Biology of Psychology
In this class, I learned about 3 types of neurons in the peripheral nervous system: sensory, interneuron and motor neurons. Neurons are made of several parts: the nucleus, dendrites, the cell body, axon, Schwann’s Cells, Myelin Sheath, Node of Ranvier, and axon terminals.
(B is cell nucleus and the other line is cell body, it wasn’t visible in the image)
These neurons have an electrical charge called action potential that moves down the length of the neuron as a result of the movement of positive ions into and out of the axon. This potential has 3 parts to it: depolarization, repolarization, and the refractory period.
In the depolarization stage, channels in the membrane open allowing Na+ to flow into the axon and this incoming message stimulates the axon. With this, the voltage increases.
In the repolarization stage, along with the existing channels, new channels open that allows K+ to exit the axon which results in a voltage decrease.
Refractory period happens after repolarization and during this time Na+ is inside and K+ is outside of the axon. To be able to go through this cycle again, the pumps inside the axon push Na+ ions outside while K+ goes back inside, which was how this cycle started in the first place.
Synapse is the section between 2 nerve cells where a signal is sent from the axon to the dendrites. It has several parts like the axon terminal bulb, the synaptic gap, synaptic vesicle, pre-synaptic membrane, NT receptors and neurotransmitters, the axon of the sending neuron, dendrites, and post-synaptic membrane.
The axon terminal bulb produces neurotransmitters, and the synaptic vesicles store them. These neurotransmitters send signals by binding with the receptors on the post-synaptic membrane of the receiving neuron after moving in the synaptic gap after action potential gets transferred from the axon to the axon terminal bulb.
The receiving neuron decides to send its own action potential based on if the received NT message is excitatory or inhibitory. Excitatory means it stimulates AP while inhibitory represses AP. If the message is more excitatory than inhibitory, the receiving neuron will send its own action potential, but if inhibitory is more than excitatory, it will not.
Psychology Core Competency Critical Thinking
on In psychology 12, I used the critical thinking competency the most. Some of the problems I’ve encountered were unfamiliar terminology/vocabulary while researching about disorders, not being able to find reliable sources for my DSM, having to study twice as hard to cover for all of the lessons i missed while I was absent, how to make my concept map, etc. These were really stressing me out, but I took everything slow and steady. First, I brainstormed ideas about how to do the concept map and discussed with my friends for more ideas and their suggestions, which helped me make the concept map quicker and easier. When I encountered unfamiliar words, I googled them and added them in my vocabulary for future use. When I missed classes, I got help from my teacher and friends to get back on track, while also keeping up with the new assignments and tests coming up. I also studied at home which made things easier. Writing the personal DSM took me a really long time, as I had around 22 full pages in it. At first, finding reliable sources were difficult as a lot of fake websites popped up in my feed and with virus ads, so I was a bit cautious. But eventually, I identified which websites were trustworthy and which were not, so I just used the ones I deemed reliable. With the sources I used, I was able to write 22 pages and finish my DSM with no further problems other than getting no sleep and rest. At the end, I didn’t give up and got over the obstacles I encountered through will power and thinking critically. Dedication and determination is what got me here.

on Narrative Essay Reflection CK
on The narrative essay allowed me to analyze my way of doing things and it encouraged me to try new things with it. While writing the essay, I researched about many new rhetorical devices to use in my essay that I hadn’t used in the past, and these devices gave me the knowledge needed to finish my essay in a proper manner. My horizon expanded, and I started to look at things from different perspectives to write a good essay. It boosted my skills and made me go beyond my capabilities. At the end, I had written over 1500 words while the word cap was 1250. I was so inspired that I had gone beyond the word cap, so I had to cut some parts out. Trying out new ways to write an essay and including different rhetorical devices in it really improved my skills in writing and English overall. I feel like it was pretty successful, and next time, I will try to include even more and different stuff in my future essays. My goal for the future is to get into a good university by studying hard, keeping track of important events and being responsible. After I get into university, I will study even harder to get a proper job and live my life the way I want to.
