Neurotransmitter Flashcards
Who many neurotransmitters have been identified?
More than 70
Binary neurotransmitters
Certain neurotransmitters
Can be: inhibitory , excitatory
Based on: sites
Acetylcholine
A se tol ko lin
Both, usually excitatory
Where Acetylcholine are?
Prevalent: forebrain>hippocampus
Every synapse: neuron terminates at a skeletal muscle fiber
Why Acetylcholine is in brain?
formation of new memories
Acetylcholine is important in which disease?
Alzheimer’s disease
Why Acetylcholine is important in Alzheimer’s disease?
Less Acetylcholine
More serious memory loss
Why Acetylcholine in important in muscles work?
Muscles contractation
How Acetylcholine makes muscle’s contract possible?
1.every synapse - neuron terminates at a skeletal muscle fiber
2.To: end plates(coverd with receptors) on musclee
3.Molocular linkage
4.Contract
Drugs for Acetylcholine, muscle pralization, death
botulinum toxin
Block releasing
How botulinum toxin is produced
bacteria in improperly canned food
What neurotransmitter is influenced by nerve gase?
How?
acetylcholine
- destroying the enzyme that degrades acetylcholine once the neuron has fired
- normal synaptic transmission×
Where Norepinephrine is purdused?
Brainstem
Drugs connected to Norepinephrine
Cocaine. Amphetamines
lithium
Effect of cocaine and amphetamines
Norepinephrine for too long
- Slow reuptake
- Prolong prosses
- Receiving neurons active for longer
- Psychological effects
