An axon that is surrounded by myelin sheath, whether in the central nervous system (CNS) or the peripheral nervous system (PNS), is said to be “myelinated”, while the bare axon is “unmyelinated”. Action potentials travel more rapidly and further in distance along a myelinated axon, this is because they travel by salutatory conduction. This is when the impulse at the first node generates currents that open gated channels…
The cell body is where the dendrites receive the electrical impulse from another nerve cell and start a new action potential. The cell body then deviates to the axon hillock at the base of the cell body, where the action potential begins to propagate. To propagate an action potential, several steps must occur. The cell will first depolarize, meaning the sign inside the cell membrane will flip and amplify toward an electrical signal. This then triggers the cellular response for the action potential.…
Paper Assignment #1 1. Discuss the contribution made by Hodgkin and Huxley (1936) with regard to the process of neural conduction. The contributions made by Hodgkin and Huxley was significant in understanding how the neurons in our body work. They used a giant squid axon because it’s big and therefore makes it easier to measure voltages across the membrane of a cell.…
FIRE! BLOOD! CRY! Three words that perfectly describe the picture in 1940 where all you will see are fire on almost everything, blood on every corner, all are running to live because there is the uncertainty of whether you’ll be able to see the sun shines again when all those darkness where caused by the Land of the Rising Sun. It was the start war where all cruelty started on China that their resistance to Japan’s war expansion in their country had led them to be on the war itself.…
Daniel Gilbert passage is a study on people investing in the stock market. The idea was to figure out who would regret their decision more: The person with money in a stock who refuses to change to another more promising stock, or the person who changed and later realized it was the wrong decision. The obvious prediction would be the person who changed and lost money and/or potential money. Making a wrong move is much worst then not making a move at all right. Nine out of the ten people thought so too.…
Psychologically speaking, as humans, we are wired to think that we have the freedom to act and do based upon our own self judgment. For simplistic reasons, let’s assume that this “freedom” is analogous to free will which is a philosophical idea in which to act freely is to have multiple open futures and possibilities, or to be able to choose between many different choices. Determinism is the belief that every event (including action, choices, and decisions) is the inevitable result of a causal chain of events. In other words, a choice with an action (A) is the inevitable result of an earlier action of an earlier choice. This principle presents a problem for the concept of free will.…
In the book Everything’s An Argument written by Andrea A. Lunsford and John J. Ruszkiewicz, a discourse community is defined as “a group of people who share common interests, goals, values, assumptions, knowledge of a topic… and discursive patterns.” In this paper, I’ll explain how I successfully became a member of my high school’s football team by building a strong relationship with my team mates, paying attention to detail, and going the extra mile throughout practice. I will also be able to carry out my explanation through the usage of ethos, logos and pathos appeals.…
In the book, The Assault on Reason by Al Gore, the first chapter; “Introduction” is an excellent chapter that explains today’s America. Gore’s main point is how news media has changed with time, from the type of information it contains to the way it is spread to civilians. Also by the ways that government uses media as advertainment to win their elections. He also talks about the Founding Fathers plan to have a democratic country and having freedom of speech. Gore mainly argues about how media has changed throughout the time.…
Throughout history, there have been many fabricated phrases used by leaders and governmental authorities in our world. Hence, our past consists of countless inequalities, as well as distinctions between individuals. Nevertheless, in our history, the phrase "all lives matter" was used. The phrase, however, was just a saying, which had no meaning since it falsely claimed something that was not followed. If we analyze the meaning of the phrase "all lives matter", it signifies equality for all.…
In, “Nobody Mean More to Me than You and the Future of Willie Jordan,” June Jordan examines the usage of language by blacks in America as well as its acceptance as a standard language. She uses Black English as a model to speak on the greater issue of the rejection of blacks in America by whites. If Standard or “White” English is the only standard language in America, then blacks are not considered or viewed as equals in America. Jordan believed that her students understood that the language that they chose to identify and speak on a daily basis was not considered the appropriate language in America but she wished to guide her students to the realization of what that entailed. She helped them re-learn the language they grew up with, pointing out the differences it has with Standard English along the way.…
This pattern continues creating a wave of electrochemical potential changes that spread rapidly all the way down the axon known as an action potential. Action potentials follow the all or none rule where they fire at full strength or do not fire at all. Action potentials have also been discovered to be generated from both dendrites and axons however in the past scientist believed it was only generated from axons. The action potential speed is constant as it moves down an axon and depends on factors such as the diameter of an axon and the presence of myelin.…
Final Draft “The Indispensable Opposition” The article “The Indispensable Opposition” written by Walter Lippmann presents readers a cynical interpretation of the ideas of freedom and Democracy in order to prove freedom of speech may not be as great as we have come to believe Firstly, Lippmann develops his argument by stating a man’s right to speak freely and act in opposition is a “noble idea” rather than a “practical necessity”. In other words, the idea of freedom of speech is a product of democratic idealists influenced by the Enlightenment in order to create a government by and for the people. Additionally however, Lippmann reinforces his claim by stating the idea of Freedom is something not written down, seen, or even incredibly valuable,…
Next there is the axon. The axon carries information to other neurons, muscles, and glands. This part of…
What is love, and how men and women define it? For centuries now people have talked about love so much, but what is this thing called love. Well love is an assortment of diverse emotions, states, and mentalities that ranges from interpersonal love to joy. It can allude to a feeling of a solid fascination and individual attachment.…
Descartes perspective in The Official Doctrine emphasizes mostly on humans having both a body, and mind which are constructed of many different properties. These two according to the doctrine are harnessed together in life, but conceivable situations such as death can cause the body, and the mind to come apart, and the internal mind may continue to exist because the mind is essentially private. Ryle argues that Cartesian Dualism is wrong and should be rejected because he beliefs that the doctrine is entirely false in principle, and a category mistake in which he believes that According to Ryle, Descartes commits a category mistake by believing that the mind, and body are two different things which he considers to be incorrect. Ryle believes that the mind, and body are actually one, and doesn’t believe that the mind that is immaterial can control the body that is material.…
