Flashcards in Ch. 23 Deck (65)
Connect the seminal vesicle and the vas deferens to the urethra at the verumontanum
Reservoirs for sperm located posterior to the bladder
Plexus of veins in the spermatic cord that drain into the right and left testicular veins
Junction of the ejaculatory ducts with the urethra
Male gland that produces hormones that induce masculine features and spermatozoa
An extension of the internal oblique muscle that descends to the testis with the spermatic cord
Membrane consisting of a viseral layer and a parietal layer lining the inner wall of the scrotum
Partially supply the scrotal wall and epididymis and occasionally the lower pole of the testis
Tube that connects the epididymis to the seminal vesicle
Anatomic structure formed by the network of the ducts leaving the mediastinum testis that combine into a single, convoluted epididymal tubule
Artery arising from the aorta just distal to each renal artery
Central linear structure formed by the convergence of multiple, thin septations within the testicle, which are invaginations of the tunica albuginea
Small membranous canal that extends from the bladder to the end of the penis
Multiple septa formed from the tunica albuginea that course toward the mediastinum testis and separate the testicle into lobules
Inner fibrous membrane surrounding the testicle
Structure made up of vas deferens, testicular artery, cremasteric artery, and pampiniform plexus that suspends the testis in the scrotum
Sac containing the testes and epididymis
Small artery arising from the inferior epigastric artery, which supplies the peritesticular tissue, including the cremasteric muscle
Formed by pampiniform plexus.
Arises from the vesicle artery and supplies the vas deferens and epididymis
Terminal intratesticular arteries arising from the capsular arteries
Terminal ends of the centripetal arteries that curve backward toward the capsule
Dilated veins in the pampiniform plexus caused by obstruction of the venous return from the testicle
Cyst filled with clear, serous fluid located in the epididymis
Fluid formed between the visceral and parietal layers of the tunica vaginalis
Cyst in the vas deferens containing sperm
Inflammation of the epididymis
Testicles remain with the abdomen or groin and fail to descend into the scrotal sac
Pus located between the visceral and parietal layers of the tunica vaginalis
Network of the channels formed by the convergence of the straight seminiferous tubules in the mediastinum testis
Blood located between the visceral and parietal layers of the tunica vaginalis
The testes are symmetric, oval-shaped glands residing in the ______________.
The seminiferous tubules converge at the apex of each lobule and anastomose to form the _____________ in the mediastinum.
The largest part of the epididymis is the _____________, measuring 6 to 15 mm in width.
The ductus epididymis becomes the _____________ and continues in the spermatic cord.
The testis is completely covered by a dense, fibrous tissue termed the _______________.
The ____________ supports the ducts coursing within the testis.
The space between the layers of the tunica vaginalis is where _______________ can form.
The __________ is a continuation of the ductus _____________.
vas deferens; epididymis
The vas deferens dilates at the terminal portion near ____________.
Right and left testicular arteries arise from the ____________ just below the level of the renal arteries.
Venous drainage of the scrotum occurs through the veins of the ________________ plexus.
Power Doppler is often used as a way to quickly get to a sensitive setting that will demonstrate ___________ flow.
The most important goal of the ultrasound examination in testicular trauma is to determine if _________ has occurred.
An acute hematocele is ___________ with numerous, highly visible echoes that can be seen to float or move in real time.
The most common cause of acute scrotal pain in adults is ______________ infection of the epididymis and testis.
The normal epididymis shows ________ flow with color doppler.
With epididymitis, Doppler waveforms demonstrate _____________ velocities in both systole and diastole. A low resistance waveform pattern is present.
Hydroceles are found around the _____________ aspect of the testis.
______________ of the spermatic cord occurs as a result of abnormal mobility of the testis within the scrotum.
The ____________ anomaly occurs when the tunica vaginalis completely surrounds the testis, epididymis, and distal spermatic cord, allowing them to move and rotate freely within the scrotum.
Torsion is the most common cause of acute scrotal pain in _______________.
A(n) ______________ of perfusion in the symptomatic testis with normal perfusion demonstrated in the asymptomatic side is considered to be diagnostic of torsion.
Extratesticular cysts are found in the tunica ___________ or epididymis.
_______________ are usually caused by incompetent venous valves within the spermatic cord.
Omental hernias appear _____________ because of omental fat.
A(n) ____________ contains serous fluid and is the most common cause of painless scrotal swelling.
Testicular cancer occurs most frequently between the ages of ______________ years.
20 to 34
Patients with _____________ testes are 2.5 to 8 times more likely to develop cancer.
These masses called ______________ are usually benign, whereas _______________ masses are more likely to be malignant.
The term _______________ describes a condition in which the testis has not descended into the scrotum and cannot be brought into the scrotum with external manipulation.
undescended testis, cryptorchidism
What anatomic structure does this arrow point to?
Identify the abnormality in these images of the testes.
dilation of the rete testis
What is the arrow pointing to?
Pointing to the stalk connecting the cyst to the epididymal head.
