Cardiac Plexus - English Definition & Meaning

Definition

The cardiac plexus is a network of nerves located near the base of the heart. It's responsible for regulating heart rate, contractility, and blood vessel tone. Think of it as the heart's control center, receiving input from both the sympathetic and parasympathetic nervous systems. The sympathetic system speeds up the heart, while the parasympathetic system slows it down. This intricate balance ensures the heart adapts to the body's changing needs. The cardiac plexus is essential for maintaining cardiovascular function.

Etymology

Together, they describe the interwoven network of nerves surrounding the heart. Early anatomical investigations identified this nerve network, gradually revealing its functional significance.
