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.
Calcium (Ca2+) channels open on the synaptic end bulb in response to depolarization (from the action potential), inducing exocytosis of synaptosomes containing neurotransmitter, resulting in neurotransmitter being released into the synaptic cleft...further propagating the signal to the next neuron or set of neurons.
The substance found in synaptic vesicles is usually neurotransmitters such as dopamine, serotonin, or glutamate. These substances are released into the synapse when an action potential reaches the axon terminal, helping transmit signals from one neuron to another across the synaptic cleft.
Neurotransmitters are the substances found in synaptic vesicles of axon terminals. These neurotransmitters are released into the synapse, where they transmit signals from one neuron to another. Some common neurotransmitters include dopamine, serotonin, and acetylcholine.
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.

Synaptic vesicles are found in the axon terminals of nerve cells.
Calcium (Ca2+) channels open on the synaptic end bulb in response to depolarization (from the action potential), inducing exocytosis of synaptosomes containing neurotransmitter, resulting in neurotransmitter being released into the synaptic cleft...further propagating the signal to the next neuron or set of neurons.
The nerve signal arrives at a synaptic knob and causes calcium channels to open. This allows the calcium ions to enter the synaptic knob. Calcium ions entry into the synaptic knob triggers exocytosis of synaptic vesicles, which release acetylcholine into the synaptic cleft.
The sack-like structures inside the synaptic knob containing chemicals are called synaptic vesicles. These vesicles store and release neurotransmitters, which are chemical messengers that transmit signals between neurons. When an action potential reaches the synaptic knob, it triggers the release of neurotransmitters from the synaptic vesicles into the synaptic cleft.
The tiny sacs in the synaptic knob are known as synaptic vessels. The synaptic vessels release chemicals into the bloodstream with each synapse.

The small space separating pre and post-synaptic neurons is called the synaptic cleft. This cleft allows for the transmission of chemical signals, known as neurotransmitters, from the pre-synaptic neuron to the post-synaptic neuron to occur. The neurotransmitters are released by the pre-synaptic neuron and bind to receptors on the post-synaptic neuron to transmit the signal.

The type of light bulb base commonly found in a regular light bulb is called an Edison screw base.
