Neurotransmitters released by 1 nerve cell are received by?
Neurotransmitters released by 1 nerve cell are received by another neuron. The receptor of a postsynaptic neuron receives the neurotransmitters.
Where are the receptors for neurotransmitters located?
Receptors for the various neurotransmitters are located on both the presynaptic and postsynaptic nerve terminals of the neuron.
Do neurotransmitters always cause hyperpolarization of the postsynaptic membrane?
No, many neurotransmitters cause the postsynaptic membrane to be depolarized.
Certain mental problems are thought to be caused by not having enough neurotransmitters. Why would a lack of neurotransmitters cause problems?
Neurotransmitters send signals from neuron to neuron
Which cell must have action potentials to produce one or more action potentials in the postsynaptic cell?
A neuron (nerve cell) receives dendritic input in order to generate action potentials to transmit signals of the same. After the action potential triggers release of neurotransmitters in the axonal terminal of that neuron, those neurotransmitters propagate the signal forward to the next neuron, and so forth.
What happens when neurotransmitters communicate an excitatory message to the postsynaptic neuron?
When neurotransmitters communicate an inhibitory message to the postsynaptic neuron:
Neurotransmitters communicate an inhibitory message to the postsynaptic neuron?
reuptake is inhibited
Neurotransmitters released by 1 nerve cell are received by?
Neurotransmitters released by 1 nerve cell are received by another neuron. The receptor of a postsynaptic neuron receives the neurotransmitters.
What are characteristics of neurotransmitters?
Neurotransmitters are released in response to stimulation. They alter the physiology of the postsynaptic cell. They are synthesized by a presynaptic neuron. They bind to specific receptors on the postsynaptic cell.
These lipid molecules may function as retrograde neurotransmitters and allow the postsynaptic neuron to decrease release of neurotransmitter from the presynaptic neuron?
endocannabinoids
Where are the receptors for neurotransmitters located?
Receptors for the various neurotransmitters are located on both the presynaptic and postsynaptic nerve terminals of the neuron.
How does neurotransmitters initiate depolarization?
Let's picture a presynaptic neuron, a synaptic cleft, and a postsynaptic neuron. An action potential reaches the terminal of a presynaptic neurone and triggers an opening of Ca ions enters into the depolarized terminal. This influx of Ca ions causes the presynaptic vesicles to fuse with the presynaptic membrane. This releases the neurotransmitters into the synaptic cleft. The neurotransmitters diffuse through the synaptic cleft and bind to specific postsynaptic membrane receptors. This binding changes the receptors into a ion channel that allows cations like Na to enter into the postsynaptic neuron. As Na enters the postsynaptic membrane, it begins to depolarize and an action potential is generated.
Do neurotransmitters always cause hyperpolarization of the postsynaptic membrane?
No, many neurotransmitters cause the postsynaptic membrane to be depolarized.
What determines the effect that a neurotransmitter has on the postsynaptic neuron?
the receptors on the postsynaptic membrane
Explain what happens to neurotransmitters after they are released?
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.
