Synaptic boutons, also known as axon terminals, are small swellings found at the ends of axons.
They are usually the locations of synapses with other neurons, and neurotransmitters are retained there to converse with other neurons through these synapses.
Axon terminal inflated portion containing the highly specialised apparatus required for neurotransmitter release. The axon terminus is thought to be the entire region of thickening, and the terminal bouton is a subset of it.
Axon terminals are button-like structures at the end of axons that are responsible for supplying synapses between neurons. The axon terminal contains neurotransmitters, which are initially found inside synaptic vesicles.
Neurotransmitters are chemicals that are stored in synaptic vesicles.
The synapse is made up of three parts:
1) the presynaptic membrane, which is formed by an axon's terminal button,
2) the postsynaptic membrane, which is made up of a dendrite or cell body segment, and
3) the space between these two structures, known as the synaptic cleft.
