End plate potentials (EPPs) are the voltages which cause depolarization of skeletal muscle fibers caused by neurotransmitters binding to the postsynaptic membrane in the neuromuscular junction. They are called "end plates" because the postsynaptic terminals of muscle fibers have a large, saucer-like appearance.

In contrast, the shapes of end-plate potentials (EPPs) at neuromuscular junctions and of excitatory post-synaptic potentials (EPSPs) in nerve cells may look much more like the response of a passive membrane despite the presence of active channels in the membrane.

An end-plate potential (EPP) is generated when the ACh released from the nerve terminal interacts with the nAChR located postjunctionally in the end-plate region of the muscle, causing the receptor ion channel to change conformation, open, and thus conduct inward ionic currents that depolarize the region surrounding the end plate. This results ...

Because ACh activates cation-permeable receptors at the NMJ, this transmitter generates an end plate potential (EPP), which is one specific type of excitatory postsynaptic potential (EPSP), and which is explained in the following way.

The first is known as the endplate potential or EPP and represents synchronous release of multiple vesicles in response to nerve stimulation. The EPP is directly coupled to Ca 2+ entry induced by the action potential. It gives rise to the graded depolarization of the end plate.

A typical recording trace is shown in Figure 10, where the stimulation artifact (proportional to the amplitude of the stimulation), the EPP, proportional to nerve terminal activity and the mEPPs can be distinguished.

PSPs are called excitatory (or EPSPs) if they increase the likelihood of a postsynaptic action potential occurring, and inhibitory (or IPSPs) if they decrease this likelihood.
