Final answer:
Graded potentials can result from sensory stimuli and are associated with dendrites. If received by a sensory neuron dendrite, it is a generator potential, while if received by a specialized sensory receptor cell, it is a receptor potential. Graded potentials produced by interactions between neurons at synapses are called postsynaptic potentials.
Step-by-step explanation:
Graded potentials can result from sensory stimuli. If the stimulus is received by the dendrites of a unipolar sensory neuron, it is called a generator potential and can directly generate the action potential in the initial segment of the axon. If the stimulus is received by a specialized sensory receptor cell, it is called a receptor potential. Graded potentials produced by interactions between neurons at synapses are called postsynaptic potentials (PSPs). A depolarizing graded potential at a synapse is called an excitatory PSP, and a hyperpolarizing graded potential is called an inhibitory PSP.
