Dissection of male pelvis from a lateral approach
Pelvic plexus of right side, medial view
The pelvic plexus on the right side of the specimen has been freed of connective tissue. The superior hypogastric plexus is visible entering from above. Extending to the pelvic plexus from the sacral part of the sympathetic trunk is one sacral splanchnic nerve (18). The pelvic splanchnic nerves (19, 20) from the 3rd and 4th sacral nerves carry parasympathetic fibers to the plexus. Branches of the pelvic plexus to the ureter, ductus deferens, bladder, prostate and rectum are visible.
