Contraction of smooth muscle by acetylcholine is mediated by activation of muscarinic receptors of which M2 and M3 subtypes are present in longitudinal muscle of guinea pig intestine.he rise in internal calcium suppresses the voltage-dependent inward calcium current. A third important effect is the opening of channels which cause depolarization of the membrane and so increase action potential discharge and contraction in the whole muscle.
Inhibition of Acetylcholinesterase at the Neuromuscular Junction I. Background Acetylcholine is the neurotransmitter used at the neuromuscular junction to generate muscle contractions. Acetylcholine (ACh) is released when an action potential reaches the axon terminus of a motor neuron.his Ca 2+ triggers the movement of ACh filled vesicles to the pre-synaptic nerve cell membrane and the exocytotic release of ACh. ACh then diffuses across the neuromuscular junction and binds to its receptor on the post-synaptic cell membrane (in this case, the plasma membrane of the muscle cell).
