The solar plexus, also known as the celiac plexus, is a complex network of nerves located in the abdomen behind the stomach. It is part of the autonomic nervous system, which regulates unconscious bodily functions such as digestion, circulation, and respiration. The solar plexus is made up of nerve fibers from the sympathetic and parasympathetic nervous systems, which work together to maintain the body's internal balance. The solar plexus is responsible for regulating the function of several organs, including the stomach, liver, pancreas, and intestines. It is also involved in the sensation of emotions, such as anxiety and fear, due to its connections with the adrenal glands, which produce hormones in response to stress.
