What is the superior hypogastric plexus?
The superior hypogastric plexus is a complex web of neurons and fibers responsible for transmitting subconscious sensation and signals to and from the pelvic region. Once chronic pain develops in the pelvis, this plexus becomes a main source of sending unwanted pain signals to the brain.
Where is the superior hypogastric plexus?
Your superior hypogastric plexus sits in front of the spine in the lower part of your back. Nerves from several parts of the lower abdomen and pelvis pass through this plexus. That includes nerves from the following organs: Bladder or urethra.
What is the superior and inferior hypogastric plexus?
The inferior hypogastric plexus is a paired structure, meaning there is one on the left and the right side of the body. These are located on either side of the rectum in males, and at the sides of the rectum and vagina in females….

Where does superior hypogastric plexus come from?
This plexus (sometimes referred to as the presacral nerve) is formed by the confluence of the lumbar sympathetic chains and branches of the aortic plexus that contains fibers that have traversed the celiac and inferior mesenteric plexuses.
What contributes to the superior hypogastric plexus?
The superior hypogastric plexus receives contributions from the two lower lumbar splanchnic nerves (L3-L4), which are branches of the chain ganglia.
Is the superior hypogastric plexus sympathetic or parasympathetic?
The superior hypogastric plexus contains the sympathetic function for the urogenital system. Parasympathetic function for the urogenital system is supplied by the S 1-L4 nerve roots that contribute to the pelvic splenic nerves. Somatic function from Sl, S2, S3, and S4 is carried predominantly by the pudendal nerve.
What does the hypogastric plexus do?
It is found on the lower part of your abdomen in front of the pelvis. The hypogastric plexus is where the nerves for many of the internal organs of the pelvis are located. Usually, people who have pain in these organs take medications for pain relief.
What does the inferior hypogastric plexus do?
The inferior hypogastric plexus gives numerous pelvic branches which supply the pelvic viscera directly, or more commonly, indirectly by providing fibers for smaller plexuses located in the walls of the organs (e.g. middle rectal plexus, the prostatic plexus, and the uterovaginal plexus also known as Frankenhäuser …
What does hypogastric nerve do?
The hypogastric nerve sends signals via the sympathetic nervous system to block bladder contraction and contact the internal urethral sphincter.
Is hypogastric nerve sympathetic or parasympathetic?
The hypogastric nerve (not to be confused with the iliohypogastric nerve) is a continuation of the superior hypogastric plexus. It is a sympathetic nerve, carrying the inputs from the T12-L3 segments of the spinal cord.
What forms the hypogastric plexus?
The plexus is formed by branches from three main sources: the abdominal aortic plexus (sympathetic and parasympathetic), lumbar splanchnic nerves (sympathetic) and pelvic splanchnic nerves (parasympathetic), which ascend from the inferior hypogastric plexus via the right and left hypogastric nerves (Kraima et al 2015).
What does hypogastric plexus supply?
The inferior hypogastric plexus supplies the portion of the rectum and the distal portion of the ureter together with the urinary bladder.
