[ANAT] EPIDIDYMIS, SPERMATIC CORD, PENIS Flashcards
reservoir for sperms
epididymis
head of epididymis is connected to testis via
vas efferentia
lenght of epididymis
6 meters
epididymis shape
comma shaped
epididymis site
close to upper end & posterior border of testis
body of epididymis is formed of
a single coiled duct
body of epididymis site
posterior border of testis
tail of epididymis is continuous with
vas deferens
epididymis arterial supply
1-testicular artery (br of abdominal aorta)
2-artery of vas (br of superior vesical artery)
3- cremasteric artery (br of inferior epigastric artery)
epididymis venous drainage
1-right testicular vein (–>IVC)
2-left testicular vein (–>left renal vein)
epididymis lymphatic drainage
pre-aortic LNs
lateral aortic LNs
epididymis nerve supply
sympathetic fibers accompanying testicular artery
(& connected to T10)
content of spermatic cord (12)
3 arteries: (1) testicular artery
(2) cremasteric artery
(3) artery of vas
3V’s : (4) Vas deferens
(5) Venous plexus
(6) Vestige of processus vaginalis
3 nerves: (7) genital br of genitofemoral nerve
(8) sympathetic plexus around testicular artery
(9) sympathetic plex around artery of vas
3L’s: (10) Loose areolar tissue
(11) Lymphatics of testis
(12) Lymphatics of epididymis & vas
function of vas deferens
transport spermatozoa from epididymis to ejaculatory duct
thick walled muscular duct with narrow lumen
vas deferens
covering of spermatic cord (3)
1- external spermatic fascia
2-cremasteric muscle & fascia
3-internal spermatic fascia
external spermatic fascia arises from
external oblique aponeurosis
internal spermatic fascia arises from
fascia transversalis
cremasteric muscle & fascia arise from
internal oblique muscle
