Neurotransmitters are released and go into the synaptic cleft.
When the impulses reach the axon terminal, calcium ions enter the axon terminal, triggering the release of neurotransmitters stored in vesicles. The neurotransmitters then diffuse across the synaptic cleft and bind to receptors on the postsynaptic neuron, causing a response in the receiving neuron.
It is either inhibitory and nothing happens or excitatory and causes depolorization again. If the axon hillock on the postsynaptic neuron reaches threshold potential then an impulse is transmitted and action potential is reached all over again.
Neurotransmitters are released from vesicles and flood the synapse.

A nerve impulse starts at the dendrite then travels to the?
cell body, continues down the axon, and finally reaches the axon terminal. At the axon terminal, the impulse triggers the release of neurotransmitters to communicate with other neurons or muscles.
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.
What is the structure at the end of an axon that produces neurotransmitters?
The structure at the end of an axon that produces neurotransmitters is called the synaptic terminal or synaptic bulb. It contains vesicles filled with neurotransmitters that are released into the synaptic cleft to communicate with the next neuron or target cell.
What ion enters the axon nerve terminal to cause exocytosis of the neurotransmitter is called?
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.
Is the Axon terminal the same as the terminal buttons?
Yes, Axon terminals and terminal buttons are different terms for the same structure at the end of the neuron that releases neurotransmitters to communicate with other neurons or target cells.
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
A nerve impulse starts at the dendrite then travels to the?
cell body, continues down the axon, and finally reaches the axon terminal. At the axon terminal, the impulse triggers the release of neurotransmitters to communicate with other neurons or muscles.
In which direction does the message travel in the neuron?
it travels through the dendrite to the synaptic terminal to the axon
What is axite?
An axite is any of the terminal branches of an axon. (An axon is a usually long and single nerve-cell process that usually conducts impulses away from the cell body.
What are the function of the nerve fibers?
Arevbranching fibers at the end of the axon that lead the nervous impulse from the axon to the synapse
What major mineral is required for transmission of nerve impulses?
neuro transmitter is essential for the transmission of nerve impulses in nerve fibres.it is a chemical which is present in the axon terminal bulb(ending of a neuron).
What is a word ending in ical that is to do with axons and dendrites?
One word is "neuritical," which refers to structures related to neurons' axons and dendrites.
What is the single long thin extension of the nerve cell that ends with the terminal end bulbs are the?
The single long thin extension of a nerve cell that ends with terminal end bulbs is called an axon. The axon is responsible for transmitting electrical impulses away from the cell body to other neurons, muscles, or glands.
What is the route followed by nerve impulses when one neuron communicates with another?
When one neuron communicates with another, the nerve impulse travels down the axon of the presynaptic neuron, reaches the axon terminal, triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron's dendrites, initiating a new nerve impulse in the postsynaptic neuron.
What is the process of a neurotransmitter being absorbed into the axon terminal?
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.
Where do nerve impulses leave the neuron?
Nerve impulses are transmitted down the axon and leave the neuron via the terminal bouton at the synaptic interface, releasing neurotransmitters into the synaptic cleft to affect the post-synaptic cell..
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 *
