The celiac plexus is a dense network of nerves located in the upper abdomen, behind the stomach and near the aorta. It is sometimes called the “solar plexus” and serves as a major communication hub between the brain and several abdominal organs. These include the stomach, liver, pancreas, spleen, kidneys, and parts of the intestines. Because it connects to so many organs, it plays an important role in transmitting sensory and autonomic signals throughout the upper digestive system.
This nerve network helps regulate involuntary functions such as digestion, blood flow, and organ activity in the abdomen. When signals pass through this area, they can influence sensations like fullness, discomfort, or visceral pain originating from internal organs. Because of its wide range of connections, the celiac plexus is a key pathway for communication between the central nervous system and multiple abdominal structures, making it an important part of how the body coordinates internal organ function.
