Firing

In the context of neurons, it refers to the transmission of an electrical signal along the neuron.

Resting Potential

The difference in voltage across the neuronal membrane when the neuron is not actively sending a signal, typically around -70mV.

Membrane Potential

The electrical potential difference across a cell's plasma membrane, crucial for the transmission of nerve impulses and muscle contraction.
