When an action potential reaches the nerve terminal, what happens to the neurotransmitter release?
When an action potential reaches the nerve terminal, it triggers the release of neurotransmitters into the synapse.
What happens when an action potential reaches the nerve terminal?
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.
What happens when the action potential reaches the axon terminal"?
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.
What happens when the impulses reaches the axon terminal?
Neurotransmitters are released and go into the synaptic cleft.
What causes a neuron to release neurotransmitters?
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.

What happens when the impulses reaches the axon terminal?
Neurotransmitters are released and go into the synaptic cleft.
When are neurotransmitters released?
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.
When the nerve signal reaches the axon terminal what happens next?
When a nerve signal reaches the axon terminal, it triggers the influx of calcium ions (Ca²+) into the terminal through voltage-gated calcium channels. This influx causes synaptic vesicles containing neurotransmitters to fuse with the presynaptic membrane, releasing the neurotransmitters into the synaptic cleft. The neurotransmitters then bind to receptors on the postsynaptic neuron, leading to the initiation of a new nerve signal in that neuron.
Series of events from the time the action potential reaches the persynaptic terminal to the activation of the postsynaptic receptor?
After the action potential reaches the presynaptic terminal, voltage-gated calcium channels open, leading to an influx of calcium ions. This triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic membrane, leading to depolarization and the generation of a new action potential in the postsynaptic neuron.
How does a signal cross the synaptic gap?
When an action potential reaches the axon terminal of a neuron, it triggers the release of neurotransmitters into the synaptic gap. These neurotransmitters then bind to receptors on the postsynaptic neuron, causing ion channels to open and allow ions to flow in, generating a new action potential in the receiving neuron.
What happens when an impulse reaches the end of an axon?
It reaches the synapse and sends neurotransmitters to start a new impulse to the next neuron
What are released when action potential reach terminal buttons?
When an action potential reaches the terminal buttons of a neuron, it triggers the influx of calcium ions (Ca²+) into the cell. This increase in calcium concentration prompts synaptic vesicles, which contain neurotransmitters, to fuse with the presynaptic membrane and release their contents into the synaptic cleft. The neurotransmitters then bind to receptors on the postsynaptic neuron, facilitating communication between the two neurons.
What causes a neuron to release neurotransmitters?
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.
What are the areas of the neuron that secretes neurotransmitters called?
The areas of the neuron that secrete neurotransmitters are called synaptic terminals or axon terminals. These terminals are located at the end of the axon and contain synaptic vesicles filled with neurotransmitters. When an electrical signal (action potential) reaches the synaptic terminal, it prompts the release of these neurotransmitters into the synaptic cleft, allowing communication with neighboring neurons.
