The Celiac Plexus is a network of nerves located in the abdomen, near the aorta and the diaphragm. It plays a crucial role in the autonomic nervous system, primarily controlling the functions of the abdominal organs, including the stomach, liver, pancreas, and intestines. This plexus is responsible for transmitting signals that regulate digestion and blood flow to these organs. It is also involved in pain sensation from the abdominal area. Medical procedures, such as a celiac plexus block, can be performed to alleviate pain related to certain conditions affecting the abdomen.
