18. The nervous system

Hi there, in this blog I start explaining (very high level) how pressure points work neurologically.

To be able to understand why the body reacts in a certain way, it is important to understand how the nervous system works. This blog give you an extremely simplified view of an extremely complicated organism.

The nervous system exists of 3 parts:

  1. The Autonomic nervous system 
  2. The Central nervous system 
  3. The Peripheral nervous system
The Autonomic nervous system
This is the part of the nervous system in the brainstem that controls our internal organs; like breathing, hart rate, pupils, vain, digestion, etc.

The Central nervous system
This nervous system exists of the brain and the spinal cord. It is the red part in the picture. This part of the nervous system processes the stimuli.

The Peripheral nervous system
The peripheral nervous system contains nerves that go from the spinal cord into the body. In the picture, they are colored brown. This Peripheral nervous system connects our organs and body parts with our central nervous system.

The nerve highway

There are two ways a nerve carries the information from and to the brain:
1. Via the afferent nerve fiber (sensory fiber) - transports signals from the body towards the spinal cord. Information about what the body feels, like pain when you burn your hand or step on a little stone.
2. Via the efferent nerve fiber (motoric fiber) - transports signals from the brain and spinal cord to the body. Information like, you have to move your legs to walk or if the brain want to grab something.

In my next blog I will continue with the neurological explanation by writing about the fibers.
