Q

Resting Potential

A

Na+ cannot enter, or is actively pumped out of, the

neuron; the cell is negatively charged

Depolarisation

A

Na+ enters dendrites and cell body, making the cell less

negatively charged

Q

action potential

A

If the change in axon voltage surpasses a threshold, the

axon suddenly lets in a surge of Na+

Q

neurotransmitter release

A

The action potential causes terminal buttons to release

neurotransmitters into the synaptic cleft

Q

chemical message released

A

Depending on the facilitating or inhibitory nature of the
neurotransmitter released, the voltage of the cell membrane
receiving the message becomes depolarised or
hyperpolarised, and the process repeats
