Graded Potential: Graded potential refers to a membrane potential, which can vary in amplitude.
Graded potential | definition of graded potential by Medical dictionary Depending on the cell and type and the nature of stimulus, graded potentials that lead to action potentials are called synaptic potentials (i.e., post-synaptic potential changes in neurons), generator potentials or receptor potentials (graded potentials in sensory cells causes by adequate stimuli), or end-plate potentials (i.e., synaptic
