Differences between central nervous system and peripheral nervous system:
The central nervous system is made up of the brain and spinal cord.
The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.
Simply, it is the separation of the nervous system into it’s two main parts. Each of these parts can be broken down into more specific parts.
Brain and body are connected, they communicate. Most of the sensors take information from your body to the brain. For the brain to act, commands from the brain are transmitted to the body. If there were no peripheral nerves, you will have no information from the skin, muscles, pain receptors, etcetera transmitted to the brain.
Components of nervous system:
The peripheral nervous system can be divided into two components:
-the somatic nervous system: controls voluntary actions such as walking.
-the autonomic nervous system: is responsible for the control of vital functions such as heart beat and breathing. This one has also two parts:
--> Parasympathetic division (rest and digest)
--> Sympathetic division (active and alert)
