NURS 6630 PSYCHOPHARMACOLOGY STUDY GUIDE/NURS 6630 WALDEN ACTUAL EXAM 2024 LATEST UPDATE 100% GUARANTEED PASS QUESTIONS AND ANSWER ALREADY GRADED A+. Constitutive activity - ANSWER- in the absence of agonist, the receptor's conformation is such that it leads to a low level of activity Antagonists - ANSWER- blocks agonists (both full and partial) from binding to Gprotein-linked receptors, thus preventing agonists from causing maximum signal transduction and instead changing the receptor's conformation back to the same state as exists when no agonist is present Partial agonists - ANSWER- stimulate G-protein-linked receptors to enhance signal transduction but do not lead to maximum signal transduction the way full againsts do classic synaptic neurotransmission - ANSWER- stimulation of a presynaptic neuron (e.g., by neurotransmitters, light, drugs, hormones, nerve impulses) causes electrical impulses to be sent to its axon terminal. These electrical impulses are then converted into chemical messengers and released to stimulate the receptors of a postsynaptic neuron.
