What Are The Main Parts Of The Human Nervous System?

The nervous system functions using electrical impulses that are sent to and from the brain so that the rest of the body can function. Most of the things our body does (and also the bodies of most mammals) are because of the two nervous systems we have in our bodies.

There are two nervous systems in our body, these are both interlinked and work together. The central nervous system is made up of your brain and spinal cord. This nervous system sends signals to parts of the body so that it can function. It looks after your somatic reactions which is where you co-ordinate external things such as moving away from moving cars and also looks after the things that you can not see such as keeping your heart and lungs breathing and enteric functions such as digestion in your stomach. This central nervous system also helps when dealing with influences such as stress and other sympathetic external strains.

The peripheral nervous system looks after everything else and sends signals to the brain where they are intercepted by the central nervous system. For this reason, the peripheral nervous system is seen as the secondary nervous system. It looks after the functioning of the body when external influences need to be registered by the central nervous system. It carries impulses to the brain after you touch something and tells your brain whether something is hot or cold or even a danger. The central nervous system will then pull your hand away from it if it is a danger.

The glial cells surrounding the neurons carry the signals that go to the forbrain to be processed. These are then sent by the forbrain to the midbrain or hindbrain. The midbrain is used when the central nervous system steps into place to react and the hindbrain is passes on signals to the central nervous system for functions such as digestion or breathing.

The brain, the nerves and the spinal cord. The brain is the commander of the human body. It commands the body to do things. The nerves are the connectors, they pass messages to the brain. And the spinal cord is where nerves lie.

Basically, the brain, the cerebellum, and the spinal cord are the main parts.  There are other parts, but those are the main parts.

Spinal cord, brain, cerebellum, neurons

The principle organ in the human nervous system is the brain, which forms part of the central nervous system. The main nerves that lead out of the brain form the spinal cord, which extends from the base of the brain to the bottom of the back. Nerves branch out from this a reach into every part of the body. Once the nerves leave the spinal column, they are said to belong to the peripheral nervous system.

The peripheral nervous system is divided into two parts, the somatic and autonomic nervous systems. The somatic system is responsible for controlling voluntary actions - those that you consciously decide to do - and the autonomic system keeps control of the involuntary body functions such as breathing and heart rate. Some of these can be overridden by the somatic system - you can hold your breath for example, but some cannot. Most people cannot will their heart rate to slow down but it can be changed by behaviour (if you want it to beat faster, you run about!).

I believe the main parts are the brain, spinal cord, and the nerves throughout your body.

The major parts of the nervous system are brain,spinal cord and the nerves cell.

The main parts of a human nervous system are the brain,spinal cord,cerebellum,cerebrum and others

There are only two main parts.they are the central nervous system and the peripheral nervous system. The central nervous system consists of the brain and the spinal cord and this takes responsibility for processing the sensory data that comes from our senses and with this information it has to sort out and filter in order to produce an appropriate response. The peripheral nervous system links the central nervous system to the parts of the body. So once a response is produced I will travel down the spinal cord from the brain to the muscle or artery required and it does this via the nerves of the peripheral nervous system

I wanted the central nervous system .I have been like 5 hours making my homerwork and I don´t find it on internet
