When an action potential reaches an axon terminal, what happens to the neurotransmitters?
When an action potential reaches an axon terminal, it triggers the release of neurotransmitters into the synaptic cleft.
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.
Are action potential and local potential reversible?
Under normal circumstances action potential will proceed unilaterally. An action potential cannot proceed down an axon and depolarize in the reverse direction on the same axon. It must carry information on one axon in one direction and then on another axon in a separate direction. In a lab you can depolarize neurons in the middle of an axon and it will depolarize bilaterally.
What happens when the impulses reaches the axon terminal?
Neurotransmitters are released and go into the synaptic cleft.
What does not belong axon terminal synaptic knob bouton axon collateral?
Bouton does not belong as it refers to a swollen region along an axon where synapses are found, while axon terminal, synaptic knob, and axon collateral are all parts of the structure of a neuron.
When an action potential reaches an axon terminal, what happens to the neurotransmitters?
When an action potential reaches an axon terminal, it triggers the release of neurotransmitters into the synaptic cleft.
If the neurons threshold is reached what happens?
When a neuron's threshold is reached, it triggers an action potential, which is an electrical impulse that travels along the axon. This occurs due to the rapid influx of sodium ions into the neuron, leading to depolarization. Once the action potential propagates down the axon, it can stimulate the release of neurotransmitters at the synapse, allowing communication with other neurons. This process is essential for transmitting signals throughout the nervous system.
What part of a neuron relays signals from one neuron to another neuron or to an effector?
The axon terminals of a neuron are responsible for relaying signals from one neuron to another neuron or to an effector, such as a muscle or gland. When an action potential travels down the axon, it triggers the release of neurotransmitters at the axon terminals, which then stimulate 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 THE FUNCTION OF THE MIDDLE EAR?
The tympanic membrane in the middle ear transforming sound waves into mechanical vibrations. These vibrations stimulate the inner ear.
What happens when the impulses reaches the axon terminal?
Neurotransmitters are released and go into the synaptic cleft.
Is and axon bulb and an axon hillock the same thing?
axon hillock = where cell body meets the axon axon bulb = end of the axon...lies very close to the dendrites of another neuron so impulses can pass over the synapse. AP Biology student *
What is the result of sodium ions moving across the axons membrane during an action potential?
a neural impulse(electrical impulse) is released and it travels down the axon of a neuron to the axon terminals. At the axon terminal there are sacs called synaptic vesicles which contain chemicals called neurotransmitters. When the neural impulse reaches the terminal it causes the sacs to move closer to the membrane of the axon terminal and release the neurotransmitters inside. Then neurotransmitters travel across the synaptic gap and stimulate the dendrites of another neuron and the whole process starts again.
The axon is connected to the soma by the?
axon hillock
The axon is made up of?

What is a axon hillock?
An axon hillock is a special cell body that connects an axon to a neuron. It is the last place where propagated membrane potentials are transmitted to the axon.
