Medulla oblongata

Go ahead and try it. Prick your finger on a pin. Kick a chair leg. Lightly, please - touch a hot stove. Barring an extremely rare disease, you will definitely feel something. Something strange and terrible; or, at least, that is what your brain tells you. You won’t want to touch that pin again; or you will be more careful when passing through the dining room; or you will remember the next time you cook to keep some distance from hot metal - all because your brain has told you to refrain in such…

1. Definition of Asthma: Asthma is one of the most common type of chronic obstructive pulmonary disease (COPD). A COPD is a type of disease or disorder to which the airway is affected and causes breathing to be slowed or forced. Asthma is a type of COPD that causes the airway to become inflamed and to be hypertensive (increased pressures in the blood vessels in the airway) due to any internal or external stimuli. The system that is closely associated with asthma is the respiratory system. The…

quote sets the tone of law and ethics in the medical field.Some aspects of our minds we control ; that we are aware of. However, some aspects of it are ticking in normality and we don’t even have to think about them, these are mechanisms of the medulla oblongata, the control center of basic motor functions. All our decisions of right and wrong, our conscious decisions are our ethics, in the medical field we make a promise to ourselves and others to do what's right. Most medical claims do not…

Six years imprisoned in her own body, unable to communicate with anyone, and with no one knowing she was alert. Julia Tavalaro was 27 when she suffered multiple strokes and fell victim to the rare Locked-In Syndrome. None of her family noticed that Tavalaro was awake or trying to communicate with them, it was a therapists who noticed that Tavalaro seemed to follow her with her eyes. A disease often misdiagnosed by doctors as a vegetative state, or pseudo-coma. She was trapped without anyone…

The main nerves affected in dysarthria are the glossopharyngeal nerve (IX), vagus (X) and hyperglossal (XII), all three of these pairs of nerves originate in the medulla oblongata (Duffy 2013), which is an area of damage for Susan. The glossopharyngeal nerve controls the posterior third of the tongue, part of the pharynx and the palate meaning it is important in the process of swallowing (Duffy 2013), which is starting…

treat the deficiency of dopamine in the substantia nigra. 70% of the dopamine containing neurons will be lost causing dopamine deficiency and turns the tissue black. Major regions of brain are affected, lower region of the brain stem known as medulla oblongata, which moves up through the basal ganglia into cortical areas (56). Dopamine metabolites increase the reactive oxygen level that…

back to normal. Rebreathing from a closed bag, such as the Ziploc bag we placed over our noses and mouths, results in a raise of PCO2. The increase in the depth of breathing is due to a higher concentration of carbon dioxide, hence causing the medulla oblongata and pons, or the breathing center of the body, to be stimulated to a higher degree than “normal”. Furthermore, breathing rate increases when blood is acidic, when there is too much carbon dioxide in the blood. This most likely happened…

The upper gastrointestinal tract is composed of five major organs and structures: the oral cavity and salivary glands, pharynx, the esophagus, the stomach, and duodenum. Each of these structures assists in the digestive functions of the body. The oral cavity is where mechanical digestion begins. Salivary glands secrete saliva to create a bolus. The bolus is then swallowed, moving through the pharynx to the stomach. In the stomach the bolus is mixed with digestive enzymes, acid, and mucin…

The hypothesis was that the average heart rate would decrease by about 3-8 beats per minute after listening to the Ella Fitzgerald song (with a bpm of 52) for two minutes. The hypothesis also was that after listening to Bach for two minutes (with a bpm of 80,) that the average heart rate of the participants would increase by 5-7 beats per minute, and after listening to Green Day for two minutes (with a bpm of 139,) that the average heart rate of participants would increate by about 7-12 beats…

From the medulla oblongata to the first lumbar nerve is where the spinal cord ends. Just like the brain, that has a protection from the cranium. So, does the spinal cord. Without out the protection of the meninges and the vertebras then it would be effortless to damage…
