Which of the following aeries gives blood supply to the ductus deferens?
Correct Answer: Superior vescial aery
Description: D i.e. Superior vesicle aery Vas (ductus) deferens is 45 cm long muscular tube which conveys sperms from epidytlimis to ejaculatory duct. It receives blood from its own aery (i.e., aery to ductus deferens) which usually arises from superior vesical aeryQ (but may occasionally arise from inferior vesical aery). Aery to ductus deferens anastomose with testicular aery to supply epididymis and testis.- Testicular aery also supplies perirenal fat, ureter, & iliac lymph node (in abdomen), and cremaster (in inguinal canal). The testicular aery represent peisistent lateral splanchnic aoic branches.Testis is mainly supplied by testicular aeryQ (an anterior branch of aoa). It also recieves blood from the cremasteric branch of inferior epigastric aery and from aery to vas (ductus) deferens (branch of superior vesicle aery)Q. That's why ligation of testicular aery high in abdomen usually leave testis unharmed, whereas interruption in the region of spermatic cord may interefere with all vessels & cause infarction.- In treating varicocele, both testicular aery & vein are ligated quite high up, which provides the advantage of ligating venae comitantes of aery. If left open these venae comitantes can lead to recurrence because of their anastomoses with internal spermatic veins
