Cholinergic physiology
WebCholinergic drugs work by stimulating the body's nicotinic and muscarinic receptors. Nicotinic receptors are involved in muscle tone, memory, analgesia, cognitive function, motor control, arousal ... WebIn the immune system, nAChRs regulate inflammatory processes and signal through distinct intracellular pathways. [1] In insects, the cholinergic system is limited to the central nervous system. [2] The nicotinic receptors are considered cholinergic receptors, since they respond to acetylcholine.
