It starts the transmission of a neural signal from one neuron to another.
An axon ends in an axon terminal, which ends in a small rounded tip called the axon bulb. Each terminal lies very close to either a dendrite or a cell body of another neuron, and the combination of the end of the first neuron, the beginning of the next, and the space between them is known as a synapse; when a neural impulse reaches the axon bulb, it is stimulated to release chemical messengers called neurotransmitters into the synaptic cleft (gap), which diffuse over to the second neuron, conveying the signal to the second neuron.
axon hillock = where cell body meets the axon axon bulb = end of the axon...lies very close to the dendrites of another neuron so impulses can pass over the synapse. AP Biology student *
The neurotransmitter released at the axon bulb is acetylcholine.
Small bulb like structures at the end of an Axon are called Terminals or Terminal Buttons.
Small bulb like structures at the end of an Axon are called Terminals or Terminal Buttons.
The synaptic bulb is found at the end of axon terminals in neurons. It is the structure responsible for releasing neurotransmitters to communicate with other neurons or target cells at a synapse.
The axon is a single process extending from the axon hillock, sometimes covered by a fatty layer called a myelin sheath that conducts nerve impulses away from the cell body of the neuron.Distal tips of axons are telodendria, each of which terminates in a synaptic knob.
The axon is a long, slender projection that carries electrical impulses away from the cell body. The axonal terminal, or synaptic knob, is the end of the axon that forms a synapse with another neuron or target cell. The synaptic knob contains neurotransmitter vesicles that are released into the synapse to communicate with the next cell.

what is the axon made of
An axon hillock is a special cell body that connects an axon to a neuron. It is the last place where propagated membrane potentials are transmitted to the axon.
Bouton does not belong as it refers to a swollen region along an axon where synapses are found, while axon terminal, synaptic knob, and axon collateral are all parts of the structure of a neuron.
