Neuro Transmission Positive Charge
488 wordsneurotransmitters play a central and critical role in our psychological existence, identity, and experience of the world Neurotransmitters are chemicals that communicate between nerves. In some ways, neurons are like computers: they receive messages, process those messages, and send out the results as new messages to other cells. In the case of neurons, messages consist of chemicals that interact with the outer surface of the cell membrane. This chemical interaction with the cell membrane causes...

Term Side Effects Family Members
1,069 wordsHave you ever believed in something your entire life, only to come to terms that your belief is miss-informed? Recently something like that happened to me. For a speech class I had to do research on a popular drug called ecstasy, used at raves and underground parties. My first take on the drug was that it was very unstable and that it could eventually lead to death. Obviously you believe most stuff you read in the news, and so I took the news to heart about ecstasy. The problem was that the sour...

A Summary Ion Channels In The Membrane
869 wordsA Summary: Ion Channels in the Nerve-Cell Membrane In this article, Richard D. Keynes details the workings of ion channels in nerve cell membranes. Nerve impulses (action potentials) are the unit by which information travels in an organisms nervous system, and the generation of this action potential is dependent on the nerve membrane being permeable to ions which in turn makes said membrane excitable. Electrical activity of a nerve is triggered by a depolarization across the membrane and this al...

Fully Understood Human Brain
725 wordsDopamine As the chemical responsible for the pleasurable sensations felt by the human brain, dopamine has been found to be active in many aspects of every day life. Any physiological action that receives a positive feedback, such as a handshake, a kiss, or the use of a drug, can cause the level of dopamine activity in the brain to increase. Dopamine is a neurotransmitter that relays messages from one neuron to the next. Through axons, neurons influence neurological activity in many regions, spec...

Hydrogen Peroxide Chemical Imbalance
1,140 wordsThe music vibrates throughout your body. Everything you perceive or imagine pulsates in unison to form the collective conscience. Every thought, feeling, and your existence as a whole become euphoric and connected. You love and understand everything as never before. Why does this have to end after a few hours? Why can it not be real? This is your body on MDMA (Ecstasy). Also known as Adam, E, and the love drug, Ecstasy has almost become synonymous with thoughts of druggie teenagers dancing at al...

Peripheral Nervous System Central Nervous System
431 wordsThe Nerves System Nervous System The two types of the nervous system are the Central nervous system and the peripheral nervous system. They are responsible for integrating, processing, and coordinating Sensory data and motor commands the central nervous system, which interprets sensory input and carry information to maintain homeostasis. CNS can t be regenerate because a CNS consists of the spinal cord that mean if it s break the spinal cord is break also. The peripheral nervous system consists ...
