Abstract :
Acetylcholinergic receptors(AChRs)have two distinct types:muscarinic receptors(mACHRs)and nicotinic receptors(nAChRs).The mAChRs belong to large class of integral membrane glycoproteins that mediate cholinergic processes like learning,memory and attention while the nAChRs are groups of ligand-gated . . .
