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‚

Exam Case Scenario Pathophysiology of Asthma Asthma is a chronic lung disease characterized by episodes in which the bronchioles constrict due to oversensitivity. In asthma‚ the airways (bronchioles) constrict making it difficult to get air in or out of the lungs. Breathlessness is the main symptom. The bronchi and bronchioles become inflamed and constricted. Asthmatics usually react to triggers. Triggers are substances and situations that would not normally trouble an asthma free person. Asthma

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

he pathophysiology of ADHD is unclear and there are a number of competing theories.[87] Research on children with ADHD has shown a general reduction of brain volume‚ but with a proportionally greater reduction in the volume of the left-sided prefrontal cortex. These findings suggest that the core ADHD features of inattention‚ hyperactivity‚ and impulsivity may reflect frontal lobe dysfunction‚ but other brain regions particularly the cerebellum have also been implicated.[88] Neuroimaging studies

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

Practice reflects human rights ... Having been aware of the fact that VB was not happy with the terminology‚ enabled me to address her properly and practice what Roger’s called “positive regard” (Payne‚ 2005). I did this by valuing VB for who she felt she was and being compassionate as she related her story to me. Ultimately‚ best practice in the service delivery is to ensure that we respect the Human Rights Convention ( ) since the UK has been signed up to it for 50 years. The tendency is that

There is no cure for asthma‚ but the majority of patients that receive proper treatment can continue with a normal life (Wexler‚ B. 2013).

Asthma is the attack of the Paroxysmal dyspnea where airway inflammation and wheezing occur due to contraction
