What goes on when an action potential is transferred from one neuron to the next through a synapse?
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.

When the action potential gets to the end of the axon?
When the action potential reaches the end of an axon, it causes special chemical messages called neurotransmitters to be released across the space between the neurons (the synapse).
What is the difference between action potentials and synaptic potentials?
A synaptic potential exists at the INPUT of a neuron (dendrite), and an action potential occurs at the OUTPUT of a neuron (axon). (from OldGuy)(from Ilantoren:) A synaptic potential is the result of many excitatory post synaptic potentials (epsp) each one caused by the synaptic vesicles released by the pre-synaptic terminus. If there are enough of these epsp then the responses will summate and depolarize the post-synaptic membrane at the axon hillock enough to fire an action potential.
How are neurotransmitters important in action potential propagation?
Neurotransmitters are chemicals released by neurons that carry signals across the synapse to stimulate the next neuron in the chain. They play a crucial role in influencing action potential propagation by either triggering or inhibiting the generation of new action potentials in the postsynaptic neuron. This process helps in the transmission of nerve signals through the nervous system.
When the neuron is sussiciently stimulated this process and triggers the action potential?
When a neuron is sufficiently stimulated, it depolarizes, allowing sodium ions to rush into the cell, triggering an action potential. The action potential travels down the length of the neuron, causing the release of neurotransmitters at the synapse and facilitating communication with other neurons.
When an action potential reaches the end of a neuron it triggers the release of?
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.
What is the relationship between the action potential and the synapse?
A synapse and an action potential have a flip-flopping cause and effect relationship, in that an action potential in a presynaptic neuron initiates a release of neurotransmitters across a synapse, which can then subsequently potentially trigger an action potential in the axon of the postsynaptic neuron, which would then cause release of neurotransmitters across a following synapse.
How does information travel through synapse?
When an action potential reaches the end of a neuron, it triggers the release of neurotransmitters into the synapse. These neurotransmitters then bind to receptors on the receiving neuron, causing ion channels to open and allowing ions to flow in, which generates a new action potential in the receiving neuron, thus continuing the signal.
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.
The action potential causes neurotransmitters to be released into the?
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.

What is synaptic potential?
A synaptic potential is a change in the electrical potential of a neuron in response to the release of neurotransmitters at a synapse. It can be either excitatory, causing depolarization and promoting action potential firing, or inhibitory, causing hyperpolarization and reducing the likelihood of action potential firing. These changes in potential are essential for communication between neurons in the brain.

What is the method of communication between neurons?
Neurons communicate with each other through electrical and chemical signals. When an action potential is generated in one neuron, it travels down the axon and releases neurotransmitters at the synapse, which then bind to receptors on the neighboring neuron, causing either excitation or inhibition of the receiving neuron.
