  • Neurotransmitters Essay

    What are Neurotransmitters? The functions of the brain rely heavily on a complex system of communication. The brain’s process of communication is supported by a series of cells called Neurons which submit chemical charges known as Neurotransmitters. Neurons are the foundation for the brain’s functions and consist of three basic parts such as the Cell Body, Dendrites and Axons. The chemical transmissions from Neurotransmitters are the product of messages being communicated from one Neuron to the next through the axon of the cell. This message is better known as an Action Potential, which is “an excitation that travels along an axon at a constant strength”. (Kalat, 1992)Action Potential can be caused by sodium ions traveling through the axon…

  • Emotion In David A. Sousa's Mind, Brain, Education

    There is no doubt that dopamine plays a huge role on cognitive learning, but what would happen if there was a lack of dopamine. Dopamine is a neurotransmitter associated with movement, attention, learning, and the brain’s pleasure and reward system (271). Neurotransmitters are very important because they are what connect everything. They allow our body and brain to work properly. If there is lack or tolerance of neurotransmitters there is many effects it can have on cognitive abilities, but how…

  • Pathophysiology Of Nerve Impulse Essay

    Electrical events propagate a proof at intervals a nerve cell, and chemical processes transmit the signal from one nerve cell to a different or to a muscle fiber. The action of interaction between neurons and between neurons and effector cells occur at the top of the nerve fiber, in a very structure known as conjugation. Touching terribly shut against the nerve fiber of another cell. The nerve fiber releases chemical substances known as neurotransmitters that attach themselves to chemical…

  • Biological Theories Of Depression Essay

    theories and behavioural theories. The biological theories are based on genetic factors and neurochemical factors. The genetic factors are the depressive illnesses that run in families. The risk for relatives of individuals to be diagnosed with major depression is around 5-10%. Researchers found out that the genetics of depression can be transferred with twins, meaning that identical twins share the same genes whereas fraternal twins share about 50% of their genetic material. If an identical…

  • Describe How Neurons Communicate With Each Other Through Electrical And Chemical System Case Study

    Many of you know of Michael J. Fox’s condition with Parkinson’s Disease. What neurotransmitter is thought to be related to the development of Parkinson’s disease? What drugs are used to treat it and what are the drugs doing? The drugs used in the treatment of Parkinson’s disease L-dopa, increasing the creation of dopamine once it’s in the brain, this drug treatment was discovered after injecting dopamine was an unsuccessful treatment because it couldn’t break the blood-brain barrier. By…

  • Similarities And Differences Of Neururotransmitter And Hormones

    Chapter twenty-eight discusses neurotransmitters and hormones. The neurotransmitter is a messenger that travels between a neuron and a neighboring neuron to transmit a nerve impulse. A hormone is also a messenger that is secreted by cells of the endocrine system and transported through the bloodstream to target cells, this is where it is stimulated. There are many similarities and differences between a neurotransmitter and hormones. Neurotransmitters are found in the nervous system. They carry…

  • Alzheimer's Degenerative Disease

    The definitive diagnosis of Alzheimer’s can’t be made until autopsy, when neuronal loss, accumulation of beta-amyloid plaques, neurofibrillary tangles and abnormal tau microtubules are observed (Advokat et al., 2014). The current drugs that treat Alzheimer’s act on brain neurotransmitters, but do not alter the course of the disease (Advokat et al., 2014). Some of the drugs for the treatment of Alzheimer’s disease focus on inhibiting the enzyme that breaks down acetylcholine in the synapse…

  • Adenosine Receptor Caffeine Analysis

    electrical signaling of the chosen neuron is to proportionally quantify the effects the chosen drug-caffeine has on the neurotransmitter Adenosine. Caffeine is a known antagonist of Adenosine, inquiring that it counters Adenosine’s inhibitory effects by a simple mechanism of competitive inhibition – not allowing Adenosine to bind…
