It is fair to say that the nervous system is the master control unit inside your body. It has a huge responsibility for sending, receiving and processing nerve impluses throughout the body. For the facilitaion of this control unit there are sense organs that afford this information by means of sight, smell, hearing, taste, pressure and pain. There are nerves that are connected throughout the body to the brain which carry information by electrochemical signals called impluses. It is the aim of these impluses to travel from the brain and spinal cord to the nerves sited throughout the body.
The autonomic nervous system ensures that our unconscious breathing is carried out in a regular rate and pattern. Being part of the peripheral nervous system the brain stem or medulla is the centre where the nerve cells send simultaneous signals to the intercostal muscles (ribs & diaphragm) to contract and relax at regular intervals. The ANS controls the body's internal environment which also helps control the heart rate, blood pressure, digestion respiration.
