Overview of the autonomic nervous system

It was stated at the beginning that the peripheral autonomic system has a prominent place as a site of drug action. We will now look at the organization of this system, and at the distribution of transmitter receptors within it. This will enable us to understand the effects of drugs acting upon this system and rationales behind their usage. 

The target tissues that are controlled by the secondary neurons (the ones originating in the ganglia) include  

A take-home message from table 7.1 is that, by and large, muscarinic receptors mediate the parasympathetic effects, whereas the sympathetic ones are mediated by adrenergic receptors. 

From the effects of the autonomic nervous system on the various target organs (table 7.1), we can easily imderstand several applications of dmgs that cause S5maptic stimulation or inhibition  

Other options are concerned with the suppression of the allergic / inflammatory process that trigger the bronchial constriction in the flrst place.
