Hypogastric plexus
Hypogastric Plexus
The Hypogastric Plexus (pronounced: hi-po-gas-trik plek-sus) is a significant part of the autonomic nervous system that plays a crucial role in the regulation of pelvic organ function.
Etymology
The term "Hypogastric Plexus" is derived from the Greek words 'hypo' meaning 'under' and 'gaster' meaning 'stomach', referring to its location below the stomach. 'Plexus' is a Latin term meaning 'braid', referring to the network of nerves.
Function
The Hypogastric Plexus carries both sympathetic and parasympathetic fibers. It provides innervation to the pelvic viscera, including the bladder, rectum, and internal genital organs. It plays a significant role in controlling functions such as urination, defecation, and sexual response.
Anatomy
The Hypogastric Plexus is located in the pelvic region, anterior to the sacrum and posterior to the rectum. It is formed by the union of the superior hypogastric plexus and the inferior hypogastric plexus.
Related Terms
- Superior Hypogastric Plexus: The superior hypogastric plexus is a continuation of the aortic plexus, located above the hypogastric plexus.
- Inferior Hypogastric Plexus: The inferior hypogastric plexus is located below the hypogastric plexus and is formed by the union of the pelvic splanchnic nerves and the sacral splanchnic nerves.
- Autonomic Nervous System: The autonomic nervous system is a control system that acts largely unconsciously and regulates bodily functions, including the heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal.
