The history of stroke starts with Hippocrates, the father of medicine who first acknowledge stroke more than 2400 years ago. At this time stroke was called as “apoplexy”. Doctors had little proficiency of the anatomy and function of the brain, the origin of the stroke, or how to handle it. It was not until the mid of 1600’s that Jacob wafer discovered that the patient who died with apoplexy had bleeding in the brain. In 1928 apoplexy was divided into categories based on the causes of the blood vessel

affect a person’s heart rate. Studies have shown that movies can be one of these factors. Different genres of movies would affect the heart rate in different ways. The higher the intensity of the movie, the higher a person’s heart rate will be. The purpose of this experiment would be to find which amount of horror will affect a person’s heart rate the most. The hypothesis for this experiment would be if there are more aspects of horror, then the heart rate will increase, when heart rate is a function

Diagnosing COPD is multifactorial, as stated previously, an all-encompassing nursing assessment and patient history must be conducted. When these processes are finalized, and subjective evidence points towards COPD, it is necessary to confirm the diagnosis with objective data. The definitive way to do this is by conducting pulmonary function testing (PFT); specifically, spirometry. On top of diagnosing, spirometry, is also pertinent for staging the patients COPD (Corbridge,et al., 2012). In addition

Normal Heart Rate Chart The heart is an organ located just behind and slightly to the left of the breastbone, and pumps blood through a network of veins and arteries known as the circulatory system. The right atrium is sent blood from the veins, and delivers it to the right ventricle. It is then pumped to the lungs where it is oxygenated. The left atrium collects the oxygen enriched blood from the lungs and delivers it to the left ventricle, where it is pumped throughout the body, and the ventricle

This is why Clegg says ‘’ heart responds to the demand of the body especially skeletal muscle whose demand for oxygen can increase up to 21 times during exercise (Clegg,1995). The flowing pattern of blood changes during an exercise because the blood vessels supplying the muscles stretches and become wider to receive more blood full of oxygen and nutrients. It causes more blood than usual to be flowing in and out of the heart. This will help to meet up with the metabolic demands

His heart had stopped beating. It is hard to describe how I felt in that moment as I am still trying to process my emotions. I remember turning away from the table where the patient lay lifeless, and staring at the sink in the far corner. A single tear rolled

Exam 2 Sheryl Flowers PART I Why are some of us more prone than others to coronary heart disease among other health problems? Be specific in your answer. Type A personalities secrete more of the hormones that accelerate the build up of plaque on the hearts artery wall Chronic stress also contributes to inflammation which heightens the risk of clogged arteries and depression. PART II What is the relationship between language and thinking? Be clear and explain. Language influences thought. The

The advent of technology has significantly increased the amount of time we spend in front of screens. What does this mean for eye health? Constant technology use often leads to ocular discomfort, minor eye ailments and eventually long term sight defects. Most digital devices we use today emit blue light that negatively impacts eyesight and consequently one's overall health. Harmful Effects of Technology on Eyes. Tension Headaches. Dark print on dazzling white background leads to eye muscle strain

By Jonas Wilson, Ing. Med. Malrotation of the gastrointestinal tract Gastrointestinal (GI) malrotation, sometimes referred to as incomplete rotation or intestinal nonrotation, is any deviation from the physiological rotation and/or fixation of the GI tract during embryonic development. During the development of the GI tract, the 3 parts of the tract, namely the fore-, mid- and hindgut, normally bulge out of the abdominal cavity and undergo a counterclockwise rotation of 270 degrees. This rotation

With conflicting research and hardly valid data, to say that phantom limb syndrome is solely caused based on psychogenic mechanism of the patient is inaccurate. More recent research has strongly suggested peripheral mechanism to also be a factor in phantom limb syndrome. Once amputation of a limb or part of a limb is performed, a neuroma is created. Neuromas result from a trauma to the nerve and are typically formed on the site of an inquired sensory nerve, forming a knot in the area. The knot is
