To give general information about autonomic nervous system, and to prepare the basis for understanding the drugs related to autonomic nervous system

The innervation and activation of these systems by the parasympathetic (cholinergic), sympathetic (adrenergic) and non-adrenergic non-cholinergic (NANK) systems that make up the OSS are different. Drugs that affect OSS may affect the synthesis, storage, release, metabolism of the mediators involved in this system, as well as on receptors stimulated by these mediators or post-receptor events. In this course, the mechanism of action of OSS drugs will be explained by giving examples of drugs acting on these mechanisms.
