The Physiology and Pathophysiology of the Skin Abstract The 5-HT3 receptor is a ligand-gated cation channel located in the central and peripheral nervous system; it has also been detected on a variety of other cells. In the periphery‚ it is found on autonomic neurons and on neurons of the sensory and enteric nervous system. In the CNS‚ the 5-HT3 receptor has been localized in the area postrema‚ nucleus tractus solitarii‚ nucleus vaudatus‚ nucleus accumbens‚ amygdala‚ hippocampus‚ entorhinal‚

MODULE 3 Innate Immunity 1. Describe the composition‚ function‚ and the purpose of physical‚ mechanical‚ and biochemical barriers‚ The first line of defense against damage and infection is composed of tightly associated epithelial cells including those of the skin and the mucous membranes of the GI‚ GU‚ and respiratory tracts. The highly interconnected mucosal epithelial cell junctions prohibit the passage of microorganisms. Many infectious microorganisms are mechanically cleansed

In any case‚ there are a few theories that attempts to clarify the pathophysiology of schizophrenia. Variations from the arrangement of the nervous system and abnormal changes in the cerebrum are in fact‚ the reasons for the disorder. The nervous system abnormalities lie in the wrong arrangement of contacts between nerve cells

Introduction: Having a sound understanding of pathophysiology is imperative for all allied health practitioners within the Australian healthcare system. Pathophysiology is defined to be the functional changes associated with particular diseases (Webster‚ 2016). Knowledge of pathophysiology and its related mechanisms is essential as it helps with the thorough understanding of certain diseases‚ its aetiology and its impact on the patient’s day-to-day life (ANZPAC‚ 2012). The aim of all healthcare practitioners

Most theories on the pathophysiology of depression are based on measurement of indirect markers‚ neuro-imaging techniques‚ and post-mortem studies. Studies show that depression starts with abnormalities in the areas of the brain that are responsible for reward response‚ mood regulation‚ and executive functions. The neuro-imaging and post-mortem studies have indicated morphological changes shown by reductions in grey-matter volume and glial density in the prefrontal cortex and the hippocampus‚ which

Chronic pancreatitis pathophysiology is unclear. However‚ Long tern alcohol use causes hypersecretion of protein in pancreatic productions‚ this then causes protein plugs and calculi to form inside the pancreatic channels. Therefore‚ alcohol abuse has a direct poisonous impact on the cells of the pancreas. Subsequently‚ patients with eating regimens such as low protein and high or low in fat are more at risk. Smoking is another aspect on the improvement of chronic pancreatitis (J V. Tsirambidis‚
