The Synaptic Cleft or Synapse
... A neuron’s axon ends in many small swellings called axon terminals. At the axon terminal the neuron may meet dendrites of another axon or an effector, like a muscle or gland. The space where neurons meet other neurons or effectors is called the synapse. There are presynaptic neurons and postsynaptic ...
