25
artery arising from the aorta just distal to each renal artery; it divides into two major branches, supplying the testis medially and laterally

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

junction of the ejaculatory ducts with the urethra
verumontanum
33
The testes are symmetric, oval-shaped glands residing in the \_\_\_\_\_\_
scrotum
34
The seminiferous tubules converge at the apex of each lobule and anastomose to form the \_\_\_\_\_\_\_\_in the mediastinum.
rete testis
35
The largest part of the epididymis is the \_\_\_\_\_\_, measuring 6 to 15 mm in width.

tunica albuginea
38
The _________ supports the ducts coursing within the testis.

increased
50
Hydroceles are found around the ______ aspect of the testis.
anterolateral
51
\_\_\_\_\_\_\_\_ of the spermatic cord occurs as a result of abnormal mobility of the testis within the scrotum.
torsion
52
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.
Bell Clapper

\_\_\_\_\_\_\_\_ are usually caused nu incompetent venous valves within the spermatic vein.
varicoceles
57
Omental hernias appear ________ because of the omental fat
echogenic
58
A(n) ________ contains serous fluid and is the most common cause of painless scrotal swelling.
hydroceles
59
