Celiac plexus
Celiac Plexus
The Celiac Plexus (pronounced: /ˈsiːliæk ˈpleksəs/), also known as the solar plexus, is a complex network of nerves located in the abdomen, near where the celiac trunk, superior mesenteric artery, and renal arteries branch from the abdominal aorta. It is behind the stomach and the omental bursa, and in front of the crura of the diaphragm, near the level of the first lumbar vertebra.
Etymology
The term "Celiac" is derived from the Greek word koiliakos, meaning "abdominal", and "Plexus" is derived from the Latin word plexus, meaning "braid" or "network". The term "solar" is used because of the plexus's radiating pattern, resembling the sun.
Function
The Celiac Plexus is primarily responsible for innervating the abdominal viscera. It plays a crucial role in the autonomic regulation of the internal organs, including the stomach, liver, spleen, kidneys, intestines, and adrenal glands.
