This week on my blog I’m going to talk about how psychology is related to physics. The term that is used for this topic is psychophysics which is the study of the relationship between the physical and psychological perceptions. I’m sure that a lot of people feel that it is common sense to know why someone is acting or doing things a certain way, but in some cases people have no control over how they behave.

 There are two major nervous systems throughout your body. Your Central Nervous System is basically like armor. Anything that is gets broken such as your brain and spine isn’t fixable. Believe it or not your central nervous system is at maximum growth once you’re around age 12. Another nervous system you have is the Peripheral Nervous System. Your eyes, salivary glands, lungs, heart, pancreas, stomach, spleen, liver, adrenal gland, colon, bladder, and sex organs are basically broken into two smaller systems called the autonomic and the somatic system. The somatic system tells your body what to do. For example: You have to move your legs on your own to run. It doesn’t just happen. However, autonomic system is things your body does automatically. An example of this would be breathing. Within the autonomic system is the sympathetic and parasympathetic system. Through the sympathetic system, certain muscles shut down when something stressful is happening. You don’t digest which causes food to rot while in your stomach. When this happens bacteria starts to eat the lining out of your stomach. This systems process can be summed up by the phrase “fight or flight” which means fight or run. The parasympathetic system always has the go and stop messages sending off.

In the neuron structure there is a membrane which is semipermiable lipid with proteins. Semi means to pass through and lipid means fat. In the lipid bilayer the parts that like water face each other so faces that don’t are on either side. The membrane is NOT a circle; in fact, water pushes and makes it into a sphere shape.

Fun Fact: A long time ago people who died from voodoo would still be alive if there was CPR and more medical help. Within the time someone gives you to live before believed to be your time to die your body is tired and the sympathetic system shuts down. When parasympathetic system is tired it speeds up and sends go signals. Their nervous system shuts the heart off.

 Other Parts of the Neuron Structure:

Soma: without “arms” Dendrites: receive receives information from other cells (input) The axon is output. Axons travel in the same direction to the skeleton. There are branches of axons so that there is a larger effect.

Fun Fact: Your brain is actually grey NOT pink 🙂

 Neurotransmitters are chemicals that are released by a neuron. It can alter activity in another neuron. There is an agonist inside which helps the transmitter do whatever it need to. The antagonist hinders whatever the transmitter is going to do. You need dopamine to be able to move.* There are 5 neurotransmitters that treat depression. Serotonin is a mood regulator; too little of it and you’ll be depressed. Dopamine is used for schizophrenia and Parkinson’s disease. When there is too little dopamine in your system you start to shake and eventually can’t move. But when you have too much it causes you to hallucinate and become paranoid. Inside of you there are endorphins that are being blocked because of pain messages. Street drugs make extra endorphins. Everyone’s body knows what rate you need to be at. While on street drugs your body slows down and eventually stops making endorphins. Big time drug users eventually need it every day because their body will feel like it’s on fire without the drug. Ecstasy causes you to get the bipolar disease.
