Autonomic Nervous System

The insides of our body, i.e. the gut or viscera is controlled by the autonomic nervous system.  It acts as a carrier transferring information regarding the inside of our body to CNS and then controls all the action taking place in the internal organs, this includes the heart, the gut, the secretion of norepinephrine (noradrenaline) and epinephrine (Adrenaline) from the medulla of the adrenal gland. The autonomic nervous system helps to play an essential role when it comes to keeping our temperature, blood sugar, salt concentration, carbon dioxide level, and so on in proper balance. It helps to maintain a condition that is known as homeostasis. A major part is played by the autonomic nervous system in expression and emotional experience. When we get emotionally excited our body ends up showing several changes, this includes the increase in heart beat and blood pressure, the feeling of ‘butterflies’ in the stomach, and dry mouth. All of these body actions and more are controlled by autonomic nervous system.

Understanding Autonomic Nervous System –

By now you can understand that the autonomic nervous system is responsible for regulating several body processes all of which occurs autonomously that is without any effort from us. Any disorder can end up affecting anybody process or part. This is that part of our nervous system which supplies a majority of the internal organs that includes the blood vessels, intestine, stomach, kidneys, liver, genitals, bladder, pupils, heart, lungs, salivary, digestive glands, and sweat. It is divided into two parts – sympathetic and parasympathetic. Once the autonomic nervous system has received the information about the external environment and the body, it starts to respond by stimulating the body process.

What function does autonomic nervous system serve?

These are the list of internal body processes that the autonomic nervous system controls –

  1. Blood pressure
  2. Breathing and heart rates
  3. Body temperature
  4. Metabolism and thus it has an impact on the body weight.
  5. It maintains a balance between electrolytes and water.
  6. Production of body fluids – tears, saliva, and sweat
  7. Defecation
  8. Urination
  9. Sexual response

Several organs in our body is controlled either by the parasympathetic or sympathetic division. Sometimes both of these divisions might end up having opposite effects or different reactions on the organs. Did you know that the sympathetic division is responsible for increasing the blood pressure and parasympathetic division helps to decrease it? Both of these divisions work in tandem to ensure that our body is responding the right way to different situations.

The sympathetic division prepares our body for every emergency or stressful situation which is either to flight or fight. On the other hand, the parasympathetic division has a control over the ordinary situations. It conserves and restores. Both the divisions – sympathetic and parasympathetic is directly involved with every sexual activity, the same way the nervous system parts are. It transmits sensational rising from the skin and helps to control voluntary actions.

This is how crucial autonomic nervous system is and it maintains a wide range of body processes.
