sleep, we drift in and out of sleep and can be awakened easily. Our eyes move very slowly and muscle activity slows.When we enter stage 2 sleep, our eye movements stop and our brain waves (fluctuations of electrical activity that can be measured by electrodes) become slower, with occasional bursts of rapid waves called sleep spindles. In stage 3, extremely slow brain waves called delta waves begin to appear.interspersed with smaller, faster waves. By stage 4, the brain produces delta waves…

RECONSTRUCTION Robert Nozick argues that most people would chose not to plug into an experience machine, since it would essentially be a form of suicide, and since most people more than likely care about more than just experiences. The motivation behind this thought experiment is hedonism’s claim that pleasure is our sole aim in life. Nozick argues that if hedonism were true, then everyone would plug in, but since most people would not plug in, hedonism must be false. So, the purpose of this…

Over 100 million animals are tested every year and most are killed in labs the where they had been experimented on (“Experiments on Animals: Overview”). Animals are used in many ways, such as being bred for specific genes, being used as models to replicate human diseases, and being the test subjects for drugs and vaccines to improve human health ("Biomedical Research”). Animals like dogs, cats, mice, rabbits, pigs, chimpanzees and much more are in isolation in laboratories all over the world…

Muscles (Grip strength) In this week’s lab, we was doing an experiment on forearm, and its muscle fiber with nerves. The forearm is a part that between the primates’ elbow and wrist. Forearms contain connective tissue, nerve tissue and muscle tissue. In which, connective tissue is just radius and ulnar bones. However, there are a great deal of muscles and nerves in the forearm. When a nerve impulse transmission to synaptosomes induced depolarization, allows calcium ions to enter the cell…

I will be discussing two diseases that require diagnostic test identifying them from the body system. The first disease will be from the cardiovascular system pertaining to congestive heart failure (CHF) and the second will be from hepatobiliary system concerning gallstones. This paper will cover topics such as: certain test that are required; how the test works; the information obtained from the diagnostic test; and does another diagnostic test need to be conducted in order to confirm a…

Conclusion Since the beginning of the twenty-first century, the total prescriptions per year in United States have increased rapidly, and the study done above confirms that these increasing prescribing rates are causing significant damage to the country’s health. As the number of prescriptions increase, the amount of prescription harm recorded not only follows but increases at a significantly higher rate. This disproves my original hypothesis and indicates that the prescription process is…

pacemaker cells that fire so rapidly that the upper chambers of the heart quiver instead of beating efficiently. In catheter ablation, a doctor inserts long, thin tubes (catheters) into your groin and guides them through blood vessels to the heart. Electrodes at the catheter tips can use radiofrequency energy, extreme cold (cryotherapy) or heat to destroy these hot spots, scarring the tissue so that the erratic signals are normalized. This corrects the arrhythmia without the need for medications…

primitive method for clinical cardiac pacing was achieved many years later by a Boston cardiologist named Paul Zoll. In 1952, Zoll reported successful resuscitation of two patients who were suffering from ventricular standstill by placing external electrodes onto the anterior chest attached to a remote electric pulse generator (Ramsdale & Rao, 2012). Both patients had suffered from Stokes-Adams attacks, which is a life-threatening form of atrioventricular block characterized by episodes of…

Continuing influence of the founders of the company (Rituals) When James F. Lincoln died in 1965 there was concerns among employee that the Lincoln’s system could fail and the profits might drop. The employees were concerned about the continuation of year -end bonuses. Fortunate enough, the company has grown stronger than before. Employee’s bonuses and company profits increase annually. This has led to higher morale and productivity among employees. The company’s employee turnover is…

microphone that picks up speech and transmits the sounds waves through a line attached to the box into the ear of the individual. Lastly, we have Cochlear Implants. Cochlear Implants involve a complex surgery in the head to the ear. They will implant an electrode array behind the ear and attached a line to a stimulator just above the ear. The individual will then place the transmitter, which is magnified on top of the head, over the stimulator, which is also magnetic. Connected to the…
