They are called as vesicles. They are constantly created. They contents the neurotransmitter. Neurotransmitter is required for transmission of the nerve impulse.
an axon terminal
The tip of a neuron's axon culminates in several endings call terminal buttons. When an action potential is conducted down the axon, this is where it goes.
The part of the neuron where neurotransmitters are released from is the axon terminal, and they are released into a small space between neurons called the Synapse.
Axosomatic
The neurotransmitter is released from the axon terminal.
Small bulb like structures at the end of an Axon are called Terminals or Terminal Buttons.

When an action potential reaches the axon terminal, it triggers the opening of voltage-gated calcium channels. Calcium ions enter the axon terminal, leading to the fusion of neurotransmitter-containing vesicles with the synaptic membrane. The neurotransmitter is then released into the synaptic cleft where it can bind to receptors on the postsynaptic neuron.
Axosomatic
The gap between the axon terminal and muscle cell is called the synaptic cleft. It is defined as the small gap, measured in nanometers, between an axon terminal and any of the cell membranes in the immediate vicinity.
