Anxiety and Our Brains- Part 2: The Nervous System
Posted Oct 07 2009 10:01pm
I am finding a lot ofempowermentin learning all of this information. This morning I was really nervous about my busy scheduled day that I had planned and I could feel the anxiety rising. I took somedeep breathsand told myself that I am justsending out a lot of stressful messageswhen it doesn't have to be. So I kept telling myself that its going to be okay, that it isn't as stressful and scary as I think its going to be and its just my brain overreacting, and that really helped to calm me down!
The next few posts in this series will be dedicated to the different structures of the brain and how they relate to anxiety. Your brain has many structures within it that can work together in systems to get a task done. Lets start with the first one, the Nervous System.
As I quickly noted in Part 1 of Anxiety and Our Brains, neurotransmitters are messengers that are received in different parts of the brain, and where they are received affects the message. I love the example from the book. This concept is explained as the scenario of a person sending an email expressing their love for a coworker. If the message is sent to that co worker, he or she may be thrilled. However, if that same message is accidentally sent to the boss, that boss is going to be upset because he is worrying about what his employees are doing on company time. Same message, different receivers, different outcomes.
The nervous system as defined by Wikipedia, " The nervous system is a network of specialized cells that communicate information about an organism's surroundings and itself."
Or in other words, the nerves carry messages to and from your organs and then tell your brain how your body is doing.
It has nerves that get your organs going and nerves that calm down the activity in your organs. It encompasses all of the nerves that run through the body and connect to the spinal cord and the brain.
3 Major Divisions of Nerve Activity that are Related to Anxiety:
The Peripheral Nervous System (PNS)- It's main function is to connect the Central Nervous System to the brain and organs, however it also carries messages to and from the skin. For example, this is the system that makes you blush.
