The celiac ganglia or coeliac ganglia are two large irregularly shaped masses of

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.
The main preganglion neurotransmitter of the celiac ganglion is

The upper part of each ganglion is joined by the
Innervation
These ganglia contain neurons whose 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. Most of the fibers of the superior ovarian nerve come from the postganglionic sympathetic neurons of the celiac ganglion.
