Roll over to label;Click to display pages, click the blinking end page to demonstrate ejaculatory duct page.

The ejaculatory ducts, which unite the duct of the seminal vesicle with the terminal part of the ductus deferens, enter the prostatic urethra at the seminal colliculus. The seminal colliculus is placed at the summit of the urethral crest, which has the two ejaculatory ducts (left and right) flanking its sides. The left and right grooves on the sides of the urethral crest are the prostatic sinuses.

Arteries
Artery of ductus deferens from the superior vesical artery. It anastomoses with testicular artery and therefore also supplies the epididymis and testis.

Veins
Tributaries of the vein of ductus deferens, which drains into the vesical plexus.

Nerves:

Inferior hypogastric plexus

bullet

Parasympathetic fibers from the pelvic splanchnic nerve (S2-4.

bullet

Sympathetic fibers have their preganglionic motor fibers from the roots T10-12, and L1-2 to relay in the aortic, superior or inferior mesenteric ganglia or on the sympathetic trunk.
