Aortic plexus
Aortic Plexus
The Aortic Plexus (pronunciation: ay-or-tik plek-sus) is a complex network of nerves located in the abdomen, surrounding the aorta. The term originates from the Greek words aorte meaning 'that which is hung up' and plexus meaning 'braid'.
Description
The Aortic Plexus is primarily composed of sympathetic nerve fibers and is responsible for supplying the abdominal viscera. It is divided into the celiac plexus, the superior mesenteric plexus, and the inferior mesenteric plexus.
Function
The Aortic Plexus plays a crucial role in the autonomic regulation of the organs in the abdomen. It carries sympathetic fibers that control the contraction and relaxation of the smooth muscles in the abdominal organs, and also carries sensory fibers that transmit pain and other sensations from these organs to the brain.
