Document Summary

Sites of drug action: antagonist: o a drug that opposes or inhibits the effects of a particular neurotransmitter on the postsynaptic cell, agonist: o a drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell. The neurotransmitters: catecholamines are synthesized by single aa called tyrosine, acetylcholine. Idol-amines are synthesized by aa called tryptophan o. Primary neurotransmitter secreted by efferent axons of the pns. All muscular movement is accomplished by the release of ach o o the acetylcholinergic neurons located. In the dorsolateral pons play a role in rem sleep (dream) In the basal forebrain play a role in learning (perceptual learning) In the medial septum control the electrical rhythms of the hippocampus and modulate its functions (memories) o composed of two components. Choline -> a substance derived from the breakdown of lipids. Acetate -> the anion found in vinegar o two drugs affect the release of ach.
