* electrical receptor
* excitatory synaptic

An action potential is a(n) ______________ transient change in neuronal membrane potential. Another important form of intraneuronal communication is a(n) _____________ (or local) potential, referring to ____________ changes in membrane potential. One type is a(n) _____________ potential, which is produced in response to neurotransmitter release by presynaptic partners. The other type is a(n) _____________ potential, which can be induced at peripheral nerve endings by sensory stimuli. Regardless of the source, inputs can be either excitatory or inhibitory. _____________ inputs facilitate action potential production by the postsynaptic neuron, while _____________ inputs make it less likely. _____________ neurons do not fire
