The average adult human brain contains 86 BILLION NEURONS; almost as many stars as there are in the Milky Way galaxy!
The nervous system is the master control system of your body. Every action, thought, and feeling is processed by your nervous system; therefore, making it the most important system in your body! The nervous system continually monitors the changes in your internal and external environments to determine your body’s best response or course of action. Your nervous system is always at work monitoring and regulating your body functions for optimal health.
If you lined up all the nerve cells in your body side by side, the total length would MEASURE OVER 500 MILES!
