nerves system essays 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 of the nerves that branch from the brain and spinal cord. It is a thick bundle of nerve fibers located within the spinal cord. The PNS can be regenerate and it will regrow. The brain and spinal cord are the main parts of the nervous system. The brain controls every part of your body and is located top of our head inside our skull. The spinal cord with controls our movement. Nerve cells contain 3 parts: dendrites, cell body and the axon. Dendrite is the receiving part of the neuron. It is a short extension of the cell body And send signals toward the cell body and the cell body conducts nerve impulses which in the transmission of the nerve impulses from the region to the other cell. The axon is a single extension carries the message to the next neuron, which controls all of the nerves. The nerve impulse is response of the neuron. There are 3 classes of neurons: sensory neurons, motor neurons, and interneurons. Neurons are also called nerve cells. A sensory neuron takes information from a receptor to the CNS. A motor neuron takes information away from the CNS. An interneuron transfer information between neurons in the CNS. It also sending out signal to the muscles resulting in contraction or movement. Nerves impulse occurs when an action potential changes rapidly.

What You Absolutely Need to Know About Changing Careers

What You Absolutely Need to Know About Changing Careers Adaptable. Multi-faceted. Nimble. These flexible qualities are all trending in the current job market- so why is changing careers so difficult? Let’s look at some of the ways you can make a career switch, and get yourself ready to embrace the current job trends and demands. Find Your Career Path(s)Conventional wisdom suggests that we all have a career path, a specific trajectory. You start here, you’ll hit these points along the way, and you’ll end up there. The problem with this is that it sounds great in theory, but more often than not, reality gets in the way: economic downturns, personal life changes, and burnout can all interfere greatly with this linear plan. Plus, many of us choose that career path at a young age, right out of school or as an idealistic twentysomething. Are you the same person you were at 21? I’m not (thank goodness), and as someone with evolving skills and interests, I like to think that I’m not locked into a rigid path.Life coach Roman Krznaric, author of How to Find Fulfilling Work, believes in the concept of â€Å"wide achievers†: the idea that a career can be a composite of diverse jobs and experiences, instead of a straight line through one field. In this model, you’d set your goal as a skill set rather than a specific job title (for example, VP of Marketing). It involves rethinking our careers, and deciding whether you might have multiple paths you can take to the endgame of a satisfying career.But how do you navigate this, if you’re already in a job, or have a ton of very specific experience that may not travel into the field where you want to go next?Make a Smart Start to Your ChangeIf you already have a job, you don’t need to hand in your resignation and jump right into that deep end of finding your next career. Take time to figure out what you want to do. Think you might have an interest in bumping your photography hobby up into a professional photography gig? Try to hustle one or two freelance jobs on nights and weekends, and try to build a client base.If you already know where you want to go†¦You should start by doing a self-assessment:What types of jobs are available to someone with limited experience?What skills do I have already?What are the bare minimum skills required by this field I’m interested in joining?What development do I need?Am I willing to start from the bottom if necessary?If you’re thinking about changing careers and know what your target field is, you can start by taking related classes online or in the evenings, or by attending networking events. Volunteer. Talk to someone who’s already in the field, and ask what their day-to-day is like, and what their job requires. At this point, there’s no commitment- it’s a fact-finding mission.If you’re still trying to figure out what you want your new career to be†¦Ã¢â‚¬ ¦don’t sweat it. You may just know that you want A Cha nge, and need to figure out what happens next. This option is a challenging one, to be sure- you’re starting from scratch. But that’s also the beauty of it: you’re starting from scratch! You don’t have preconceived notions, and can take the time to figure out what you really want to do, and why.Find Hot Career Change IndustriesWhere are the jobs and new opportunities? Right now, there are definite hotspot industries that are friendly to career changers. According to U.S. News and World Report, these fields are perpetually expanding to keep pace with society:Healthcare. With the Baby Boomer population retiring and aging, healthcare needs and demands will continue to explode.Mobile technology. Got coding skills? If not, perhaps it’s time to start taking some courses? While some areas of the tech sector are declining, the innovations happening in mobile technology (apps, communications, etc.) keep on going.Data analytics. Sometimes it feels like we ar e little but a walking, talking collection of aggregated data points. Almost every industry is pulling in massive amount of information these days, and having the skills to parse and analyze that information is a huge selling point.And remember: if you feel intimidated by the idea of starting over and changing career gears, you are not alone.  Be a New-Wave EmployeeA hard truth of jobs in general these days, and for people who are trying to build experience, is that many employers want non-traditional employees. That means employees who fall outside the full-time spectrum. If you’re looking to make the career switcheroo, you should consider job openings that are in your field, but might not be the permanent opportunity of your dreams. These include:Part-time jobsContract/freelance jobsTemporary jobsThis goes back to the flexibility issue I mentioned earlier. Employers value flexibility, because it helps them reach their own goals. And even if your own goal is to find a perm anent, full-time, benefits-laden job in your new field, these jobs can serve as a stepping stone while you pick up needed skills and experience.Build Your BrandBranding is a major part of any job search, but if you’re trying to rebrand yourself as a different kind of professional, it’s essential. You’re building your rep and your network from the ground up, basically, so it’s important to have a clean base. If you haven’t done so already, clean up your existing profiles and get them job-hunt ready. After you’ve done that, start positioning yourself for your new field. Start following strong voices in your new area, read (and post) links to stay on top of trends in the field, and figure out how people already in the field are positioning themselves. This can help you figure out how to best present yourself as your job hunt really gets underway.Social media is one of those perennial megatrends that doesn’t go away- so the trick is stayi ng on top of the new media to figure out where you should be as well. Which platforms are the â€Å"cool kids† using?

With sharp-eyed attention to what’s going on and how you can transfer your existing skills and experience to another field, you’re well on your way. Good luck!
