Sodium ions enter … WebJul 5, 2012 · 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 ... WebThe 'average' neuron has 1000 neurons that synapse on it and tell it what to do by creating graded potentials. Some are excitatory ( depolarizing) and some are inhibitory (hyperpolarizing). If the sum of the graded potentials cause the membrane at the axon hillock to reach threshold, then this 'average' neuron will have an active potential. grade 12 life orientation source based task

WebGraded potentials can be summed (added) on top of one another to increase the change. Stated another way, if a stimulus is repeated over and over, it can result in an even larger deviation toward zero, from rest or away from rest to more negative values. This is the reason why the changes are called graded. The amplitude (change in the membrane ... WebThere is a deep connection between force and potential energy.
