extension of a neuron that receives input from axons of other cells and conducts signal towards cell body presynaptic terminal axon terminal excretes signaling molecules, or neurotransmitters postsynaptic specialization found on dendrites, receptive sites for neurotransmitters synaptic cleft gap that separates presynaptic and postsynaptic neurons axon long extension from neuron cell body that carries electrochemical signal away to presynaptic terminals interneurons neurons within the brain and spinal cord that communicate internally and intervene between the sensory inputs and motor outputs action potential electrical signal that is carried down the axon axon hillock region where axon initiates, also where signal initiates chemical synapse synapses where information is transmitted via the secretion of signaling molecules (neurotransmitters) synaptic vessicles
