Renal nerves refer to the nerves that innervate the kidneys and play a crucial role in regulating renal function. These nerves help control various physiological processes in the kidneys, such as blood flow, renal blood pressure, and electrolyte balance. Dysfunction or overactivity of renal nerves can lead to conditions such as hypertension and kidney disease. Research in this area focuses on understanding the role of renal nerves in kidney function and developing new therapeutic approaches for conditions related to renal nerve dysfunction.
