When an action potential reaches the nerve terminal, it triggers the release of neurotransmitters into the synapse.
When an action potential reaches an axon terminal, it triggers the release of neurotransmitters into the synaptic cleft.
When an action potential reaches the nerve terminal, it triggers the release of neurotransmitters into the synapse, which then transmit signals to the next neuron or target cell.
When the action potential reaches the axon terminal, it triggers the release of neurotransmitters into the synapse, which then bind to receptors on the neighboring neuron, continuing the signal transmission.
The ion that enters the axon nerve terminal to trigger neurotransmitter release is calcium (Ca2+). When an action potential reaches the nerve terminal, voltage-gated calcium channels open, allowing calcium ions to flow into the cell and initiate the process of exocytosis of neurotransmitter-containing vesicles.
Calcium ions trigger the release of neurotransmitter at the presynaptic membrane. When an action potential reaches the presynaptic terminal, it causes voltage-gated calcium channels to open, allowing calcium ions to enter the cell. The influx of calcium ions triggers the fusion of synaptic vesicles with the presynaptic membrane, leading to the release of neurotransmitter into the synaptic cleft.

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.

It reaches the synapse and sends neurotransmitters to start a new impulse to the next neuron
Communication across a synapse is initiated by the release of a neurotransmitter from the axon terminal of the presynaptic neuron. When an action potential reaches the axon terminal, it triggers the influx of calcium ions, leading to the fusion of neurotransmitter-containing vesicles with the presynaptic membrane. This process causes the neurotransmitters to be released into the synaptic cleft, where they bind to receptors on the postsynaptic neuron and facilitate communication.
Calcium ions (Ca²⁺) must flow into the presynaptic cell for neurotransmitter release. When an action potential reaches the presynaptic terminal, voltage-gated calcium channels open, allowing Ca²⁺ to enter the cell. This influx of calcium triggers the fusion of neurotransmitter-containing vesicles with the presynaptic membrane, leading to the release of neurotransmitters into the synaptic cleft.
When an action potential reaches the axon terminal of the presynaptic neuron, it triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron, leading to changes in its membrane potential. This process either excites or inhibits the postsynaptic neuron, depending on the neurotransmitter and receptor type involved.
Calcium ions cause the neurotransmitter vesicles to fuse with the axon terminal. When an action potential reaches the axon terminal, voltage-gated calcium ion pores are opened, allowing calcium ions into the axon terminal. These ions initiate the release of neurotransmitter vesicles stored on elements of the cytoskeleton located near the presynaptic membrane; they then travel to the presynaptic membrane, where they first dock, and then fuse with the presynaptic membrane, forming an opening or pore through which the neurotransmitters are released into the synaptic cleft.

The influx of calcium ions triggers the fusion of synaptic vesicles with the presynaptic membrane, leading to the release of neurotransmitter into the synaptic cleft.
In general, action potentials that reach the synaptic knobs cause a neurotransmitter to be released into the synaptic cleft. The arrival of the action potential opens voltage-sensitive calcium channels in the presynaptic membrane.
