Excitatory junction potential | definition of excitatory junction potential by Medical dictionary
excitatory junction potential
ex·cit·a·to·ry junc·tion po·ten·tial (EJP),
discrete partial depolarization of smooth muscle produced by stimulation of excitatory nerves; similar to small end-plate potentials; summate with repeated stimuli.

Bursts of action potentials in these motor neurons drive summating excitatory junction potentials
(EJPs) in specific sets of muscle fibers.
Finally, patterned firing by the motor neurons themselves produce facilitating or depressing excitatory junction potentials
in the buccal muscles (Cohen et al.
Stimulation at A did not produce unitary excitatory junction potentials
(EJPs), but did produce frequency-dependent summing depolarizations.
