The aorticorenal ganglion is a cluster of nerve cells located near the aorta and the renal arteries. It is part of the autonomic nervous system, specifically the sympathetic division, and plays a role in regulating blood flow to the kidneys and other abdominal organs. This ganglion receives input from the celiac ganglion and sends fibers to the kidneys and surrounding structures. It helps control functions such as blood pressure and urine production by influencing the activity of the renal arteries and other related blood vessels.
