WebAcetylcholine is known to have excitatory actions at neuromuscular junctions, at certain glandular tissues, at autonomic ganglion, and in the central nervous system (often abbreviated to the central nervous system). It is known to have inhibitory actions in the cardiac muscle and at certain smooth muscles. WebIn neuroscience, an excitatory postsynaptic potential ( EPSP) is a postsynaptic potential that makes the postsynaptic neuron more likely to fire an action potential. This temporary depolarization of postsynaptic membrane potential, caused by the flow of positively charged ions into the postsynaptic cell, is a result of opening ligand-gated ion ...

WebAcetylcholine (ACh), one of the brain’s most potent neuromodulators, can affect intrinsic neuron properties through blockade of an M-type potassium current. The effect of ACh on excitatory and inhibitory cells with this potassium channel modulates their membrane excitability, which in turn affects their tendency to synchronize in networks. WebAcetylcholine is known to have excitatory actions at neuromuscular junctions, at certain glandular tissues, at autonomic ganglion, and in the central nervous system (often …

WebIt is generally believed that ACh is an inhibitory neurotransmitter in molluscan heart. However, ACh can cause not only inhibition but also excitation or both inhibition and excitation, depending on the species and, in some cases, on the concentration of ACh (Greenberg, 1965; Pilgrim, 1954 ).
