Neurotransmitters Flashcards
1
Q
Ach-excitatory
A
Nicotinic –> ionotropic, sodium channel
M1, M3, M5 –> increases in calcium (metabotropic)
2
Q
Ach-inhibit
A
M2, M4 –> decreases in calcium or cAMP or opens a G-protein-gated K+ channel (metatropic)
3
Q
GABA- inhibit
A
GABAa –> ionotropic, chloride channel
4
Q
Glutamate - excitatory
A
NMDA, AMPA–> ionotropic sodium + calcium channels
5
Q
Norepinephrine - excitatory
A
Alpha-1 –> increased IP3 and calcium (metabotropic)
Beta-1 –> increased cAMP (metabotropic)
