Cholinergic Receptors 🧠 Flashcards
Tertiary Amine
A type of amine compound where the nitrogen atom is only bonded to alkyl groups, often possessing pharmacological properties.
Acetylcholine Effects
Include vasodilation, decrease in cardiac rate, decrease in conduction rate, and decrease in force of contraction.
COPD
A chronic obstructive pulmonary disease characterized by a gradual loss of lung function over time, including emphysema and chronic bronchitis.
Cholinergic Drugs
Include Cholinergic Agonists and Cholinergic Antagonists that interact with the cholinergic receptors in various organ systems.
Direct -acting Agonists
Cholinergic agonists that bind to and activate muscarinic or nicotinic receptors.
Indirect -acting Agonists
Cholinergic agonists that inhibit acetylcholinesterase, leading to increased acetylcholine levels.
Atropine
A muscarinic antagonist that blocks muscarinic receptors, causing effects like mydriasis, cycloplegia, and decreased salivary secretions.
Asthma
A respiratory condition marked by spasms in the bronchi of the lungs, causing difficulty in breathing due to inflammation and constriction of the airways.
Muscarinic Antagonists
Substances that block the action of acetylcholine at muscarinic receptors, leading to various effects including relaxation of smooth muscles.
Ganglion Blockers
Drugs that interfere with the transmission of signals between nerves by blocking ganglionic synapses, affecting autonomic nervous system functions.
Nicotinic Receptor Antagonists
Compounds that inhibit the action of acetylcholine on nicotinic receptors, which are involved in neuromuscular transmission.
Neuromuscular Blockers
Drugs that prevent communication between nerves and muscles, leading to muscle relaxation and paralysis during surgeries or other medical procedures.
