inferior hypogastric plexusAbbreviation: IHP
A long, thin descending extension from the superior hypogastric plexus on the right and the left sides. The inferior hypogastric plexus, which feeds into the pelvic, middle rectal, vesical, prostatic, and uterovaginal plexuses, contains sympathetic axons from the superior hypogastric plexus and the lowest lumbar splanchnic nerves and parasympathetic axons from the pelvic splanchnic nerves. The inferior hypogastric plexus (or a portion of it) is sometimes called the hypogastric nerve or the pelvic plexus.
