Hypogastric plexus

Hypogastric Plexus

The Hypogastric Plexus is a complex network of nerves located in the pelvic region of the body. It plays a crucial role in the autonomic nervous system, specifically in the regulation of the pelvic organs.

Anatomy

The Hypogastric Plexus is situated in front of the last lumbar vertebra and the upper part of the sacrum. It is formed by the union of the parasympathetic fibers from the splanchnic nerves and the sympathetic fibers from the lumbar ganglia.

Function

The Hypogastric Plexus carries both sympathetic and parasympathetic fibers. The sympathetic fibers are responsible for inhibiting peristalsis and contracting the internal sphincters of the bladder and rectum. The parasympathetic fibers, on the other hand, stimulate peristalsis and relax the internal sphincters.

Clinical Significance

The Hypogastric Plexus is of clinical significance due to its role in various medical conditions. For instance, a Hypogastric Plexus Block is a procedure used to manage pelvic pain that does not respond to other treatments. This procedure involves injecting medication into the plexus to block the nerves from transmitting pain signals to the brain.
