperm located posterior to the bladder |
front 20 septa testis | back 20 multiple septa formed from the tunica albuginea that course toward the mediastinum testis and separate the testicle into lobules |
front 21 spermatic cord | back 21 structure made up of vas deferens, testicular artery, cremasteric artery, and pampiniform plexus that suspends the testis in the scrotum |
front 22 spermatocele | back 22 cyst in the vas deferens containing sperm |
front 23 testicle | back 23 male gonad that produces hormones that induce masculine features and spermatozoa |
front 24 testicular artery | back 24 artery arising from the aorta just distal to each renal artery; it divides into two major branches, supplying the testis medially and laterally |
front 25 testicular vein | back 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 |
front 26 tunica albuginea | back 26 inner fibrous membrane surrounding the testicle |
front 27 tunica vaginalis | back 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 |
front 28 urethra | back 28 small membranous canal that extends from the bladder to the end of the penis |
front 29 varicocele | back 29 dilated veins in the pampiniform plexus caused by obstruction of the venous return from the testicle |
front 30 vas deferens | back 30 tube that connects the epididymis to the seminal vesicle |
front 31 verumontanum | back 31 junction of the ejaculatory ducts with the urethra |
