What are synaptic vesicles, and where are they located?
|
Synaptic Vesicles are located in the terminal boutons of the presynaptic neuron and contain neurotransmitters...
|
|
What are receptor sites?
|
Pockets on the surface of the postsynaptic neuron which receive Neurotransmitter molecules.
|
|
The activation of the receptor site has one of two oppsoite effects on the ion channel and on the dentritic potential of the post synaptic cell... what are they?
|
EPSP
IPSP |
|
What is EPSP?
|
Excitatory Post-Synaptic Potential.. more likely to generate its own Action Potential
|
|
What is IPSP?
|
Inhibitory Post-Synaptic Potential...less likely to generate its own action potential
|
|
How can you create action potential in the postsynaptic neuron?
|
Through Spatial and Temporal Summation of EPSPs
|
|
Definie Spatial Summation.
|
Combining the effects of many EPSPs occuring SIMULTANEOUSLY from synapses all over receptive zone of postsynaptic neuron.
|
|
Define Temporal Summation
|
Combining the effects of a number of EPSPs that occur within a short time at the same synapse.
|
|
Tricyclic antidepressants
|
Blocks reuptake of norepinephrine and serotonin inro PREsynaptic neuron, keeps them in the synapses longer
|
|
Prozac
|
selective serotonin reuptake inhibitor (SSRI)... presynaptic cell
|
|
Monoamine Oxidase (MAO)
|
MAO breaks down monoamine neurotransmitters for reuse. MAO inhibitors used to treat depression, allows monoamine neurotransmitters to remain in cleft.
