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‚

Asthma is a condition of the respiratory which is caused by the tightness of the muscles in the airways‚ which therefore causes the individual with this condition to breathe out reduced amount of air which then leads to difficulty in inhaling and exhaling. According to the World Health Organization (2010)‚ this condition is due to inflammation of the air passages in the lungs and affects the sensitivity of the nerve endings in the airways so they become easily irritated. In an attack‚ the lining
