TERMINAL INFLATED PORTION OF THE AXON, CONTAINING THE SPECIALIZED APPARATUS NECESSARY TO RELEASE NEUROTRANSMITTERS. THE AXON TERMINUS IS CONSIDERED TO BE THE WHOLE REGION OF THICKENING AND THE TERMINAL BOUTON IS A SPECIALIZED REGION OF IT.

Axon terminals (also called synaptic boutons, terminal boutons, or end-feet) are distal terminations of the telodendria (branches) of an axon. An axon, also called a nerve fiber, is a long, slender projection of a nerve cell, or neuron, that conducts electrical impulses called action potentials away from the neuron's cell body, or soma, in order to transmit those impulses to other neurons, muscle cells or glands.
