graded (local) potentials

Yes, Graded potentials (otherwise known as postsynaptic potentials) can form on receptor endings.
Postsynaptic potentials are changes in the membrane potential of the postsynaptic terminal of a chemical synapse. Graded potentials are changes in membrane potential that vary in size, as opposed to being all-or-none, and are not postsynaptic potentials.
Action potentials also known as spikes, differ from graded potentials in that they do not diminish in strength as they travel through the neuron.
Graded Potentials
On the dendrites and subsequently the soma (body) of neurons.
conduction and summation of graded potentials.
they depend on the number of receptors activatedthey sum up and have no refractory period thus exhibit spatial and temporal summationthey have no threshold -depends on the concentration of ligand(stimulus)they cant be propagated
graded potentials
chemically regulated gates, voltage regulated gates
No, they actually decrease in amplitude as they move away from the stimulus point.
