Explanation The six plexus in the thoracic and abdominopelvic cavity are as follows: Cardiac plexus. Pulmonary plexus. Esophageal plexus. Celiac plexus. Inferior mesenteric plexus. Hypogastric plexus. The fibers of the autonomic division of the nervous system meet at the cardiac and pulmonary plexus and carry parasympathetic and sympathetic fibers to the heart and lungs. The esophageal plexus is formed by the branches of vagus nerves and splanchnic nerves and innervates esophagus. The celiac plexus innervates the viscera of the abdominopelvic cavity and the hypogastric plexus innervates the organs of the digestive, reproductive and urinary system of the body. Types of plexuses Effect of sympathetic stimulation Effect of parasympathetic stimulation Cardiac plexus Increase in heart beat and blood pressure...

Glitazones reduce insulin resistance by binding to a transcription factor in adipocytes, thereby reducing thesecretion of fatty acids. Glitazones are taken orally (in pill form). Using pharmacokinetic modeling, deriveequations to describe how the concentration of glitazones varies in the plasma as a function of time. Yourequations should be of the form: dCglitazone /dt = something, or dMglitazone /dt = something. Your model shouldinclude three compartments: the gut, the plasma, and the fatty tissues. Make sure to include a diagram thatillustrates your thinking, state all assumptions, and define your variables. Do not solve the equations.
