Study Notes
Drugs Affecting Autonomic Activity
- Autonomic nervous system (ANS) junctions are ideal targets for pharmacological manipulation due to their chemical transmission.
- Drugs can influence the ANS by affecting neurotransmitter synthesis, storage, release, breakdown, reuptake, or receptor binding.
Parasympathetic Nervous System
- The parasympathetic nervous system is one branch of the ANS.
Sympathetic Nervous System
- The sympathetic nervous system is the other branch of the ANS.
ANS Transmission
- ANS transmission is chemically mediated.
- Autonomic fibers can be either cholinergic or adrenergic.
- Each fiber type has unique distributions, neurotransmitters, receptors, and mechanisms of action.
