G-Protein Receptors: What Stimulates Sympathetic Autonomy Receptor? (Term Paper Sample)

The process by which stimulation of sympathetic autonomic receptor elicits a response is by co-activation of G-protein receptors using sulfhydryl groups to produce intracellular secondary messengers. Sympathetic receptors are comprised of alpha receptors which are located on the arteries, beta 1 and beta 2. The function of the autonomic receptor is to act as an on and off button to control the various sympathetic effects which occur on the body. Excessive use of drugs can over-stimulate the sympathetic receptor hence causing high blood pressure, dysrhythmias and hyperthermia to the body of an organism and lastly the organism is at high risk of death. Integration in the individual cell can be as a result of G-proteins receptors which act as an important pathway for the demands of an organism which is multicellular. Sympathetic autonomic receptor deals with fight and flight as it binds itself to adrenergic receptor and its stimulated incases of danger. Its stimulation leads to reduction in digestion process which increases the breakdown of fats muscles to provide energy as well as increased blood flow. There are a series of sympathetic ganglia which help in the interaction of sympathetic neurons of spinal cord with peripheral neurons. The autonomic nervous system is made up of a composition of tonically active systems the sympathetic and the parasympathetic. There function is to provide some degree of nervousness in all times to a given tissue. Both the sympathetic system and the parasympathetic have typically opposing effects on a certain tissue. The sympathetic system prepares the body for some physical activities by increasing the flow of oxygenated blood which is rich in nutrients...
