The nervous system consists of the brain, spinal cord, nerves and sense organs. This system is responsible for sending, receiving, and interpreting information from all parts of the body. The nervous system monitors and coordinates internal body functions and responds to changes in the external environment. Broadly speaking, our brains allow us to think and feel, and to choose to respond to information that is received from our senses. The brain is a highly complex organ which is responsible for multitude of functions. It is involved in mental functions such as our thoughts, memory, concentration and our ability to understand languages, as well allowing us to feel emotions like joy, anger, sadness, hope and love. It also controls many vital involuntary processes like breathing, blood pressure and heart function, as well as our thirst, hunger and sexual function. The nerve cells found throughout our bodies use electro-chemical signals called nerve impulses to communicate with one another and with other parts of the body. It is very important for our overall state of wellbeing that we avoid overstressing our nervous systems and that we keep them well nourished and supported.
