Parasympatholytics, also known as anticholinergics or parasympathetic blockers, are a class of drugs that antagonize the effects of acetylcholine (ACh) at muscarinic receptors in the parasympathetic nervous system. These drugs inhibit the parasympathetic nervous system’s actions, leading to various physiological effects. Classification of Parasympatholytics Parasympatholytics can be classified based on their chemical structure or their … Read more

Parasympathomimetics, also known as cholinergic agonists or muscarinic agonists, are drugs that mimic the action of the parasympathetic nervous system by stimulating the cholinergic receptors. These receptors are predominantly found in various organs and tissues throughout the body, including the heart, smooth muscles, exocrine glands, and central nervous system. Classification of Parasympathomimetics Parasympathomimetics can be … Read more

Screenshot 2024 03 30 110635 Organization and function of ANS

The Autonomic Nervous System (ANS) is a critical component of the peripheral nervous system responsible for regulating involuntary bodily functions. It acts largely unconsciously to control various physiological processes, including heart rate, digestion, respiratory rate, glandular secretion, and sexual arousal. The ANS operates through a complex network of neurons, neurotransmitters, and receptors, allowing for precise … Read more
