T/F - Protein synthesis occurs inthe presynaptic area.
|
False. In humans, proteins are made in the cell body.
|
|
|
What are the 5 steps of neurotransmission?
|
1. Uptake/Synthesis
2. Storage 3. Release 4. Reception 5. Inactivation |
|
|
What is the primary mechanism for NT release?
|
Exocytosis
|
|
|
What are the three ways in which inactivation of neurotransmission can occur?
|
1. Catabolism
2. Re-uptake 3. Uptake |
|
|
Reuptake (uptake1) is dependent on what?
|
Na+ dependent
|
|
|
Uptake 2 is dependent on what?
|
Na+ dependent
|
|
|
Uptake 1 is specific for what?
|
Neurons using THAT neurotransmitter
|
|
|
What does it mean that the NT do "kiss and run."
|
Vesicles doesn't release all the NT's.
|
|
|
T/F - Chemical neurotransmitters are all or non mechanisms.
|
False - they are graded
|
|
|
Describe the affinity of peptidergic neurotransmission
|
Greater than chemical NT
|
|
|
Describe the inactivation of peptidergic NT's.
|
Degradation.
NO uptake |
|
|
What is Dale's principle.
|
All terminals of the same neuron release the same neurotransmitter(s).
|
|
|
T/F - The distribution pattern of neuropeptides are random.
|
False - Neither general nor random.
|
|
|
T/F - Certain neuropeptides co-exist with other specific chemical NT's.
|
False - no obvious rules determining which neuropeptides coexist with which other transmitters.
|
|
|
T/F - Peptidergic NT's have very specific behavioral and physiological effects.
|
True
|
