This produces an endplate potential (EPP) that spreads across the surface of the muscle fiber into the transverse tubules, eliciting the release of calcium from the sarcoplasmic reticulum, thus initiating muscle contraction (15).
Neuromuscular transmission which was suppressed by tubocurarine in the in vitro preparation could be briefly restored by application to the nerve of two or more very closely spaced stimuli; this occurred because of summation of endplate potentials.
Excitatory miniature endplate potentials (MEPPs) and evoked potentials (EPPs) were recorded with standard microelectrode techniques.
