Irreversible blockade of AChE are used as insecticides and lethal weapons, atropine and scopolamine interfere with learning of different tasks, metabotropic; 5 subtypes (M1-M5), in midbrain, dopaminergic cell activity: excitatory effect on DA neurons, mediate the rewarding effects of morphine, in muscarinic receptors; phosphoinositide, inhibition of cAMP, and opening of K+ channels, Inotropic, sodium and calcium, powerful activation of CNS, weak activation in neuromuscular junctions, found in muscles, ANS, and brain, both ACh sites must be occupied to open the channel for Na+ and Ca ++, sympathetic and parasympathetic system, Brain: increase NT release when in presynaptic location and rate of firing when located on postsynaptic membrane, Continuos activation by agonist alters the state of the receptor, neocortex, stratum, hippocampus, basal forebrain, Laterdorsal and pedunculopontine segmental nuclei (project to VTA). Acetylcholine (ACh) is one of the most abundant neurotransmitters in the human body. Oh no! Match. In the peripheral nervous system, ACh activates muscles that help the body move.
