Jim Mannoia found himself stuck in traffic on a Los Angeles freeway, his left leg aching from maneuvering the heavy standard transmission in the stop-and-go traffic, sweltering in the heat because his air conditioner was not working and the vehicle was beginning to overheat at the engine level as well as inside the passenger compartment. Worst of all was that the radio was not working. Feeling rightly miserable, he noticed a BMW in the lane beside him, its windows rolled up tight against the heat
Supraventricular tachycardia (SVT) is a heart condition where the heart beats irregularly due to electrical abnormalities. It is fairly common, especially in children and women, yet unfamiliar to most people who are not diagnosed with it. There are three types of SVT: atrioventricular nodal re-entry tachycardia, atrial tachycardia, and Wolff-Parkinson-White syndrome. All three types have the same symptoms during episodes, which can last from seconds to hours and include palpitations, fatigue,
We as individuals and especially as a country, encompass this idea of freedom into our lives. America is known as the land of the free. New Hampshire’s state motto is “Live Free or Die”. America’s documents like the Bill of Rights, Declaration of Independence, and the Constitution, have been called the “Charters of Freedom” (http://www.archives.gov/exhibits/charters/). These charters give U.S. citizens the freedom of press, speech, protest, gun ownership, privacy, and many more freedoms that we use
Transcutaneous nerve stimulation (TENS) forms one of the procedures that have been proposed by various medical providers as an effective method for reducing pain in labor (Mello et al., 2011). In most cases, the application and use of transcutaneous nerve stimulation (TENS) tools involves the emission of low voltage electrical impulse and can vary in frequency as well as intensity. During labor, the transcutaneous nerve stimulation (TENS) electrodes are specifically piled on the lower back in order
range from using electricity, magnets, or even implants to treat depression, obsessive compulsive disorder, and other various illness such as Parkinson’s disease. The better known types of brain stimulation are electroconvulsive therapy, vagus nerve stimulation, repetitive transcranial magnetic stimulation, magnetic seizure
significantly contributes to homeostasis (McCorry, 2006). Most of the sensory input is from the thoracic and abdominal viscera and is transmitted to the brainstem by afferent fibers of the cranial nerve X which is the vagus nerve. After the input is integrated the response is carried out by the transmission of nerve signals of the preganglionic autonomic neurons. So what are some functions of the autonomic nervous system one may ask? Blushing (my favorite) is a response from the frontal cortex and involves
Barbara Lee Fredrickson, a psychologist, introduces a new conception of love to the readers. She tries to simplify the perception of love most people have known for their entire life. The special bonds and magical bond that continues the love for eternity are all myths and lies. Something that poisons our minds to be committed to one another. The definition of Fredrickson’s conception of “love” is more scientific than emotional. When defining love, it is more dependent on the activity of the brain
the other trial being face submersion with breathing. Using a bucket that held about 3 gallons of water, the bucket was filled up with 6-7inches of water. This allowed enough room for the subject to fully submerse the face to ensure stimulation of the vagus nerve. The water was then chilled to 15 degrees Celsius. iWork’s Labscribe 3 software was used to record the subject’s data using a pulse plethysmography and a respiration monitor. This was plugged in and activated to ensure functioning before
et al., 2011). Sinus tachycardia can be caused by different factors within the body including stimulation of the sympathetic nervous system or a blocked parasympathetic system. The autonomic nervous system which controls the heart originates in the medulla oblongata. The vagus nerve is part of the parasympathetic nervous symptoms and slows the heart down. When this block of the stimulation of the nerve occurs the heart cannot slow down (Jevon, 2010). The sinoatrial or (SA) node in the heart seats
Introduction Today, the world has approximately 334 million people living with asthma. . Currently, there is an increasing rate of asthma infections among the people living in the middle and low-income nations. In the United States, statistics published in 2012 indicated that approximately 19 million adults lived with asthma whereas 7 million children had the condition. In 2013, asthma accounted for approximately 3,630 deaths in the United States. Several factors increase the chance of developing
system when they grew up (Keltner). Humans have pressure receptors called Pacinian corpuscles under their skin (Trudeau). When the pressure receptors are stimulated, it sends signals to the vagus nerve, which is responsible for lowering blood pressure and slowing the heart beat (Trudeau). The vagus nerve then releases oxytocin (Trudeau). Oxytocin is defined by Merriam-Webster dict... ... middle of paper ... ...Facts On File, 1818. Web. 24 Mar. 2014. . Shelley, Mary. Frankenstein.

the prescription can be simply altered or changed; and having the ability to taste again will be regained. The tongue is an extraordinary organ and has a significant function to the body. There are several taste buds, taste cells, taste receptors, nerves and signals that are sent to the brain so people are able to enjoy delicious foods. Although many think taste is created by the top of the tongue, it actually starts from the sides and the tip of the tongue. Some may experience loss of taste due

The Mechanism of Negative Feedback Homeostasis means beatified sex. It is an ability of an organism to control its internal environment, that is the composition of their body fluids, for them to survive fluctuating external conditions. Homeostasis is used to describe all the mechanisms by homeostatic control. Maintenance of stability requires control systems capable of detecting any deviation from the usual and making the necessary adjustments to return it to its normal condition. The internal
During many years the role of school nurse was traditionally viewed as one where the nurse cared for students that were injured, applied bandages and gave out ice bags. Throughout the years the role of the school nurse has evolved into one of leadership and management along with many other duties including traditional roles as mentioned above. The services provided by a school nurse range from assessment and screening to coordinating care for regular students as well as students with special needs
Reducing Symptoms in Bulimia Nervosa and Binge Eating Disorder Through Drug Treatment Bulimia nervosa is a chronic psychiatric disorder that haunts the lives of many young women. The disorder is characterized by frequent episodes of binge eating followed by some sort of purging. The purging usually involves self-induced vomiting and can cause great damage to the body. Persons diagnosed with bulimia nervosa have a loss of control over these behaviors. Affecting the lives of 3-5% of young women
The digestive system otherwise known as the gastrointestinal tract (GI tract) is a long tube which runs from the mouth to the anus. It operates to break down the food we eat from large macromolecules such as starch, proteins and fats, which can’t be easily absorbed, into readily absorbable molecules such as glucose, fatty acids and amino acids. Once broken down, these molecules can cross the cells lining the small intestine, enter into the circulatory system and be transported around the body finally
forced expiratory volume in the first second from baseline that may be measured up to thirty minutes following exercise (M&M). Exercise-induced asthma occurs not only in elite athletes and asthmatics, but it can also be found in non-asthmatics. The stimulation of exercise-induced asthma can range anywhere from inhaling allergens to hyperventilation or intense exercise. The management and prevention of exercise-induced asthma is a series of trials to reduce the effects of prolonged bronchoconstriction

Recurrent brief depression includes a depressed mood and at least four other symptoms of major depression that do not meet the full criteria of any other depressive disorder. These symptoms must last for at least two days and no more than thirteen days (American Psychiatric Association 2013). These episodes must occur once per month for at least twelve consecutive months in an individual who does not meet criteria for any other depressive, bipolar, or psychotic disorder (American Psychiatric Association
