Nervous system
| Question | Answer |
|---|---|
| Movement of the membrane potential away from zero | Hyperpolarization |
| Movement of the membrane potential toward zero | Depolarization |
| Ion channel that open in response voltage fluctuation | voltage gated channels |
| A few milliseconds after the absolute refractory period where the membrane repolarized | relative refractory period |
| the space between a synaptic knob and the plasma membrane of a postsynaptic neuron | synaptic cleft |
| If the sum of the local potentials reaches the threshold potential, voltage-gated channels in the axon membrane open, producing an action potential | spatial summation |
| when synaptic knobs stimulate a postsynaptic neuron in rapid succession, their effects can add up over a brief period to pro-duce an action potential | temporal summation |
| neurotransmitters are synthesized from amino acid molecules | amine |
| serotonin and histamine. Monoamines have a single amine | monoamine |
| the most common inhibitory neurotransmitter in the brain. | GABA Gamma-aminobutyric acid |
