1. The structure and function of the nervous system

The structure of the nervous system

The nervous system is comprised of two distinct cell types. Firstly there are neutrons which re considered to be the building blocks of the nervous system. These neutrons are surrounded by another type of cell known as Glial cells. While the neutrons are the building blocks, these cells are the scaffolding, and therefore add structure to the pervious system. As a consequence, there are ten times as many Giali cells as there are Neutrons.

The function of the nervous system

The nervous system has two distinct sub divisions, the somatic nervous system and the autonomic nervous system. The nervous system as a whole connects together, with the neutrons and

For example, the brain itself has various components, which in turn serve a purpose. The Frontal Lobe of the brain is responsible for motor control, reasoning, language and emotions.

Behind the frontal lobe is the Parietal Lobe this part as the brain also has a specific role, this is significant because it contains the somatosensory cortext. This is where the body processes vital sensory information. Most of the brain's auditory processing takes place in the Temporal Lobe.

The Occipital Lobe is located at the back of the brain, this area is responsible for the processing of visual information.

As we can see from this brief description of some of the functions of the brain, we can conclude that the various aspects of the brain each serve a vital component for functions of the body. Much like how one would construct a computer to perform various aspects.

If one of these lobes were to be taken away, or would cease to function that person may be unable to perform certain tasks, effect senses or be unable to receive information in the same way. It could, also effect personality and even normal behaviour
