relations of vas deferens (crosses) {4}
1-external iliac artery, vein
2-obturator nerve, artery, vein
3-obliterated umbilical artery
4-inferior vesical vessels
function of seminal vesicles
1-contains seminal fluid
2-contains fructose from sperm nutrition
sacculated pouch
5cm long
b/w base of bladder & rectum
seminal vesicle

b/w base of bladder & rectum
describe course of vas deferens in details (7)
1-begins as continuation of tail of epididymis
2-passes thru deep inguinal ring
3-hooks on internal epigastric vessels
4-runs backwards & downwards on pelvic side wall to reach base of bladder
5- descends medial to seminal vesicle
6-terminal part dilates into ampulla of vas
7-joins duct of seminal vesicle to form ejaculatory duct
position of vas deferens relative to seminal vesicles
MEDIAL!
ejaculatory duct is formed by union of
vas deferens & duct of seminal vesicle
