When uncoiled, the tube is about the diameter of a quill, and varies in length from 10 to 15 cm.; it ends posteriorly in a cul-de-sac; its anterior extremity becomes constricted into a narrow straight duct called the excretory duct of seminal gland (or duct of the seminal vesicle), which joins with the corresponding ductus deferens to form the ejaculatory duct[WP]. ductus excretorius (vesicula seminalis) Wikipedia:Excretory_duct_of_seminal_gland excretory duct of seminal gland SCTID:279675008 FMA:19473 duct of male reproductive system seminal vesicle fluid
