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.
Neurotransmitters are released into the synapse by the presynaptic neuron.
When neurotransmitters communicate an inhibitory message to the postsynaptic neuron:
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.
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.
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.
The axon terminal, into a synapse.
When an action potential reaches an axon terminal, it triggers the release of neurotransmitters into the synaptic cleft.
neurotransmitters. These neurotransmitters are released into the synaptic cleft to relay signals to the next neuron in the communication pathway.
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.
Neurotransmitters are released and go into the synaptic cleft.
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.
