Structure The inferior hypogastric plexus is a paired structure, with each situated on the side of the rectum in the male, and at the sides of the rectum and vagina in the female. The posterior aspect of the rectum exposed by removing the lower part of the sacrum and the coccyx. ...
The shield and spear of the Roman God Mars are often used to represent the male sex In heterogamous species, male is the sex of an organism, or of a part of an organism, which typically produces smaller, mobile gametes (spermatozoa) that are able to fertilise female gametes (ova). ...

They are formed on either side by a continuation of the hypogastric plexus, in the form of the hypogastric nerve. They are also contributed to by sacral splanchnic nerves, which emerge from the sympathetic trunk. The pelvic splanchnic nerves (from the second, third, and fourth sacral nerves) also contribute, providing parasympathetic efferent fibers to the plexus. The sympathetic trunk (sympathetic chain, gangliated cord) is a bundle of nerve fibers that runs from the base of the skull to the coccyx. ...
The Sacral Nerves—The posterior divisions of the sacral nerves (rami posteriores) are small, and diminish in size from above downward; they emerge, except the last, through the posterior sacral foramina. ...
At the points of junction of these nerves small ganglia are found. From these plexuses numerous branches are distributed to the viscera of the pelvis. The pelvis (pl. ...
They accompany the branches of the internal iliac artery. The Internal iliac artery, formerly known as the hypogastric artery, supplies the walls and viscera of the pelvis, the buttock, the reproductive organs, and the medial compartment of the thigh. ...
