1
Q
Synapse
A
able to change and adapt in response of neuron firing
2
Q
Electrical synapses
A
Fast response
3
Q
Chemical synapses
A
- slower, but controlled response
- much more abudant
- more selective
- use neurotransmitters (chemical signals)
4
Q
Gap junctions
A
- super fast
- bidirectional
- synchronizattion among neurons
- coorfination intracellular signaling (everything can pass)
5
Q
Co-transmitters
A
molecules when more than one transmitter is present within a nerve terminal
6
Q
Nevn de 3 typene nevrotransmitter
A
- Small Molecule Neurotransmitter
- slow axoplasmic transport- Monoamines
- Amino acid
- Neuropeptides
- Fast axoplasmic transport - Gaseous neurotransmitter
7
Q
4 ways of signal termination
A
- Reuptake by presynaptic neuron
- Enzymatic degradation
- Diffusion away from synapse
- Removal of neurotransmitter from glial cells
8
Q
Drug effect
A
Changes in psysiological processes and behavior of an individual
9
Q
Site of action
A
point at which drugs interact with molecules located on or in cells
10
Q
Pharmacokinetics
A
- what the body does to a drug
- how the drug enters your body
- how it gets distrubuted in your body
- how it gets active in your body
11
Q
the 4 fases of Pharmacokinetics
A
- Absorption
- the process by which a drug gets acsess to the bloodstream from the side of drug administration
- the speed of this process is called durate of drug expostion - Metabolism
- the process by which drugs is chemically changes by lepsolitime form sutibable for absorption and disstribution to a more water sutibible form that is excretion - Excretion
- the process of which drugs endamitabolice are removed from the body
12
Q
Agonist
A
substance that promotes activity of neurotransmitters
13
Q
Antagonist
A
substance that reduces the activity of neurotransmitters
14
Q
Placebo
A
inactive substance
