When an action potential reaches the end of a neuron's axon, it triggers the release of neurotransmitters from vesicles in the presynaptic terminal into the synaptic cleft. This process is mediated by the influx of calcium ions that enter the neuron during an action potential, causing the vesicles to fuse with the cell membrane and release their contents.
synaptic cleft. This release allows the neurotransmitters to bind to receptors on the postsynaptic neuron, leading to changes in its membrane potential and potentially initiating a new action potential in the receiving neuron.
Neurotransmitters are stored in small sacs called vesicles within the axon terminals of a neuron.
When an action potential reaches the end of a neuron, it triggers the release of neurotransmitters into the synaptic gap. These neurotransmitters then bind to receptors on the neighboring neuron, causing ion channels to open and allowing the impulse to continue along the second neuron. The neurotransmitters are then either broken down or taken back up by the original neuron to end the signal.
Neurotransmitters are stored in small sacs called vesicles located at the end of the axon terminal in a neuron.
Neurotransmitters are used to send messages from cell to cell, usually neuron to neuron. Neurotransmitters are released from the pre-synapse, which is at the axon terminus. These neurotransmitters are picked up by the post-synapse on the receiving cell. These post-synapses are located on structures called dendrites or on the cell body.

neurotransmitters send signals from neuron to neuron
Neurotransmitters are released when an action potential reaches an axon terminal (aka: end foot, synaptic knob, bouton), causing voltage-gated calcium ion gates to open, allowing calcium ions into the axon terminal, which causes vesicles containing the neurotransmitters to fuse to the cell membrane, which creates an opening to release the neurotransmitters into the synapse.
The neurotransmitters from one neuron have direct effect on the next neuron. They are channels that are used to transmit messages in the nerves.
neurotransmitters from the synaptic vesicles into the synapse. These neurotransmitters then bind to receptor proteins on the adjacent neuron, initiating a new action potential in the postsynaptic neuron.
They don't, the neurotransmitters stay on either side of the synapse. Neurotransmitters are released when the synaptic vesicles fuse with the presynaptic neuron's membrane, so as to release them into the synaptic cleft.
Neurons communicate with each other by sending electrical signals across a synapse. In a three neuron loop the series of events that happen in synaptic transmission are as follows: Neuron 1 sends an electrical signal (action potential) down its axon towards the synapse. The action potential causes the release of neurotransmitters (chemicals) from the terminal button of Neuron 1 into the synaptic cleft. The neurotransmitters bind to the receptors of Neuron 2. This binding triggers a new action potential in Neuron 2 which travels down its axon. The action potential causes the release of neurotransmitters (chemicals) from the terminal button of Neuron 2 into the synaptic cleft. The neurotransmitters bind to the receptors of Neuron 3. This binding triggers a new action potential in Neuron 3 which travels down its axon. The action potential causes the release of neurotransmitters (chemicals) from the terminal button of Neuron 3 into the synaptic cleft. The neurotransmitters bind to the receptors of Neuron 1 closing the loop.This series of events is repeated continuously allowing for the communication between neurons in a three neuron loop.
endocannabinoids
When the action potential reaches the button(axon terminal) of the presynaptic neuron the depolarization causes voltage gated calcium channels to open increasing intracellular calcium content. This causes synaptic vesicles to fuse to the membrane and release neurotransmitters that bind to the post synaptic neuron and create a chemical action potential.
When neurotransmitters communicate an inhibitory message to the postsynaptic neuron:
