The terms "аgоnist" аnd "аntagоnist" are central tо the study and classification of neurotransmitter receptors. A receptor agonist is a drug that binds to a receptor and causes a response similar to that caused by the receptor's normal neurotransmitter. Acholinergic receptor agonist is a drug that binds to and activates one or more receptor types that normally are activated by acetylcholine. Acholinergic receptor antagonist is a chemical that has the opposite effect.A cholinergic agonist (note that the word "receptor is omitted) is any drug that stimulates acetylcholine-employing synapses, regardless of whether the drug acts: 1) presynaptically, by stimulating acetylcholine neurotransmitter release, 2) in the synaptic cleft, such as by preventing acetylcholine elimination, or 3) postsynaptically, by activating one or more acetylcholine receptor types, or making it easier for acetylcholine to bind to its receptor.Question: For the following three sentences, determine if the condition would best be treated with a drug that is a cholinergic agonist or an antagonist.1. In Alzheimer's disease, there is a loss of cholinergic signal transmission in the brain, and patients are given a cholinergic_________.2. In myasthenia gravis, antibodies may reduce the ability of acetylcholine to bind its receptors in skeletal muscle. These patients may benefit from therapy with drugs that are cholinergic_________.3. A farm worker severely poisoned by an insecticide that prevents acetylcholine function will benefit from receiving a cholinergic_________. The correct answers should be, in order:
