1. What are the central and peripheral nervous systems? What structures are part of each?
The central nervous system is made up of two parts, the brain, and the spinal cord. The peripheral nervous system is made up of two parts as well, the somatic nervous system and the autonomic nervous system.
2. What are Neurons? Describe the key parts of Neurons, including: Dendrites, Myelin, Axons, and Synapse. To keep it simple, a neuron is a nerve cell. Most neurons are very similar to a typical cell, but have a few structures that set it apart. The main part of the cell is known as the soma, or cell body. In the soma is the nucleus, which contains the genetic material known as chromosomes. A neuron has dendrites, and a

The brain is divided by three main functions: the Forebrain, the Midbrain, and the Hindbrain. These functions in unison to process all received information. The Hindbrain is located at the back to the scull and is the lowest part of your brain! There are an additional three parts to this. The medulla, which controls breathing, good posture, and it regulates reflexes. The cerebellum, which is what gives us motor coordination, and last, the Pons. This part monitors sleep and arousal.
The forebrain is the highest part of you brain. Essentially, it separates humans from all the other animals. This consists of 5 parts which are the limbic system, the thalamus, the hypothalamus, the basal ganglia, and the cerebral cortex. The limbic system processes emotions, how we recognize emotions, and how we express them. The thalamus sorts information coming from all these different parts. The Hypothalamus monitors pleasurable activities and releases hormones in response to emotions. The Basal Ganglia works with the cerebral cortex as well as the cerebellum to help you do movements such as riding a bike. The Cerebral cortex is what makes up 80% of the brain and made up of two

What does the Frontal Lobe do? What can happen if the Frontal Lobe is damaged? The frontal lobe is the part of the brain that is responsible for regulating voluntary movements, decision making, problem solving and motor skills. Towards the back of the frontal lobe is the motor cortex. This part of the brain receives information from other parts of the brain to carry out body movements. When the frontal lobe is damaged a lot of changes can occur. Changes such as in sexual and social habits, attention habits, and an increase in risk taking can all occur. http://psychology.about.com/od/biopsychology/ss/brainstructure_2.htm 9. Study the story of Phineas Gage, especially how he changed after his accident (Wikipedia is a fine starting point for this). How does the story of Phineas Gage compare to the results of your answer to question eight? After Phineas Gage got a 3 foot metal rob driven through his head a lot of damage was done to his brain. What was once an easy going, friendly, appropriate guy turned in to an overwhelmingly vulgar, loud, and quite violent man. He was so different to the point where he was fired from his job for being too nasty to the other workers. The same people he was working well with 10 weeks before. This story I think reflects accurately on the results to question eight. https://www.youtube.com/watch?v=MvpIRN9D4D4 http://www.braininjury.com/frontal-lobe-injury.shtml?gclid=CNq7ncqW8cACFcRAMgodHmAAvw
