Scientists have just revealed a new aspect of the human heart that is truly extraordinary. The heart is capable of self-protection, and its little network of nerve cells is the major mechanism for that defense. Also, scientists have confirmed that this little brain of the heart helps to protect the body in stressful situations much more than what they had previously thought. The new study confirms further that the heart is far from being just a pump but is also an integral part of the body’s defense against stress. The heart is composed of thousands of specially adapted neurons that make up its own internal nervous system. This complicated network is responsible for continuous communication between the heart lungs blood vessels and other organs in a bid to regulate the heart beat, blood flow, and general cardiovascular functions. Now, scientists are confident that the heart can not just react on the signals coming from outside but may also process information and act upon it. It is the capability to respond to the change before that the signal reaches the brain that makes the heart so remarkable.
Latest studies show that this mini brain in the heart allows efficient heart function during times of heightened stress. The heart is not totally dependent on the central nervous system’s messages; rather, the heart’s own neurons can affect how the organ responds to things such as intense exercise, emotional upheaval or a jump in blood pressure. The researchers say they found out that these tiny neurons of the heart do not act alone but work in a team. Their group efforts give the heart the ability to adjust so that vital organs continue getting the blood full of oxygen even when the body’s response to stress has reached an intense level.
These results may lead researchers to see cardiovascular health in a new light. It was generally thought for a good part of the past that signals traveled only one way – from the brain to the heart. But there seems to be two-way communication after all with the heart playing its own small part through contributing to regulating the body’s overall stress response. Stress is something that has become a global issue with its effect manifesting itself through an increased incidence of high blood pressure, heart disease, stroke and other long-standing conditions.
Heart health will be at the forefront as new cardiovascular drugs and better prevention methods will come from understanding how the heart naturally protects oneself in stress situations. That, in turn, could provide the keys to unlocking such problems and the heart’s health generally. Not only for controlling the heartbeat but the nervous system of the heart also aids in the body’s overall stress management. These nerve cells work to organize the heartbeat by responding locally to signals. Any disturbance of that network might cause heart rhythm problems; Because of this the investigation is very relevant to the research on cardiac diseases.
The development of techniques such as more accurate imaging of the heart and a better understanding of how brain nerve cells work has led to discoveries about the heart’s nervous system. Through the use of various scientific instruments, researchers are now able not only to see single nerve cells of the heart but also to determine how such neurons interact. With this kind of technology at hand, the research community is gaining a more complete vision of the heart’s internal communication system. Fellow researchers also believe that the heart’s own internal network may work as a new focus area for the development of medicines. The idea of treating only the symptoms may be over. On the contrary, the treatments could also target improving the communication among the heart’s nerve cells to restore their normal function.
