Sympathetic and Parasympathetic Nervous Systems Essay

Sympathetic and Parasympathetic Nervous Systems - Essay Example The nerve fibers of the  parasympathetic nervous system  are the  cranial nerves, primarily the  vagus nerve, and the lumbar spinal nerves. When stimulated, these nerves increase digestive secretions and reduce the heartbeat. The sympathetic nervous system activates what is often termed the fight or flight response. Like other parts of the nervous system, the sympathetic nervous system operates through a series of interconnected neurons. Sympathetic neurons are frequently considered part of the peripheral nervous system (PNS), although there are many that lie within the central nervous system (CNS). Sympathetic neurons of the spinal cord (which is part of the CNS) communicate with peripheral sympathetic neurons via a series of sympathetic ganglia. Within the ganglia, spinal cord sympathetic neurons join peripheral sympathetic neurons through chemical synapses. Spinal cord sympathetic neurons are therefore called presynaptic (or preganglionic) neurons, while peripheral sympathetic neurons are called postsynaptic (or postganglionic) neurons. At synapses within the sympathetic ganglia, preganglionic sympathetic neurons release acetylcholine, a chemical messenger that binds and activates nicotinic acetylchol ine receptors on postganglionic neurons. In response to this stimulus, postganglionic neurons principally release noradrenalin (norepinephrine). Prolonged activation can elicit the release of adrenaline from the adrenal medulla. Once released, noradrenalin and adrenaline bind adrenergic receptors on peripheral tissues. Binding to adrenergic receptors causes the effects seen during the fight-or-flight response. These include pupil dilation, increased sweating, increased heart rate, and increased blood pressure. Sympathetic nerves originate inside the vertebral column, toward the middle of the spinal cord in the

Why Obama Won - Assignment Example By taking into concern the current situation of this contemporary world, it can be stated that the political parties need to become market-oriented, by recognizing public demands and most importantly, by designing an effective party product. In this similar context, the party product may comprise certain important factors including policies, constitutions, symbols, organizations and ideologies. It has been apparently observed that an effective political marketing imposes significant impacts upon several important aspects which include political decisions, market orientation strategies, online association marketing and media coverage initiatives (Marshment & Rudd, n.d.). Besides, the notion of political marketing is also viewed as a sort of commercial marketing that emphasizes upon forming, preserving as well as improving long-term interrelation with the voters for the purpose of attaining significant success and expected objectives (Shaughnessy, 2001). In addition, an effective polit ical marketing is all about shaping and delivering accurate message to the key audiences in order to obtain considerable success, especially in the political field (Ren Scott Creative Marketing, n.d.). In this discussion, a detailed analysis will be taken into concern regarding how an effective political marketing supported US President Barack Obama succeed in defeating Mitt Romney to earn a second term. Analysis Brand Difference of Obama and Romney Considering the recent changes in the US political environment, it can be stated that it is the democratic brand which mainly differed Obama from Romney who possessed republican brand. A major difference that can be viewed in this regard is that Obama largely supported the ideas as well as the policies based on Democratic Party while conversely, Romney deciphered strong concern towards Republican Party’s theories and concepts. Furthermore, US President Obama, from the very beginning, was observed as much keen towards introducing a s well as developing significant democratic policies concerning international relations, supporting legalization particularly for illegal immigrants and augmenting employment opportunities among others. These quality facets of democratic policies can be viewed as a significant factor which contributed to the success of Obama helping the common people to interpret the policies as mainly formulated for the interests of the nation (Carothers, 2012). This significant aspect, i.e. the democratic brand of Obama might have significantly assisted him to attain success and win for a second term as US President by a large extent. The democratic branding of Obama evolved over the course of the campaign when he included republican idea into his proposal relating to health insurance reform. According to the proposal, a few of the initiatives based on republican ideas have been taken into concern under the guidance of Obama. In this regard, the initiatives included facilitating varying health ins urance premiums on the basis of participation in programs relating to employer wellness, establishing standardized mechanisms to enhance healthcare quality and superior access towards different community based health centers (The White House, n.d.). Conversely, the republican branding of Romney evolved over the course of the campaign when he acclaimed prior to the election that it is possible to mitigate the loss of revenue resulting from tax cuts by eradicating different deductions as well as exemptions, especially for the upper-income individuals of the US. However, a few of the republicans were significantly criticized regarding the viewpoint of Romney regarding the
