Biological Psychology

Biological psychology is a discipline, it makes very important contribution to the nervous system. I will be briefly going over biological bases of behavior and the mental processes. The first thing I will be talking about is endorphins. The second thing I will be talking about is the sympathetic nervous system, and the parasympathetic nervous system.
The first thing I’m going to talk about is endorphins. Endorphins are produced by the central nervous system. Endorphins act like a morphine, or heroin, they are responsive to things like pain, stress, trauma, and anxiety. They help with any pain you are having, and eventually kick in and do their job. Also endorphins will give you a runner's high, I have experienced this while doing track or …show more content…
Sympathetic nervous system is part of the autonomic nervous system, it raises your heart rate and blood flow when in an emergency. The sympathetic nervous system will also make your eyes dilate, your mouth will salivate more, and your lungs will increase, and may have sweaty palms as well as the rest of your body. I have had many times when my sympathetic nervous system kicks in, this is when I see snakes, spiders, and also heights. I'm scared to get bit by any spiders or snakes. I hate even looking at them let alone touching them. My house always had spiders and snakes. Then one time I was heading to the basement for my mom to get supper out of the freezer, and It was dark and I stepped on a big three foot black snake. After stepping on the snake I freaked out and ran up stairs, and my heart was racing, I was sweating from being so spooked. My sympathetic system went into play when that event happened. And any time I’m up high somewhere I get nausea, and my heart starts beating fast. Like one time when I was putting up a tin metal roof in carpentry class, it was my first time and I was nervous and scared. The next thing I’m talking about is parasympathetic nervous system. The parasympathetic nervous system conserves your energy, while it slows your heart rate down. The parasympathetic nervous system calms your body down when you're in emergency situations. Parasympathetic nervous system will restore your body, to its normal after going after an emergency, your heart rate, breathing, and blood pressure will go back to normal. I have gone through the parasympathetic nervous system when getting hurt, or after seeing something scary like a snake, my body will soon get back into normal process. I used to be scared of storms, until one time we actually had a tornado hit our house. I was scared when it hit, but now every time we have a storm and my heart would
