Basic Parts of the Brain and Their Responsibilities

The scarecrow needed it, Einstein had an excellent one, and it can store a whole lot of information. The brain is the control center of the body. Think of a telephone operator who answers incoming calls and directs them to where they need to go. Similarly, your brain acts as an operator by sending messages to and receiving messages from all over the body. The brain processes the information it receives and ensures that  messages are directed to their proper destinations. Neurons The brain is composed of specialized cells called neurons. These cells  are the basic unit of the nervous system. Neurons send and receive messages through electrical impulses and chemical messages. Chemical messages are known as neurotransmitters and they can either inhibit cell activity or cause cells to become excitable.   Brain Divisions The brain is one of the largest and most important organs of the human body. Weighing in at about three pounds, this organ is covered by a three-layered protective membrane called the meninges. The brain  has a wide range of responsibilities. From coordinating our movement to managing our emotions, this organ does it all.  The brain is composed of three main divisions: the forebrain, brainstem, and hindbrain. Forebrain The forebrain is the most complex of the three parts. It gives us the ability to feel, learn, and remember. It consists of two parts: the telencephalon (contains the cerebral cortex and corpus callosum) and the diencephalon (contains the thalamus and hypothalamus). The cerebral cortex allows us to understand the mounds of information we receive from all around us. The left and right regions of the cerebral cortex are separated by a thick band of tissue called the corpus callosum. The thalamus acts as a telephone line of sorts, allowing information to get through to the cerebral cortex. It is also a component of the limbic system,  which  connects areas of the cerebral cortex that are involved in sensory perception and movement with other parts of the brain and  spinal cord.  The hypothalamus is important for regulating hormones, hunger, thirst, and arousal. Brainstem The brainstem consists of the midbrain and the hindbrain. Just as the name suggests, the brainstem resembles the stem of a branch. The midbrain is the upper part of the branch that is connected to the forebrain. This region of the brain sends and receives information. Data from our senses, such as the eyes and ears, are sent to this area and then directed to the forebrain. Hindbrain The hindbrain makes up the lower portion of the brainstem and consists of three units. The medulla oblongata controls involuntary functions such as digestion and breathing. The second unit of the hindbrain, the pons, also assists in controlling these functions. The third unit, the cerebellum, is responsible for the coordination of movement. Those of you who are blessed with great hand-eye coordination have your cerebellum to thank. Brain Disorders As you can imagine, all of us desire a brain that is healthy and functions properly. Unfortunately, there are some who suffer from neurological disorders of the brain. A few of these disorders include Alzheimers disease, epilepsy, sleep disorders,  and Parkinsons disease.

People are Obsessed with Social Media - 1679 Words

1. Introductory Statement It is no secret that the current generation is obsessed with media. You cannot walk anywhere without seeing teenagers, adults, and even kids using technology and social media. Everywhere you look there are ads to purchase the latest and greatest clothing, technology, or beauty products. Television standards have been lowered by the FCC and shows with explicit content have now taken over television leaving teenagers to idolize a lifestyle that is not to their best interest. But how does this media really affect us? What age is most drawn in and how does it change the outlook of their future? This would fall under evaluation research, I am seeking to find out the impact that media has on the current generation.†¦show more content†¦In each segment of life, an emphasis is placed on cultural and environmental factors. According to Arnett, Persuasive evidence for the inï ¬â€šuence of technologies on pubertal timing comes from historical records showing a steady decrease in the average age of menarche in Western countries from the mid-19th to the late-20th century (Arnett 2012, p.497).† The report goes on to claim that secular trends, changes in characteristics of a population over time, that girls are beginning puberty at a much earlier age. A majority of reports show that early maturation in girls has largely negative effects. It exposes ladies to numerous problems such as depressive moods, negative body image, eating disorders, problems at school, and conflict with parents. In correlation with the emphasis mass media puts on the materialistic beauty of women and their size zero bodies, this constantly makes girls vulnerable to achieve this ideal body type. Studies have also proved that these effects can range from strictly adolescent age or long-term until adulthood. On the opposing side boys generally benefit from early maturation, gaining favorable body image and the attraction of the opposite sex.

Immense Environmental Sustainability Issueâ€Myassignmenthelp.Com

Question: What Is The Immense Environmental Sustainability Issue? Answer: Introducation It is undeniable that I have observed immense environmental sustainability issue due to the usage of non renewable electricity and energy. With the current environment the raise of global warming has become a major concern for the people belonging to society. Due to the emission of non renewable energy the rate of environmental pollution is getting high day by day. People are getting affected by unexpected diseases. In addition, environment fails to maintain ecological balance (Rogner et al., 2012). Consequently the rate of marine pollution is getting high. Social people are unable to maintain their daily lifestyle. Due to the extreme rate of usage of non renewable energy the economy is getting affected day by day. In order to overcome this kind of situation, people can increase the rate of using solar energy in order to avoid environmental pollution along with maintaining an ecological balance. As per my point of view the matter of environmental sustainability issue should be taken into a serious consideration. In the high rate of global warming has damaged the ecological balance of environment. People are facing challenges in leading a normal day to day life. In this kind of situation, human being can take some initiatives for overcoming the increased rate of global warming (Zhang, Gari Hmurcik, 2014). The usage of solar energy can recycle electricity. As a result, the users do not have to face challenges in losing the energy resources. In addition, the economic strength does not get hampered due to the use of solar energy.

The Big Bang Approach

Introduction Companies have to choose from various options including the big bang, the phased roll and the parallel implementation approaches when implementing an ERP (Brown at al, 2012). There is, however, no straight answer as to which approach is best since every company is unique in terms of need and the capacity to implement the approach.Advertising We will write a custom case study sample on The Big Bang Approach specifically for you for only $16.05 $11/page Learn More Changing from one ERP to another is, however, not a simple decision since it holds all the potential to make-or-break the firm (Khanna and Arneja, 2012). Companies thus have to take various considerations before choosing the approach. Some of the critical factors include; the cost of implementation, the level of risk acceptable to the company and the size of the business (Khanna and Arneja, 2012). The big bang approach of implementing ERP happens in one major action where all users m ove to the new system on a given switch-on date (Brown at al, 2012). The phased roll approach, on the other hand, happens over an extended period of time and in phases (Brown at al, 2012). The users are, therefore, introduced to the new system in calculated steps. The parallel adoption, though not very popular, is more of a hybrid of the two approaches. It allows both the legacy system and the new ERP to run at the same time (Brown at al, 2012). The users are allowed to learn the new systems, while still working with the legacy system. NIBCO’S big bang The big bang approach is a high risk ERP implementation decision. It requires a lot of planning and well calculated fall back options (Khanna and Arneja, 2012). The successful implementation of this approach by the NIBCO Company can be tied to its good planning. Although the implementation approach is a single-event affair, its successful implementation requires enough time to plan and strategize (Khanna and Arneja, 2012). It i s notable that the implementation of the approach at NIBCO started in December 1995, two years before its switch-on date (Brown at al, 2012). The company even went ahead to set up an implementation team, also referred as the â€Å"tiger† team to lead the company through the process (Brown at al, 2012). Apart from sufficient planning, it is also prudent for the firm to have critical minds behind the switch to the new system. It is thus important for the management to ensure that all critical departments are represented in the team tasked with leading the transition process. In the NIBCO Company, for example, the three critical sectors of technology development, change management and business coordination were appointed to comprise the lead team (Brown at al, 2012).Advertising Looking for case study on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Approaches’ pros and cons Despite the enormous risk involved in implementation, there are various factors that work in favor of the big bang approach. It is considerably cheaper than the phased roll approach, which takes a much longer period to implement (Khanna and Arneja, 2012). The process is also quick and since the switch on takes a single date, it is easier to prepare the users technically and emotionally. Another advantage of the big bang approach is that training the users can be concentrated on the new systems since there is no change over training required. The challenges that may arise from the changes are also condensed over a shorter period of time and are, therefore, easy to manage and address. The approach is, however, challenged by the fact that the difficulties are more pronounced due to the shorter implementation period (Khanna and Arneja, 2012). There is also the danger of overlooking some details due to time limitation as well as the limitations that come with inability to carry out an end-to-end system testing. Conclusion As much as the big bang approach is associated with a big risk factor, it is also endowed with the capacity to cause the company great savings in terms of time and money. The greatest secret to a successful implementation of the approach is prudent planning. References Brown, C.V., Dehayes, D.W., Hoffer, J. A., Martin, E. W. Perkins, W.C. (2012).
