Essay On Calcium Channels

Calcium regulation has significant effects on the human body's capacity to maintain homeostasis. Around 99% of the body's calcium is found within the skeleton in the form of calcium salts. The remaining 1% is found in blood and controlled within a very narrow range by an elaborate system of controls to provide for fundamental processes (Marieb & Hoehn 2010). Calcium is the most abundant cation found in human bodies, vital to normal function of a host of processes including: nerve excitability,

disease. Claudin-16 is encoded by CLDN-16 and CLDN19 encode the claudin-19. (1) Michelis et al. was the first person to find this disease, he reported that the feathers are excessive magnesium and calcium losses with urinary, bilateral nephrocalcinosis and progressive chronic renal failure. (11) In this essay, I will discuss the role of tight junction proteins in familial hypomagnesaemia with hypercalciuria and nephrocalcinosis (FHHNC). Magnesium is the fourth most cation in the body, its

proposed that epilepsy is "an occasional, an excessive and a disorderly discharge of nervous tissue". About 65 million people(1% of the human population) in the world have epilepsy and the cases account for 80% in developing countries. [3][4] In this essay, the normal physiology of nerve transmission in cerebral cortex and pathophysiology of epilepsy will be discussed. The mechanism of action of valproate is also studied and how it leads to the treatment of epilepsy. Normal Physiology of Nerve Tranmission

The purpose of this essay is to explain the mechanisms of neural communication, and the influence that different drugs have on this communication. The nervous system is made up of several cells that are called neurons, which are situated inside the Central Nervous System (Martin, Carlson & Buskit, 2013). Neurons comprise of three mechanisms, a cell body which is referred to as the soma, dendrites and an axon (Pinel, 2011). The cell body comprises of the nucleus and other organelles (Ward, 2010)

This essay examines the physical, mental and social aspects of Kevin who is diagnosed with Atrial Fibrillation (AF) and a known case of transient ischaemic attack(TIA). Atrial flutter or AF is an arrhythmia which lead to severe cardiac complications. TIA is a nervous system deficit which occurs as a result of impaired blood flow and usually settle down within 24 hours hence it is a short term episode. Kevin who is a farmer, lives on his own, needs a thorough understanding of his present situation

It is important for graduate nurses to be familiar with chest pain management and therapeutic interventions as chest pain can evolve rapidly and require quick responses from nurses and collaborative teams. This essay will critically analyse the nursing care of a patient presenting to the emergency department with the primary compliant of chest pain. In this particular case, the patient’s chest pain is being caused an acute coronary syndrome (ACS) possibly an acute myocardial infarction (AMI) (Kervinen

organization media center think that heart attack and strokes is the leading cause of bleeding from a blood vessel in the brain or from blood clots. However, there are many risk factor and causes with cardiovascular disease can be prevented and in this essay discuss the medical treatment and surgical. There are many causes of cardiovascular disease. First of all, Ford-Martin (2005), Atherosclerosis is the main cause of cardiovascular disease when in body accumulation of fatty

Discuss the role of proteins in cell membrane transport essay plan Cell membranes are surrounded by a phospholipid bilayer that provides a semipermeable barrier for cells, separating the cytosol from the extracellular environment. Phospholipids are ampithatic, meaning that they have a hydrophilic head and hydrophobic tail, which causes the heads to face outwards towards the water and the tails inwards, creating the bilayer [figure 1]. Small hydrophobic molecules such as O2 and CO2 and small uncharged

Topic: Discuss the technologies available for treating cardiovascular disease via gene therapy and the future direction of this as a therapeutic option. Introduction The definition of cardiovascular disease as stated by the British Heart Foundation is as follows, “cardiovascular disease includes all diseases of the heart and circulation, including coronary heart disease (i.e. angina, heart attack), heart failure, congenital heart disease, and stroke. It is also known as heart and circulatory disease

The concept of critical care nursing has transformed intensely since its origin in the 1960’s. The discipline of nursing and the specialty of critical care nursing are expected to advance and transform, just the way health care delivery system has reformed over the last few decades (Morton & Fontaine, 2013). Never before have there been significant advancements in technology, surgeries, therapies, imaging alternatives, diverse procedures, pharmacology and innovative research modalities being delivered
