Methamphetamine and its Effects on the Body and Brain Methamphetamine (n-methyl-1-phenyl-propan-2-amine) has a molecular weight of 149.237 g/mol and is an addictive man-made stimulant affecting the central nervous system (Methamphetamines: An Overview, n.d.). There are two different types of methamphetamine: l-meth (Levo-methamphetamine), and d-meth (Dextro-methamphetamine), which is the more common form. It is 2 to 10 times as physiologically active as l-meth (Crystal Meth Facts, n.d.).…

1. Nerve conduction tests of the ulnar, tibial, and peroneal nerves involves testing how well and quickly a nerve can send electrical signals to begin contraction of skeletal muscles. The first step in muscle contraction is excitation of a skeletal muscle fiber by a nerve signal. The nerve signal must be sent to the neuromuscular junction to open the voltage-gated calcium channels. Just like in a muscle fiber, the neuron must reach threshold potential before the action potentials can be…

Introduction of Patient My patient is Freda Wilson, a 64-year-old Caucasian female who resides in Shawnee, Kansas with her husband. Mrs. Wilson is 5’5” tall and weighs 148 pounds, has two adult children, and is a relatively healthy individual.

Human beings in the past hunted and gathered for subsistence. This culture, also known as the “foraging culture” included strategies like hunting, trapping, fishing, and gathering, in order to obtain supplies. These behaviours placed demands on the body that are similar to vigorous exercises and were practiced by all humans, until 12,000 to 11,000 years ago, “when agriculture and animal domestication emerged in southwest Asia and in Mesoamerica”. Innovations such as agriculture and animal…

In recent years, developments in the technologies used by law enforcement organizations have been continually accelerating. Technology, from less-lethal devices, such as TASER, and forensic evidence to advanced crime analysis, aims to shape law enforcement and has redefined multiple aspects of policing (White, 2014). One of the most recent technologies is police body-worn camera system, which has already received extensive attentions among media and policing executives in 2013 (White, 2014). In…

The patient (pt) in room 584 is an 84-year-old Caucasian woman who was transferred to Lynchburg General hospital on December 12, 2016 from Stonewall hospital in Lexington in order to receive pulmonary care. Though she was admitted for unspecified dementia without behavioral disturbances, she was originally hospitalized at Stonewall since September 21, 2016 for atrial fibrillation with a low ventricular response rate, and dyspnea. She has co-morbidities of Parkinson’s disease and Lewy body…

Embryonic Stem Cells: The Cell of Many Potentials According to renowned physicist Stephen Hawking, “Stem cell research is the key to developing cures for degenerative conditions like Parkinson 's and motor neuron disease from which I and many others suffer. The fact that the cells may come from embryos is not an objection, because the embryos are going to die anyway.” Stem cells are undifferentiated cells that have two important abilities. Firstly, they have the ability to renewed themselves…

Background Neurodevelopment is defined as “the dynamic inter-relationship between genetic, brain, cognitive, emotional, and behavioral processes across the developmental lifespan [1].” Neurodevelopmental disorders are defined as a group of conditions caused by damage to the neurological development process which cause long term delays in development. These disorders normally begin in infancy, when development is most crucial, and remain fairly consistent throughout adulthood. Neurodevelopmental…

IRISH TERRIER ORIGIN AND HISTORY The Irish terrier is one of the older terrier breeds. Its solid red coat and long, sleek body distinguish it from other terriers. Earlier Irish terriers were black and tan, grey and brindle with the solid reds appearing at the end of the 19th century. In 1879 Champions Erin and Kilney Boy appeared at a show in Glasgow and are considered the mother and father of the breed. During that era the Irish terrier was one of the most popular breeds both in England and…

I have recently read five Times Magazine articles, and I have come to further my intelligence. I have learned about a lot of new ideas, how people react to these ideas, and if these ideas are good or bad for our human intellect. After examining human intelligence through reading these five Times Magazine articles, it is quite obvious that the world is experiencing new ideas and ways of living, but humanity has a unique form of intelligence which I will refer to as stubbornness. Therefore, does…
