What's in the Hypogastric region?
The hypogastric region (below the stomach) contains the organs around the pubic bone. These include bladder, part of the sigmoid colon, the anus, and many organs of the reproductive system, such as the uterus and ovaries in females and the prostate in males.
What is the root of Hypogastric?
The hypogastric nerve arises from the ventral nerve roots of T12 to L3 and supplies sympathetic nerve innervation. … The parasympathetic innervation (nervi erigentes) arises from the S2 to S4 ventral nerve roots and is found on the pelvic sidewall.
What is the Hypogastric region used for?
The hypogastric artery provides blood flow to several areas, including your: Pelvic wall. Pelvic viscera. PerineumWhat is the Hypogastric plexus?
The hypogastric plexus is a collection of nerves that is located in front of the fifth lumbar and first sacral vertebral bodies. This means that the plexus is located near the lower part of your abdomen in the upper front of your pelvis.
What does the superior hypogastric plexus do?
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.
What region is medial?
Medial means toward the middle or center. It is the opposite of lateral. The term is used to describe general positions of body parts. For example, the chest is medial to the arm.
What is the superior hypogastric plexus made of?
The superior hypogastric plexus is made up of nerve fibers extending inferiorly from the paravertebral sympathetic chain, joining together opposite the aortic bifurcation, anterior to the fourth and fifth lumbar vertebrae.What does the superior hypogastric plexus innervate?
Superior Hypogastric Plexus Injury The superior hypogastric plexus is situated in the bifurcation of the aorta on the fifth lumbar vertebral body and the sacrum. This sympathetic plexus innervates the smooth muscles of the seminal vesicle, which contracts as the bladder neck closes during ejaculation.

Article first time published onWhere is the Hypogastric located?
The hypogastrium (also called the hypogastric region or suprapubic region) is a region of the abdomen located below the umbilical region. The pubis bone constitutes its lower limit. The roots of the word hypogastrium mean “below the stomach”; the roots of suprapubic mean “above the pubic bone”.
Where does the Hypogastric nerve innervate?
Sympathetic innervation: Hypogastric nerve (L1–L4) via the caudal mesenteric ganglion. Postganglionic fibers innervate the bladder wall (β2 receptors) and proximal urethra (α1 with some α2 receptors). Parasympathetic innervation: The pelvic nerve (sacral segments) innervates the detrusor smooth muscle.
How do you say hypochondriac?
adjective Also hy·po·chon·dri·a·cal [hahy-poh-kuhn-drahy-uh-kuhl] /ˌhaɪ poʊ kənˈdraɪ ə kəl/ .
Where is 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.
What is the superior and inferior hypogastric plexus?
Inferior hypogastric plexusFMA6643Anatomical terms of neuroanatomy
Is the superior hypogastric plexus sympathetic or parasympathetic?
Background: The superior hypogastric plexus (SHP) is an autonomic plexus, located ventrally to the abdominal aorta and its bifurcation, innervating pelvic viscera. It is classically described as being composed of merely sympathetic fibres.
Is the hypogastric region is directly superior to the umbilical region?
The hypogastric region is directly superior to the umbilical region. The maintenance of boundaries between the internal organs of the body and the outside world is achieved by the endocrine system. The endocrine system is the fast-acting body control system.
What is lateral to the hypogastric region?
lateral to the hypogastric region (iliac=superior part of the hip bone). region contains the cecum & appendix. left iliac inguinal region. lateral to the hypogastric region (iliac=superior part of the hip bone).
Which of the following are regions of the abdominopelvic area?
- Umbilical region– center-most region (belly button)
- Epigastric region– superior to the umbilical region (above belly)
- Hypogastric region– inferior to the umbilical region (pubic area)
- Right iliac (inguinal region)-located lateral to the hypogastric region.
How superior hypogastric plexus is formed?
The SHP is formed by the bilateral lowest lumbar splanchnic nerves (LSNs) below the aortic bifurcation. The SHP is located anterior to left common iliac artery (CIA), the left common iliac vein, and the fifth lumbar vertebral body; B. The SHP is formed above the aortic bifurcation.
Is the inferior hypogastric plexus sympathetic or parasympathetic?
The inferior hypogastric plexus is a paired structure containing both parasympathetic nerves and sympathetic nerves arising from the inferior hypogastric plexus (Rob, Halaska, & Robova, 2010).
What muscles do the sacral plexus innervate?

What is the sympathetic plexus?
An autonomic plexus composed of sympathetic axons. Large sympathetic plexuses surround the midline (prevertebral) sympathetic ganglia, which are found near major midline arteries such as the celiac trunk. See also: plexus.
Which type of nerve fibers are carried through the superior hypogastric plexus?
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 superior mesenteric plexus supply?
It surrounds the superior mesenteric artery, accompanies it into the mesentery, and divides into a number of secondary plexuses, which are distributed to all the parts supplied by the artery, viz., pancreatic branches to the pancreas; intestinal branches to the small intestine; and ileocolic, right colic, and middle …
What does the Hypogastric Plexus control?
The inferior hypogastric plexus, the hub of all autonomic control within the pelvis, is a paired meshwork of nerves located on either side of the rectum lying medial to the internal iliac vessels. … The superior hypogastric plexus contains no parasympathetic fibers, so it is a purely sympathetic plexus.
What are Nervi Erigentes?
Pelvic splanchnic nerves or nervi erigentes are splanchnic nerves that arise from sacral spinal nerves S2, S3, S4 to provide parasympathetic innervation to the organs of the pelvic cavity.
What do sacral splanchnic nerves innervate?
The sacral splanchnic nerve provides both motor and sensory innervation to the posterior thigh, part of the pelvis, and the majority of the lower leg and foot.
What does the inferior Hypogastric ganglion innervate?
The inferior hypogastric plexus fibers innervate the smooth muscle fibers of the visceral portion of the levator ani muscle.
Is pelvic nerve sympathetic or parasympathetic?
The pelvic splanchnic nerves, also known as nervi erigentes, are preganglionic (presynaptic) parasympathetic nerve fibers that arise from the S2, S3 and S4 nerve roots of the sacral plexus. These nerves form the parasympathetic portion of the autonomic nervous system in the pelvis.
Where do sympathetic and parasympathetic efferents go to from the inferior hypogastric plexus?
The inferior hypogastric plexuses in humans contains numerous small ganglia containing nerve cell bodies of parasympathetic neurons to the rectum and anal canal, mixed with sympathetic fibers arriving via the hypogastric nerves.
