Aorticorenal Ganglion
The aorticorenal ganglion is composed of the superior mesenteric, renal, and inferior mesenteric ganglia. This is distinct from the celiac ganglia. However, they are part of the preaortic ganglia. Sympathetic input to the gut comes from the sympathetic chain next to the thoracic vertebrae. The upper nerve supply arrives from cell bodies at the levels of T5–T9, leaves the sympathetic chain by the greater splanchnic nerve, and synapses in the celiac ganglion before proceeding onto the foregut. Below this the lesser splanchnic nerve arises from T10–T11, leaves the sympathetic chain and synapses at the aorticorenal ganglion before going onto also supply the kidney and upper ureter. Below this the least splanchnic nerve arises from T12 and leaves the sympathetic chain to synapse at the "renal plexus The renal plexus is a complex network of nerves formed by filaments from the celiac ganglia and plexus, aorticorenal ganglia, lower thoracic splanchnic nerves and first lumbar s ...

Sympathetic Trunk
The sympathetic trunks (sympathetic chain, gangliated cord) are a paired bundle of nerve fibers that run from the base of the skull to the coccyx. They are a major component of the sympathetic nervous system. Structure The sympathetic trunk lies just lateral to the vertebral bodies for the entire length of the vertebral column. It interacts with the anterior rami of spinal nerves by way of rami communicantes. The sympathetic trunk permits preganglionic fibers of the sympathetic nervous system to ascend to spinal levels superior to T1 and descend to spinal levels inferior to L2/3.Greenstein B., Greenstein A. (2002): Color atlas of neuroscience – Neuroanatomy and neurophysiology. Thieme, Stuttgart – New York, . The superior end of it is continued upward through the carotid canal into the skull, and forms a plexus on the internal carotid artery; the inferior part travels in front of the coccyx, where it converges with the other trunk at a structure known as the ganglion impa ...

Celiac Plexus
The celiac plexus, also known as the solar plexus because of its radiating nerve fibers, is a complex network of nerves located in the abdomen, near where the celiac trunk, superior mesenteric artery, and renal arteries branch from the abdominal aorta. It is behind the stomach and the omental bursa, and in front of the crura of the diaphragm, on the level of the first lumbar vertebra. The plexus is formed in part by the greater and lesser splanchnic nerves of both sides, and fibers from the anterior and posterior vagal trunks. The celiac plexus proper consists of the celiac ganglia with a network of interconnecting fibers. The aorticorenal ganglia are often considered to be part of the celiac ganglia, and thus, part of the plexus. Structure The celiac plexus includes a number of smaller plexuses: Other plexuses that are derived from the celiac plexus: Terminology The celiac plexus is often popularly referred to as the solar plexus.

Superior Hypogastric Plexus
The superior hypogastric plexus (in older texts, hypogastric plexus or presacral nerve) is a plexus of nerves situated on the vertebral bodies anterior to the bifurcation of the abdominal aorta. Structure From the plexus, sympathetic fibers are carried into the pelvis as two main trunks- the right and left hypogastric nerves- each lying medial to the internal iliac artery and its branches. The right and left hypogastric nerves continues as Inferior hypogastric plexus; these hypogastric nerves send sympathetic fibers to the ovarian and ureteric plexuses, which originate within the renal and abdominal aortic sympathetic plexuses. The superior hypogastric plexus receives contributions from the two lower lumbar splanchnic nerves (L3-L4), which are branches of the chain ganglia. They also contain parasympathetic fibers which arise from pelvic splanchnic nerve (S2-S4) and ascend from Inferior hypogastric plexus; it is more usual for these parasympathetic fibers to ascend to the left-han ...

Celiac Ganglion
The celiac ganglia or coeliac ganglia are two large irregularly shaped masses of nerve tissue in the upper abdomen. Part of the sympathetic subdivision of the autonomic nervous system (ANS), the two celiac ganglia are the largest ganglia in the ANS, and they innervate most of the digestive tract. They have the appearance of lymph glands and are placed on either side of the midline in front of the crura of the diaphragm, close to the suprarenal glands (also called adrenal glands). The ganglion on the right side is placed behind the inferior vena cava. They are sometimes referred to as the semilunar ganglia or the solar ganglia. Neurotransmission The celiac ganglion is part of the sympathetic prevertebral chain possessing a great variety of specific receptors and neurotransmitters such as catecholamines, neuropeptides, and nitric oxide and constitutes a modulation center in the pathway of the afferent and efferent fibers between the central nervous system and the ovary.

Superior Mesenteric Ganglion
The superior mesenteric ganglion is a ganglion in the upper part of the superior mesenteric plexus. It lies close to the origin of the superior mesenteric artery. Structure The superior mesenteric ganglion is the synapsing point for one of the pre- and post-synaptic nerves of the sympathetic division of the autonomic nervous system. Specifically, contributions to the superior mesenteric ganglion arise from the lesser splanchnic nerve, which typically arises from the spinal nerve roots of T10 and T11. This nerve goes on to innervate the jejunum, the ileum, the ascending colon and the transverse colon. While the sympathetic input of the midgut is innervated by the sympathetic nerves of the thorax, parasympathetic innervation is done by the vagus nerve The vagus nerve, also known as the tenth cranial nerve, cranial nerve X, or simply CN X, is a cranial nerve that interfaces with the parasympathetic control of the heart, lungs, and digestive tract. It comprises two nervesâ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Renal Ganglia
The renal plexus is a complex network of nerves formed by filaments from the celiac ganglia and plexus, aorticorenal ganglia, lower thoracic splanchnic nerves and first lumbar splanchnic nerve and aortic plexus. The nerves from these sources, fifteen or twenty in number, have a few ganglia developed upon them. It enters the kidneys on arterial branches to supply the vessels, Renal glomerulus, and tubules with branches to the ureteric plexus. Some filaments are distributed to the spermatic plexus and, on the right side, to the inferior vena cava. The ovarian plexus arises from the renal plexus, and is one of two sympathetic supplies distributed to the ovary and fundus of the uterus The uterus (from Latin ''uterus'', plural ''uteri'') or womb () is the organ in the reproductive system of most female mammals, including humans that accommodates the embryonic and fetal development of one or more embryos until birth.
