belladonna
|
natural source of alkaloids with anticholinergic activity acquired from the deadly nightshade plant, Atropa belladonna, which grows throughout the world
|
|
cholinergic crisis
|
caused by an overdosage with acetylcholinesterase (AchE) inhibitors or poisoning with organophosphate insecticides or toxic nerve gases; characterized by intense signs of parasympathetic stimulation such as miosis, nausea, vomiting, urinary incontinence, increased exocrine secretions, and abdominal cramping
|
|
curare
|
the first neuromuscular blocker, which was initially extracted from several different plant species native to the rainforests of South America
|
|
ganglionic blockers
|
drug that inhibits transmission at the ganglia in the sympathetic and parasympathetic nervous systems
|
|
malignant hyperthermia
|
rare condition that is an adverse effect of some general anesthetics characterized by a sudden onset of tachycardia, ventricular dysrhythmia, and hypotension
|
|
motor end plate
|
cholinergic synapse on skeletal muscle that allows for communication between the nervous system and skeletal muscle
|
|
muscarinic antagonists
|
drugs that block receptors at cholinergic synapses in the parasympathetic nervous system and at a few target organs in the sympathetic nervous system
|
|
neuromuscular blockers
|
drug used to cause total muscle relaxation
|
|
nicotinic antagonists
|
drugs that block receptors at cholinergic synapses in the ganglia or in the somatic nervous system at the neuromuscular junction
|
|
nondepolorizing neuromuscular blocker
|
class of nicotinic antagonists that bind to Ach receptors at motor end plates in skeletal muscle and prevent Ach from reaching its receptors
|
|
pseudocholinesterase
|
enzyme that rapidly destroys certain drugs in the plasma
