Coeliac plexus reaches to most of the abdominal viscera. Where is Coeliac plexus located?
The celiac (solar) plexus is located in the epigastric region over the abdominal aoa. It comprises of diffuse network of nerve fibers and individual ganglia that lie over the anterolateral surface of the aoa at the T12/L1 veebral level. It is formed from vagal fibers reaching it the esophageal plexus, sympathetic fibers arising from celiac ganglia, and sympathetic fibers coursing down from the thoracic aoic plexus. It projects to most of the abdominal viscera, which it reaches by way of numerous subplexuses, including phrenic, hepatic, splenic, superior gastric, suprarenal, renal, spermatic or ovarian, abdominal aoic, and superior and inferior mesenteric plexuses.
