Abstract

Upon rapid release from the nerve terminal at a 0.1-1mM concentration, the neurotransmitter acetylcholine (ACh) diffuses through the synaptic cleft separating motoneuron and skeletal muscle, and causes the all-or-none opening of ionic channels from the post-synaptic membrane. Ion flux through these channels selective for sodium, potassium and other small cations (Adams et al. 1980), leads to the depolarization of the post-synaptic cell, and then to muscle contraction.KeywordsAcetylcholine ReceptorNicotinic ReceptorNicotinic Acetylcholine ReceptorElectric OrganHigh Affinity SiteThese keywords were added by machine and not by the authors.
