Adrenergic Agonists (Sympathomimetics)

Adrenergic agonists are autonomic nervous system drugs that stimulate the adrenergic receptors of the sympathetic nervous system (SNS), either directly (by reacting with receptor sites) or indirectly (by increasing norepinephrine levels). An adrenergic agonist is also called a sympathomimetic because it stimulates the effects of SNS.

Nervous System Anatomy and Physiology

The nervous system is involved in some way in nearly every body function. All the sensations, actions, and emotions are made possible by the nervous system, which consists of the brain, spinal cord, nerves, and sensory receptors.
