Ganglion Renal-Aortic

The renal-aortic ganglion (g. renale aorticum) is a small ganglion located between the aorta and the kidney. It is part of the sympathetic nervous system and plays an important role in regulating blood pressure and kidney function.

The renal aortic ganglion receives nerve fibers from the sympathetic nerves that exit the spinal cord and pass through the thoracic and lumbar parts of the spinal column. It also receives incoming nerve impulses from receptors located in the walls of the aorta and renal arteries.

This ganglion plays an important role in regulating blood pressure. When pressure in the arteries increases, the renal aortic ganglion receives signals from receptors in the wall of the aorta and renal arteries, which leads to a decrease in the activity of the sympathetic nervous system and dilation of blood vessels in the kidneys. This reduces resistance to blood flow and lowers blood pressure.

In addition, the renal aortic ganglion plays an important role in regulating kidney function. It controls the secretion of renin, a hormone that is involved in the regulation of blood pressure and blood volume. With increased pressure in the arteries, the renal aortic ganglion reduces the release of renin, which leads to a decrease in circulating blood volume and a decrease in blood pressure.

Overall, the renal aortic ganglion is an important element in the regulation of blood pressure and kidney function. Studying it and understanding its role in the body can help develop new treatments for hypertension and other diseases associated with impaired renal and cardiovascular function.
