Q
Receptor communication
Pharmocology + ?
A
pharmacology
neuronal signalling
3
Q
what happens at presynaptic axon terminal
NT synth- repuptake- Metabolism
A
- Neurotransmitter synthesis - Synaptic vesicle transporters - Reuptake transporters
Enzymes to metabolise neurotransmitters
4
Q
- What happens after the receptor is activated??
Channels- Receptors - proteins
A
- Postsynaptic dendrite:
- Transmitter-gated ion channels (ionotropic receptors) G-protein-coupled receptors (metabotropic receptors) G-proteins
G-protein-gated ion channels
Second messenger cascades
5
Q
how do Neurotransmitters communicate with the post synaptic cell
A
via RECEPTORS
6
Q
Receptors are connected to ?
I - G
A
- ion channels (ionotropic receptors) or to
- G-proteins (G-protein coupled receptors and second messenger cascades) or to
- G-protein coupled ion channels

Q
what is function of NT binding to receptors?
Excit. or Inhib.
A
produces biological effect which is either excitatory or inhibitory to the cell or cell system
