After neurotransmitters are released in to the synaptic cleft - from the presynaptic neuron, they bind with there specific receptor cites found on the postsynaptic neurons cell membrane. Some neurotransmitters then become inactive by enzymes whiles other simply drift away from the synaptic cleft. Reuptake can also occur where the presynaptic neuron sponges up (or takes back) the remaining neurotransmitters left behind.

What releases neurotransmitters into the synapse?

Neurotransmitters are released into the synapse by the presynaptic neuron.


What happens when neurotransmitters communicate an excitatory message to the postsynaptic neuron?

When neurotransmitters communicate an inhibitory message to the postsynaptic neuron:


Where are neurotransmitters released?

Neurotransmitters are released from the axon terminal of a neuron into the synaptic cleft, which is the small gap between the axon terminal and the dendrite of a neighboring neuron. neurotransmitters then bind to receptors on the receiving neuron, transmitting the signal.


What is it called when neurotransmitters are recycled?

The process of recycling neurotransmitters is known as reuptake. This is when neurotransmitters are taken back up into the presynaptic neuron after they have been released into the synaptic cleft.


What are neurotransmitters that affect a neuron's response to other neurotransmitters called?

These are typically known as neuromodulators; they can either change the rate at which a neurotransmitter is released, or alter the response to a certain neurotransmitters.


Where are neurotransmitters released by neurons?

The axon terminal, into a synapse.


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.


Action potentials trigger the release of chemicals in the terminal buttons called?

neurotransmitters. These neurotransmitters are released into the synaptic cleft to relay signals to the next neuron in the communication pathway.


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.


What happens when the impulses reaches the axon terminal?

Neurotransmitters are released and go into the synaptic cleft.


What are retrograde neurotransmitters?

Retrograde neurotransmitters are released from dendrites and alter the activity of neighbouring cells. This process is the opposite of typical neurotransmitters, which are released from the axon terminal (of a post synaptic neuron) and act on dendrites. Two examples are the gaseous neurotransmitters Carbon Monoxide and Nitric Oxide.


What happens if a person have too much or too little amount of neurotransmitters?
