The celiac ganglia are two large irregularly shaped masses of nerve tissue in the upper abdomen. The crura of the diaphragm (singular=crus are tendinous structures that extend downward from the diaphragm to attach to the Vertebral column. For other types of diaphragm see Diaphragm. In the Anatomy of Mammals the thoracic diaphragm is a sheet of Muscle The lumbar arteries are in series with the intercostals. They are usually four in number on either side and arise from the back of the Aorta, opposite the bodies Thoracic splanchnic nerves are Splanchnic nerves that arise from the Sympathetic trunk in the Thorax and travel inferiorly to provide sympathetic innervation The celiac artery, also known as the celiac trunk and also spelled as coeliac, is the first major branch of the Abdominal aorta and branches from the aorta The celiac plexus (also known as the solar plexus) is a complex network of nerves (a Plexus) located in the abdomen Thoracic splanchnic nerves are Splanchnic nerves that arise from the Sympathetic trunk in the Thorax and travel inferiorly to provide sympathetic innervation In Mammals the adrenal glands (also known as suprarenal glands) are the triangle-shaped Endocrine glands that sit on top of the Kidneys their In Human anatomy, the stomach is a J-shaped hollow muscular organ of the Gastrointestinal tract involved in the second phase of Digestion, following The liver is a vital organ in the human body and is present in Vertebrates and some other animals The caudate lobe ( posterior hepatic segment I, Spigelian lobe) is situated upon the postero-inferior surface of the liver on the Left lobe of the liver, The kidneys are complicated organs that have numerous biological roles Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome.

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). A Lymph node ( lɪmf noʊd is an organ consisting of many types of cells and is a part of the Lymphatic system. For the Stilt-legged fly Subgenus of Metopochetus, see Crus. For other types of diaphragm see Diaphragm. In the Anatomy of Mammals the thoracic diaphragm is a sheet of Muscle In Mammals the adrenal glands (also known as suprarenal glands) are the triangle-shaped Endocrine glands that sit on top of the Kidneys their The ganglion on the right side is placed behind the inferior vena cava. The inferior vena cava (or IVC is the large Vein that carries de-oxygenated Blood from the lower half of the body into the Heart.
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. A neuropeptide is any of the variety of Peptides found in Neural tissue; e
The main preganglion neurotransmitter of the celiac ganglion is acetylcholine, yet the celiac ganglion-mesenteric complex also contain α and β adrenergic receptors and is innervated by fibers of adrenergic nature that come from other preaortic ganglia. The Chemical compound acetylcholine (often abbreviated ACh) is a Neurotransmitter in both the Peripheral nervous system (PNS and Central Prevertebral ganglia (or collateral ganglia, or preaortic ganglia) are Sympathetic ganglia which lie between the Sympathetic chain and the
Path
The upper part of each ganglion is joined by the greater splanchnic nerve, while the lower part, which is segmented off and named the aorticorenal ganglion, receives the lesser splanchnic nerve and gives off the greater part of the renal plexus. Thoracic splanchnic nerves are Splanchnic nerves that arise from the Sympathetic trunk in the Thorax and travel inferiorly to provide sympathetic innervation Thoracic splanchnic nerves are Splanchnic nerves that arise from the Sympathetic trunk in the Thorax and travel inferiorly to provide sympathetic innervation The renal plexus is formed by filaments from the Celiac plexus, the Aorticorenal ganglion, and the Aortic plexus.
Innervation
These ganglion contain neurons whose unmyelinated postganglionic axons innervate the stomach, liver, gallbladder, spleen, kidney, small intestine, and the ascending and transverse colon. They directly innervate the ovarian theca and secondary interstitial cells and exert an indirect action on the luteal cells.
Links to Ovary
Modifications in the adrenergic activity of the celiac ganglion results in an altered capacity of the ovary of pregnant rats to produce progesterone, suggesting that the celiac ganglion-superior ovarian nerve-ovarian axis provides a direct link between the autonomic nervous system and the physiology of pregnancy. It has also been shown that modifications in the cholinergic input at the celiac ganglion also led, via the superior ovarian nerve, to modifications in ovarian steroidogenesis. Steroid metabolism is the complete set of Chemical reactions in organisms that produce modify and consume Steroids These Metabolic pathways include Most of the fibers of the superior ovarian nerve come from the postganglionic sympathetic neurons of the celiac ganglion.
