Sacral splanchnic nerves
sacral splanchnic nerves
branches from the sacral sympathetic trunk that pass to the inferior hypogastric plexus; part of the abdominopelvic (sympathetic) splanchnic nerves, but their specific function is unclear. They tend to be confused with the pelvic splanchnic nerves, which are much more significant structures.
Synonym: nervi splanchnici sacrales.
