Brain Function Essay Example for Free

Brain Function Essay A Neuron is a specialized nerve cell that receives, processes, and transmits information to other cells in the body. Basically, it is the messenger cell responsible for receiving and transmitting information. Neurons are the information processing components of the brain, each part of the neuron is responsible for receiving and transmitting information. Each neuron please do use role in the communication of the flow of information throughout the body. Neurotransmitters neurotransmitter Chemical substance through which one neuron sends a message to another. A neurotransmitter is a chemical substance that helps communicate information throughout our brain and body by relaying signals between neurons. neurons to occur. Numerous neurotransmitters affect the way a person behaves, learns, emotions, and sleep. Some also affecti mental illnesses. Some examples of neurotransmitters which affect our learning and development are; Acetylcholine affects a persons voluntary movement, learning, memory, and sleep. Dopamine affects a persons movement, attention, and learning. Axon An Axon is a long, slender projection of a nerve cell, or neuron, that typically conducts electrical impulses away from the neurons cell body  transmiting neuroal signals. The axon is the tail-like part of the neuron where sinformation exits the cell. It helps in the transmit information. The function of the axon is to transmit information to different neurons, muscles and glands. Myelin sheath Myelin sheath is an insulating envelope of myelin that surrounds the core of a nerve fiber or axon and that facilitates the transmission of nerve impulses, formed from the cell membrane of the Schwann cell in the peripheral nervous system and from oligodendroglia cells. Myelin sheaths three main functions include are protecting the nerve fiber, insulating the nerve fiber and increasing the rate and efficiency of the transmission of conduction of the nerve impulse. Dendrites Dendrites are a short branched extension of a nerve cell, along which impulses received from other cells at synapses are transmitted to the cell body. Dendrites are treelike extensions at the beginning of a neuron that help increase the surface area of the cell body. These tiny protrusions receive information from other neurons and transmit electrical stimulation to the soma. Dendrites bring information to the cell body and axons take information away from the cell body. Synapses The area where two neuron connect allow transmission of information to occur from one to the other. The messages flow across one neuron to the next through this small gap which separate the pair. . 1. In order for neurons to properly communicate, an electric pulse must occur. It happens as it travels down an axon to the synaptic terminal where the impulses trigger the vesicles to move which contain the neurotransmitter. It is said that most learning is though to involve the change between neurons and synapse. Learning consists of strengething synapses that are already there or by the creation of new ones. Sometimes, eliminating some helps. By learning new things we must realize that our old thoughts aren’t accurate and replace them with new ones in order to change the thoughts and behaviors we once exhibited. (Bruer Greenough, 2001;Lichtman, 2001; Merzenich, 2001). â€Å"Historically, theorists and researchers have believed that the physiological basis formost learning and memory lies in changes in the interconnections among neurons— in particular, in forming new synapses, strengthening existing ones, or eliminating counterproductive ones.†(e.g., Merzenich, 2001; M. I. Posner Rothbart, 2007; Trachtenberg et al., 2002) progress . Cortex cortex Upper part of the brain; site of where complex, conscious thinking processes takes place. It is the large lumpy area that covers the sides of our brains. â€Å"The  area of the brain immediately behind the forehead—the prefrontal cortex—seems to be the primary headquarters for working memory and its central executive, although all of the cortex may be active to a greater or lesser extent in interpreting new input in light of previously acquired knowledge† (Byrnes, 2001; Gonsalves Cohen, 2010; Huey, Krueger, Grafman, 2006; Nee, Berman, Moore, Jonides, 2008). This is the main area that the learning process occurs. Synaptogenesis Universal process that occurs in early brain development in Which cause the formation of numerous synapses. Being able to think more complex and eddicent thoughts, development change in this brain must be the first thing to happen, which is done by synaptegeneis. â€Å"neurons begin to form synapses long before a child is born.  But shortly afterbirth the rate of synapse formation increases dramatically. Neurons sprout new dendrites in many directions, †¦life. Much of this early synaptogenesis appears to be driven primarily bygenetic programming rather than by learning experiences. â€Å" (Bruer, 1999; C. A. Nelson, Thomas, de Haan, 2006). Synaptic pruning Synaptic pruning is the process when old formed synapses wear away due to universal process in the brain development. A developmental process that eliminates â€Å"nuisance† synapses that are inconsistent with typical environmentalevents and appropriate responses. Synaptic pruning, then, may be Mother Nature’s way of making the brain more efficient (Bruer Greenough, 2001; Huttenlocher Dabholkar, 1997; Spear, 2007). Adults and children happen to form new thoughts and synaose based on expierence and new discovery. They replace one thought with the other they learning through these developments. Myelination Myelination is the formation of fatty substance around the axons of the neurons. This is what helps speed up the electrical pulses therefore speeding up the transmission of the messages and information shared between the pair of neurons. As myelin is created over neuron transmissions more quickly, greatly enhancing the brain’s overall efficiency. Myelination continues throughout childhood, adolescence, and early adulthood, especially in the cortex (Lenroot Giedd, 2007; Merzenich, 2001; Paus et al., 1999).

Religious Beliefs in Aeschylus Oresteia, Homer’s Iliad, and Sophocles’

Religious Beliefs in Aeschylus' Oresteia, Homer’s Iliad, and Sophocles’ Electra The final and definitive defeat of the Persian army at the battle of Plataea represented the end of an age-long threat to Athens. But the victory was also a miracle, as all the odds were against the Athenians at the onset of the war. While Pericles took charge of Athens after the war and started the advance of democracy, religion also thrived. The rebuilding of the Acropolis and the construction of the Parthenon and its great statue of Athene under Pericles' rule signified the height of religious belief among Athenians. However, the shift in power from the aristocrats to the common men in the new democracy, and the Peloponnesian War and Great Plague that followed the shift, all contributed to a general decline in religious belief. Only a few decades after reaching its peak, it reached an all-time low. This change in attitude among Athenians can be observed by comparing the works of two tragedians, Aeschylus and Sophocles, whose plays were performed in each of these two periods. But e ven with this dramatic shift, it is clear that Athenians remained believers throughout these periods, because religion was, and always has been, a huge part of their culture. The religious view of Athenians before the Peloponnesian War can be best demonstrated by the portrayal of interaction between men and Gods in Aeschylus’ work, The Eumenides. From the first scene, when â€Å"The doors of the temple open and show Orestes surrounded by the sleeping Furies, Apollo and Hermes beside him† (Aeschylus, 137), one can see that in Aeschylus’ eyes, Gods and Goddesses are not something distant and unreachable, but instead, they are â€Å"real† figures who will at times stand by our s... ...ardless of how "good" or "bad" they were, and despite constant worship the Gods did not intervene. Having witnessed such horrors, it is understandable that people of those times, such as Sophocles, would have taken a step back and wondered if the Gods were actually there. Having gone through a period as such, it is only natural for even the most faithful to doubt a little, which was evident from the absence of interaction between Gods and men in Sophocles’ work, Electra. However, it is clear as had been previously pointed out, that while belief in the literal truth of the myths was suppressed, the Gods did live on in the hearts of the Athenians.

Job Stress An Essential Component Of Communication

Certain occupations tend to be more stressful than others, and nursing is widely considered to be one such profession. Over the last 10 years, nurses consistently reported the highest levels of job stress out of all healthcare professionals (American Nurse Association, 2011). Job stress is noted to cause harmful physical, psychological and emotional responses which occur when the needs of the job do not meet the needs of the worker. Amongst nurses, the highest sources of stress are due to the heavy workload, poor management, professional conflicts, and the emotional demands of caring for the patients. A stressful event occurred during a nursing 12-hour shift that started with a poor shift report from the previous night shift nurse. The transfer of accurate information and the responsibility for the care of the patient from one nurse to another is an essential component of communication in the healthcare setting. When the nurse receives a poor shift report and inaccurate information about her patients, it puts a lot of pressure on the nurse and leads to frustration. The nurse then spends a lot of time trying to get accurate information from the patient’s chart. Working in the telemetry floor, they should have stable patients since the ratio is 1:4. However, with an assignment of 4 patients, one of the patients the nurse had to take care of was a critically ill patient with a blood pressure reading of 62/25, heartrate of 170, oxygen saturation level of 90% on 6 liters ofShow MoreRelatedMotivation, Stress, and Communication in the Work Environment1300 Words   |  5 Pagesï » ¿Running Head: Motivation, Stress, and Communication Motivation, Stress, and Communication Motivation, Stress, and Communication As the world has crossed the threshold of twenty-first century, the phenomenon of business community has transformed, resulted in a more competitive world.
